Title: “Angles Don’t Matter”
Post by: Ben Sims on February 08, 2023, 08:22:26 PM
“Angles Don’t Matter”

“Fairways Don’t Have Proper Sides”

These are both quotes from the data manager of Arccos Golf, Lou Stagner. I decided I was tired of being a golf nut that sucks at golf and I’m working hard to get better. This led me to data analysis and Arccos Golf. Turns out, all the stuff I thought I knew about getting better at golf is sort of old hat.


That said, this modern take on shot tracking and by default, scoring, also has an affect on golf architecture. What’s your viewpoint when you read quotes such as these? Keep in mind that Lou Stagner has over 600 MILLION golf shots from which to draw conclusions.

Angles matter less and less the better you become. If you can hit high long shots from the fairway as well as the rough, it’s likely you can fly over trouble. Even if short sided.

Depends on which golfers and conditions you are taking about. Even TOC made angles matter at last year's Open.

When corses are soft angles don’t matter. Once they get firm they can matter a lot.

Being in the fairway is great if you want to beat an opponent who is not. This is especially true at a course like Prairie Dunes where angles are everything.

Angles matter when the ball is rolling. This discussion isn't new; there are several other topics with this line of discussion.

Golf course architects are a deluded bunch. We still hang our hat off designing strategic golf because it is one of the main cornerstones of the job. But deep down, we know!


Now with that said, I too would like to see numbers on a course we consider highly strategic Vs an average one. I think that on courses with very, very firm greens and wind, you have to have a high swing speed and good spin and descent for them not to matter at all. I play off 4 and I know courses where they matter more for me than other courses. But I reckon there’s a sweet spot of playing ability. Counterintuitively, I bet they don’t really matter for the weaker player either. Because they are not in control of their ball enough for a trend to be spotted.


But I’m guessing… dish some more data, Ben.

I’d like to see a comparison of four groups of courses:


- PGA Tour courses
- US Top 100 courses built before WWII
- Every course built by TD or C&C
- GB&I Top 100 links courses


I have my opinions of the order these would fall out in “angles matter”. I’d be fascinated to see if I was right.

The various stats LS highlights have some merit but not for every player, every course, every day etc. They are a generalisation.
They can be however thought provoking and if considered in relation to your own game and where you are playing on any given day and the likes of the weather and course conditions on the day in question may be of some assistance.

I'd also like to see a comparison by ability.  Intuitively, angles matter more for those whose shots spend more time rolling, rather than landing and stopping.  Teen handicappers stop the ball much less quickly than pros, so I'd expect angles to matter more for me than the best.

I guess I need some clarification on the OP.  Is the claim really that angles don’t matter for any player in any situation on any course?  Or just that it doesn’t happen often enough to be statistically relevant?


I have looked over the ShotLink data for two older courses - Waialae and Cherry Hills - and I couldn’t find any pattern of players aiming for one side of the fairway over another, or of guys making more birdies from drives on one side.


Unfortunately, the European Tour doesn’t track and color-code the result of each drive, so I haven’t seen good data for The Renaissance Club, and only for the first year of the event in Houston, not for the last two.


But are we just talking about Tour players (who rarely have an approach shot over 150 yards), or everyone?

If the conditions or level of player is such that pin positions matter, then so do angles. 


I agree that for soft courses angles mean little, especially in comparison to elevation changes, bowls, or false fronts.

If you enjoy flighting the ball down and bouncing into greens a la links golf in Scotland and Ireland, angles and fairway position can be everything. I mean ... if there is a bunker covering the front right half of the green, you better be on the left side of the fairway to play your second if you want to run one in. Obviously, a scratch golfer on a calm day who likes to fly it to the yardage and stop the ball on a dime won't be affected by position, and probably will end up scoring better. Bt will that person have more fun? I don't know. I wouldn't.

What about launch angle?  Does that angle matter?  Why is he trying to sell me a product that optimizes my launch angle, but then tells me angles don’t matter? Seems like a conflict of interest. If angles used to matter and now they don’t, the only explanation is a better launch angle. Clever marketing and golf has always gone hand in hand.

Isn't it --angles don't matter as much as distance?


The way I understand the Stagner/Fawcett/Barzeski/Strokes Gained approach (I'm sure there are nuances between them). You can't reliably get the best angle unless you sacrifice distance (and dispersion) and being closer outweighs almost any angle. Hit your drive as far as you can where you take hazards out of play by aiming between any hazards at your carry distance and live with the dispersion and possible bad angle. If you bring a hazard into play (within your drive dispersion) by chasing the angle the math doesn't work over the long term.

If there is some severe contour in the fairway I bet angles matter a lot. This is why my favorite thing is contour, big rollers, small chop, you name it.

Post by: Tim Gavrich on February 09, 2023, 10:20:22 AM
Knowing what trends emerge after 600 million golf shots is useful, but it's not everything. There are all sorts of variables in a single round that can - and should - cause a player to play a more conservative or aggressive shot than the Stagners and Fawcetts of the world might suggest in a vacuum.

As I understand them, their models would have counseled against Max Homa taking dead aim at the pin, hitting a fade that started over the front-left bunker, on the 16th at Torrey Pines a couple of weeks ago. But Homa took it on, and it arguably won him the golf tournament. They probably would have advised Bubba Watson to just pitch out of the trees at the 2012 Masters, too.

A great thing about golf is that every round is unique, and typical or average individual situations are not the only ones you or I encounter in a given set of 18 holes. I don't see a lot of acknowledgment of that fact in their almighty models. Any attempt to force objectivity on something as variable as a round of golf is going to have limitations. Their research provides a good base from which to selectively diverge (the more opportunities a golf course provides to diverge, the better it is, I find), but it's not God, even if they act like zealots sometimes.

Angles don't matter (much at all) when the ball isn't rolling.

From the PGA Tour right up to 20 handicappers, players on the "optimal" side of the hole actually score slightly worse than players on the "wrong" side of the fairway. Ditto for being in the rough on the "wrong" side versus the "correct" side. We're talking tenths or hundredths of a shot.

Why? Often… b ecause when you're on the "wrong" side you play more conservatively, and when you're on the "correct" side you play more aggressively. Ideally, players would play to almost the same places regardless of their "angle" if they were interested in scoring the best.

I have looked over the ShotLink data for two older courses - Waialae and Cherry Hills - and I couldn’t find any pattern of players aiming for one side of the fairway over another, or of guys making more birdies from drives on one side.
Right. I've shared the graphic from before for PGA Tour player data, and… it's basically the same. They score about the same from the fairway, on either side. For the same reasons as above. The data is fairly consistent across a large range of players.

But are we just talking about Tour players (who rarely have an approach shot over 150 yards), or everyone?
Unless you define "rarely" in a weird way… that's not correct. I may dig up the stat, but Tour players are approaching from farther out than y'all seem to think.

Heck, look at the number of approaches from 125-150 (https://www.pgatour.com/stats/detail/329) and 150-175 (https://www.pgatour.com/stats/detail/328). From 2021-22:
No, this quick look doesn't show 100-125, but it also doesn't show 175-200, which happens more than y'all might think. But I think it clearly shows that saying "rarely" is incorrect.

If the conditions or level of player is such that pin positions matter, then so do angles.
Sure. Mostly, as I keep noting, when the ball is rolling… either because they don't hit it far/high enough to get it in the air and stop a little, or the ground is firm (i.e. Melbourne during the Presidents Cup).

Am I the only one who remembers that we've had this discussion about ten times already in the last four or five years?

Isn't it --angles don't matter as much as distance?
Yes, but more because angles don't really matter much (except when rolling), so almost everything else matters more. Distance, fairway vs. rough vs. hazards… etc.

The way I understand the Stagner/Fawcett/Barzeski/Strokes Gained approach (I'm sure there are nuances between them). You can't reliably get the best angle unless you sacrifice distance (and dispersion) and being closer outweighs almost any angle.
Not quite. You can hit driver and "try" to be on the left side of the fairway, or "try" to be on the right side of the fairway. But it's generally dumb to do so.

Imagine a fairway that's symmetrical. Maybe it's just rough on both sides, or an equal fairway bunker on each side, whatever. In this case, you're generally best to aim at the middle of the fairway, so the highest percentage of your shots are in the fairway, regardless of the angle. Fairway > rough and angles don't matter.

Now imagine a fairway where there's a penalty of some kind on one side (a creek, a deep bunker, etc.). It's the better "angle" but it's the dumber play by far - your pattern should be centered around the other side of the fairway, sometimes even into the rough slightly depending on the severity of the hazard (like OB/lost ball). In this way the "angle" matters… but it's the angle you take off the tee, not the angle into the green.  In this case, fairway > rough > penalty/obstruction/hazard.

Hit your drive as far as you can where you take hazards out of play by aiming between any hazards at your carry distance and live with the dispersion and possible bad angle. If you bring a hazard into play (within your drive dispersion) by chasing the angle the math doesn't work over the long term.
Yes. Pretty much that.

There are all sorts of variables in a single round that can - and should - cause a player to play a more conservative or aggressive shot than the Stagners and Fawcetts of the world might suggest in a vacuum.
There are always going to be outliers.

As I understand them, their models would have counseled against Max Homa taking dead aim at the pin, hitting a fade that started over the front-left bunker, on the 16th at Torrey Pines a couple of weeks ago. But Homa took it on, and it arguably won him the golf tournament. They probably would have advised Bubba Watson to just pitch out of the trees at the 2012 Masters, too.
They would have, but Max also won by more than one shot, and it could have cost him the tournament, too. You're looking at one event and one outcome and comparing it to the way to shoot the lowest average score. As we wrote in LSW, for example… the way to play the hole for the lowest average score may be different than the way to have the best chance of making birdie when you don't care about also increasing the chances of making double or higher.

I don't see a lot of acknowledgment of that fact in their almighty models.
You do realize that when talking to the general "golfer" base, whether it's me with LSW, or Lou, or Scott… we kinda have to talk about general things. But in working with the players with whom I've worked… for example… there are some holes that just suit a player's eye, and even though the "math" says "do X" they're better off doing Y, or Z. Or there are times when they're just feeling it, and they're counseled to diverge.

The models we all have are baselines. You can't apply them in a total paint-by-numbers way, nor do we tell people - individual people - to do that. When talking to the masses, though, you have to give the generalized info.

63% are longer than 150. I have a hard time getting behind a definition of "rarely" that's synonymous with "the majority."  :)

P.S. Remove par threes and it's still well over 50%.

It's curious that you reference getting better more than shooting lower scores. I think analytics is probably a good way to shoot lower scores regardless of whether you get any better. I think analytics is a better and more well thought-out version of what we used to call "playing within yourself". I think actually getting better is more of a mastery over what happens when you hit a ball. Whether you choose the smart play on the course is another matter entirely.

But I am also doubting your math at the end.  If 53% of approaches are over 150 yards, and you remove the par-3's, how is it still well over 50% ?  What % of the par-3's on Tour are under 150 yards?


I'm also surprised that the % under 100 yards is so small.  But, I don't watch the average Tour event, ever.  They must have pretty much eliminated short par-4's on most of those courses.  They sure didn't want many of them in Houston, for pace of play reasons.

Post by: Jason Topp on February 09, 2023, 02:45:57 PM
I have started a few threads on this topic.  My recollection is that the preferred angle does not improve average score at all.   If in the fairway, a player scores just as well from the “bad” side as the good side.  From what I have seen the data is pretty compelling.  Basically - one looking to optimize score should hit it in play and as far as possible.  The player should choose a target that takes into account the scatter plot of her tee shots. 


If accurate, this data undermines the fundamental concept underlying strategic design - tempt a hazard to gain an advantage.  I think there may be a mental component that still makes strategic design the best approach but good players are unlikely to be consciously approaching a round in those terms.

Jason:


I spent a fair bit of time wrestling with this question before we started our work at Memorial Park.  Of course, I wasn't thinking solely about Tour players, but also the people that play the other 60,000 rounds there each year.


It helped a lot to talk to Brooks Koepka about it.  He felt very strongly that tactics matter on a well designed course, and that the reason he performed better at the majors was because tactics mattered more there, and many of today's players just blow them off as unimportant.


For Brooks, strategy was less about what side you missed on off the tee, and much more about what side you missed on for the approach shot to each particular hole location . . . though, on the best holes, playing in from one angle will make it easier to miss in the right spots.  As a result, we tried very hard at Memorial to come up with greens complexes where the Tour pro safety valve of missing to the center of the green did not pay off so predictably.  We tried to put a contour or a fallaway or something in the middle, to make you either pick a side, or live with the uncertainty of where a shot in the middle might finish up.  I think that worked pretty well.


Brooks is also famous for having said "rough doesn't matter", but the #1 thing I was pleased to hear from other players was that being in the rough at Memorial DOES matter . . . the potential of flyer lies means that the players have to be much more conservative on their approach if they've missed the fairway.  And that was basically Brooks's idea, to combine the Bermuda rough with tight grass and slopes around the greens where a wild approach shot could get away from you.  Of course, that doesn't mean the players are hitting irons off the tee for position . . . because they aren't much more likely to be in the fairway with an iron, and it isn't worth giving up the distance for that added accuracy.


I wish he was more famous for saying "bunkers don't matter," because we agreed early on there was no way to make bunkers there that would seriously impact a Tour pro's strategy, so we should probably have as few of them as possible.

I have been reading a book on cognitive bias and this could be a prime example of that but the Houston tournament has seemed to provide a different and more interesting test than other tour venues.  The equation is definitely different.

That may be true, but I don't think it necessarily is true. Someone has already brought up the idea that being on the wrong side may result in more conservative play, which is often the correct play anyway. Additionally there is the possibility that most courses (even those played by the pros) are only really loosely strategic at best. And finally, there is the conditioning. All added up, they blunt the effects as far as I'm concerned, and don't take away the efficacy of truly strategic design.


It might mean that we need to alter the types of hazards and features we use in order to influence play. Rough and sand don't really force the player to hit lower-trajectory shots, maybe more use of severe contours or trees would help force lower shots, especially on better players.

IMO
Firm conditions making distance control a premium are the test
When players are hitting it as high as they do, angles matter with (as Erik mentioned) firm conditions.


But perfect and consistent greens, even compared to my generation, will not make these players as worried about 30+ foot putts.


Give them room in the fairways and it’s hard to hide anything!

Sorry - it's 63%. The numbers in the chart represent the start of the range. So 150 means approaches from 150 to 159.

That's not your fault. I initially posted 63%, then edited it to say 53%, and thought I changed it back when I got clarification that I was right (150 = 150 to 159) the first time, but apparently I didn't. Or I didn't save it or something.

If accurate, this data undermines the fundamental concept underlying strategic design - tempt a hazard to gain an advantage.  I think there may be a mental component that still makes strategic design the best approach but good players are unlikely to be consciously approaching a round in those terms.
Yes. Except when the ball is rolling. Or if you're just looking at what makes golf interesting to you. It's important to understand that this is generalized data and the data speaks to scoring, not engagement, or fun, or interest, etc.

Brooks is also famous for having said "rough doesn't matter"
He's either really dumb OR he meant it a bit differently than it may seem. I think the latter.Dumb is if he really doesn't think it matters, because it does. It's about a 60-yard difference in expected scoring (i.e. 110 in the rough = 170 in the fairway).Meant something different if he just meant he doesn't aim away from areas that are just rough or something. It doesn't change his strategy for the hole like a bunker, a penalty area, etc. might.

I’m surprised at the iron averages shown.
I am as well, Pat. But also… caddies lie and flash the wrong info, sometimes, too.  :)

Tom,


I’d rather not offer clarification, mostly because I don’t have any way of doing so. The use of those two quotes were meant to stoke conversation about golf architecture.


That said, if I were to venture a guess at how the person who tweeted those quotes would respond, it would be that the statistical relevance of angles or sides of fairways was insignificant. I can’t be sure obviously.


As a someone that still wonders exactly *why* hole is good vs a hole that isn’t, even though I’m pretty good at identifying *whether* a hole is good or not, I found the quotes extremely unnerving.

We’re splitting hairs here. Getting better is getting better. I’ve known people with hands of gold that couldn’t fly an airplane. I’ve also known people with mediocre physical skills that were gods of the sky. Or to put it in golf terms, there aren’t pictures next to the scores. Analytics is a way to understand how golfers score, and in turn, help build a roadmap on the places I need to spend more time practicing.

Saying angles don't matter and using average tour player scores as justification for the statement doesn't make sense to me.
Below is s very simplistic hypothetical way of refuting that approach using two holes that might have the same stroke average:


1) this concave golf hole averages 4.1, long, narrow, tree lined, its all about execution approach to design. The range of scores is tight, some birdies, a few more bogeys, and mostly pars leads to the average of 4.1.


2) this convex hole averages 4.1 as well. Wide with a severely crowned green and fairway with cenetline hazards and enough slope that tee shots run away from the center line. pin right and tee shot right results in an approach that a player attacks and brings birdie into play. Similar when pin is on left.  Players are more aggressive because it's a wide hole, but the convex nature of the hole has balls running away from targets so misses are punished a little more and not contained by rough or trees, and misses to the wrong side of the green brings short shots to a target that is running away from the player.


These holes have the same stroke average, the former has a tighter score dispersion, the latter more birdies but more others too. The stats say angels don't matter because a wide hole designed around angles has the same average score as a narrow penal hole designed with player execution in mind.  But do stats really describe the architecture and related strategy?

A few posters in this thread need to look up the term “gambling” and “risk”.


Descriptive statistics help ameliorate risk. Using them to dictate your approach IS a strategy. Deviating from the statistically best play is what we call “gambling”


The word gamble in and of itself implies failure.


Is not successful golf reducing the amount of/effect of those failures?


The last kick-in birdie I had was because I put my shot dispersion to the fattest part of the green and hit a 15 yard pull. It was on a Raynor Road Hole.

You've missed the parts where we've talked about average players. They actually score slightly better from the "worse" angles than they do from the "best" angles.

Don, you can "prove" anything when you're just allowed to make up whatever you want.

Variance got in my way favorably that day.
Dustin Johnson was once asked about a 9I or something he hit to two feet on the 17th hole to (help him) win a tournament. His answer, flatly in the DJ way, was "I pulled it." He paused then said "I was aiming 15 feet right of that. I wasn't trying to go at that pin."

Once in a playing lesson I talked through my shot. 150 or so, chippy 8I, aimed 25 feet left because the hole was cut on a small portion of a quasi-island type green (not water around, but 10' slopes all around). I said "if I hit it, I'll have a look at birdie. Pull it and I'll have to work a bit, but I can make a two-putt par. Push it and I might get it close accidentally." I hit it, immediately said "yep, I pushed it." It went in the hole for a 2. The least exciting eagle in history because both of us knew, and I called it right after contact, that I'd "missed" the shot I was trying to hit.

But saying angles don't matter isn't really applicable to those of us who play differently and aren't trying to post a number. It's my opinion that angles do matter to some players, to others they don't. Even if only they add interest to the round.

I like this Don. My own opinion is somewhat nuanced. I found the quotes by Lou Stagner to be staggeringly devoid of context. Social media and generalized statistics both share that commonality I suppose. That said, I’m still going to use generalized golfer analytics to make better decisions on course. So in that way, they are very useful.


My biggest take away in how this discussion applies to architecture: as these sorts of analytics become more mainstream knowledge, architects are going to have to get more creative in how they create temptation and poor choices from golfers.

Post by: Don Mahaffey on February 10, 2023, 12:56:29 PM
Ben, the problem with analytics is they create as many questions as answers.
I was talking to an MLB catcher earlier this week. He said they certainly know the history on every hitter, especially vets with 1000s of at bats.  But, they still use human scouts who are tracking the last 25 or 50 at bats as there are short term, and long term tendencies. MLB hitters mess with their swing just as much as golfers and are also always trying to adjust to how they are pitched. 
A client of mine, very much into numbers as a finance guy, told me the tour stats show PGA players make 8 footers for par more often than 8 footers for birdie. Why? He said the same reason human investors ride their losers and sell their winners.  Why? Because they are human.


Erik keeps going back to scores. Why do average players score worse from the good angle vs the bad? I think his point is there is no such thing as a good angle.  I think it might be because they are not robots and get tempted into trying more aggressive shots.  But who really knows.

Along the lines of Don's post, I'd be curious of the methodology of how the data is actually captured.

If I play a difficult par 4 with an otherwise flat fairway, but well guarded green.  The correct side of the fairway could vary significantly from day if the pin is tucked on the far left one day, and the far right the next. 

Are the data collectors for "average joes" following behind every round and taking note of things like this?

P.S Does it also factor in stuff like weather conditions, because depending on the wind direction, the "correct" side (on paper) could very well be the wrong side.  Or preferred ball flight shape?  (I can't hit a draw to save my life)

When corses are soft angles don’t matter. Once they get firm they can matter a lot.


Jim ~  I agree, and hitting PW versus 6 iron makes a big difference, too.  That is the general tone of some posts after yours.
The imponderable is really the psychological effect on many players of having a straight look at the pin versus carrying a bunker or other challenging feature such as a nob or a barranca etc.

Again, the stats are pretty consistent up to 20 handicappers. And even PGA Tour players have a dispersion pattern that's wider than many seem to think.

But saying angles don't matter isn't really applicable to those of us who play differently and aren't trying to post a number.
That's why I said this:
Except when the ball is rolling. Or if you're just looking at what makes golf interesting to you. It's important to understand that this is generalized data and the data speaks to scoring, not engagement, or fun, or interest, etc.
It's my opinion that angles do matter to some players, to others they don't. Even if only they add interest to the round. I don't think there is any reason to be shitty about it in the way you respond to people who may have a different POV.
Wow, okay there man. Hypotheticals are pointless IMO. You can make up whatever you want to support whatever position you want.

My biggest take away in how this discussion applies to architecture: as these sorts of analytics become more mainstream knowledge, architects are going to have to get more creative in how they create temptation and poor choices from golfers.
Yes, this. They're going to have to, like TD did, create things where what appears to be the optimal target may not be. They'll have it easiest working around the paint-by-numbers approach (DECADE), less so when players take more factors into consideration.

A client of mine, very much into numbers as a finance guy, told me the tour stats show PGA players make 8 footers for par more often than 8 footers for birdie. Why? He said the same reason human investors ride their losers and sell their winners.  Why? Because they are human.
This has also been shown to be misleading. When you adjust for first-putt or second-putt differences, the gap narrows substantially.

Why do average players score worse from the good angle vs the bad?
Because they take on more when they feel they have a good angle. And when they have a bad one, they play more conservatively, which is probably how they should play regardless of their angle.

If I play a difficult par 4 with an otherwise flat fairway, but well guarded green.  The correct side of the fairway could vary significantly from day if the pin is tucked on the far left one day, and the far right the next.
Lou has explained it, as have the others who have done this. The "good angle" is generally the left side of the fairway to a hole location on the right or vice versa.

Are the data collectors for "average joes" following behind every round and taking note of things like this?
Unnecessary. Arccos knows where their shots are hit from. They know where the boundaries of the fairway are, and where the holes are cut. So, effectively, yes they have data collectors noting the specifics of every shot.

Re the par vs birdie putt, we talked about that and while obviously if it’s a three putt situation the player has had a look, if he was long, at the break. But even tho the gap closes, it doesn’t CLOSE completely. It is still a fact that more putts are made for par than for birdie. Explain it away anyway you want but it seems a matter of motivation. Players are not robots and they are very bogey adverse. I’ve watched it for three years at a venue I know well, including taking the greens readings for the event. As players started to see where others made a “number” they got more and more conservative.  My takeaway was as much as they want to make birdies, most of them hate making bogeys even more. 


Re the average player being tempted to try something he shouldn’t because he’s in a good spot, isn’t that the kind of golf courses we want? Isn’t that thrill what we all want?  Do we really want to reduce the golf we play into being as conservative as possible in order to always try and avoid the big number?  Isn't that temptation at the root of good design?

It's a pretty fascinating discussion and it can bring out some strong opinions. It leaves me wondering, a little bit, if "angles don't matter" means two different thing to two different groups of people. I have some problems with the statement as made, more on that in a minute.


But Don said about strategic courses:

isn’t that the kind of golf courses we want?


I think the answer is yes! Please keep doing your best in this area, it is most appreciated! Whether it affects my score a lot may be in question, but it definitely affects my enjoyment a lot.




My questions about the analytics point of view doesn't have anything to do with their earnest desire and work to help people play better. First, still, is that I don't think most courses have much strategic value to them, so saying that angles don't matter because of stats is just a tautology. If someone told me 90+% of courses had no discernable strategy whatsoever, nothing in my experience would contradict that. In other words, there's no point in measuring strategy when none was intended. If that's true, real, intentional strategy of the type advocated here would just be a blip in the statistics at best.


Additionally, I'm curious how much the arccos people have considered the z-axis in their calculations, but I admit it's a minor point.

The statistics do not nearly matter as much as the course that presents itself to them.

It becomes almost negligible, and you're still not accounting for other factors besides "loss aversion" or whatever. When they're hitting a par putt, for example, they have seen more putts to that hole.

It is still a fact that more putts are made for par than for birdie. Explain it away anyway you want but it seems a matter of motivation.

So the flag on the right, you don't think it's generally advantageous to be coming into that from the left side of the fairway over the right side? Generally speaking?

I'd strongly disagree.

I'm probably exaggerating the numbers a bit, but the types of courses I've played most of my golf on really haven't had much to them. The small number of courses where the angles have mattered were always the most engaging to me. My preference for the latter is large, even if the scoring difference may not be.

The article examines the misses of Tour players through ShotLink data. They tested to see if there was a bias by Tour players in the direction of their misses (left or right) and found none. What they did find, however, were three major points:  Tour players miss birdie putts short of the cup a higher percentage of the time than on par-or-worse putts.

This might be a little off the wall, but here goes. In the NBA some have bemoaned the effect analytics have had by prejudicing the 3-point shot. An article I read suggested that the older style of play could be encouraged by changing the rules to move the 3-point line. I wonder what effect a rule change like a shorter, spinnier ball would have on this whole thing?

Post by: Jason Topp on February 10, 2023, 04:46:32 PM
If accurate, this data undermines the fundamental concept underlying strategic design - tempt a hazard to gain an advantage.


That may be true, but I don't think it necessarily is true. Someone has already brought up the idea that being on the wrong side may result in more conservative play, which is often the correct play anyway. Additionally there is the possibility that most courses (even those played by the pros) are only really loosely strategic at best. And finally, there is the conditioning. All added up, they blunt the effects as far as I'm concerned, and don't take away the efficacy of truly strategic design.


It might mean that we need to alter the types of hazards and features we use in order to influence play. Rough and sand don't really force the player to hit lower-trajectory shots, maybe more use of severe contours or trees would help force lower shots, especially on better players.


Charlie - the other aspect of the analysis is that even the best players in the world will scatter tee shots in a 65 yard area left to right.  The idea is that the penalty of not being in play is severe enough you need to aim far enough away from trouble to make sure the penalty will not come into play.  The cost of a full shot eliminates any advantage that might accrue from having a better angle at a particular green.   I find the analysis compelling even though I do not like it.

This stuff isn't even on topic.

Erik, on tour, more putts are made for par than for birdie.  It’s a fact. They are not robots.   They don’t all play the same no matter the circumstance.
I haven't denied that. I have shown data that very little of the already small difference is due to "human nature" or loss aversion or whatever. That very little of an already small difference is due to this:

A client of mine, very much into numbers as a finance guy, told me the tour stats show PGA players make 8 footers for par more often than 8 footers for birdie. Why? He said the same reason human investors ride their losers and sell their winners.  Why? Because they are human.

Rob, bad choice.

Quote
This past season, PGA Tour players made an average of 39.8 percent of their birdie putts from 5-to-15 feet while making 52.6 percent of their par-or-worse putts from the same distance. That means that Tour players make a higher percentage of par-or-worse putts than they make birdie putts from the same distance.

I shouldn't have to explain why that's a horrible way to try to look at this sort of thing. FIVE TO FIFTEEN FEET? I'd wager everyone's house here that the distribution of the par putts was closer to the five foot end of the range than the distribution of the birdie putts. Five to fifteen feet is a volatile range… and so even a small difference in the distribution can change the average make rate significantly.

The 2011 study made no adjustments for first or second putts or anything else, really. You could have also cited some of the more recent studies (newer than 2011). Ones that make adjustments that have nothing to do with the score of the resulting putt or ones that don't rely on comparing ten-foot wide ranges with unknown distributions of putts. Or you could have cited Broadie's book, which says:

Quote
Even though 11,000 putts might sound like a lot, it represents less than 1% of the putting data in the ShotLink database. Devin Pope and Maurice Schweitzer [the 2011 study] analyzed the ShotLink data for the par-birdie effect. In their 2011 American Economic Review article, they concluded that “professional golfers hit birdie putts less accurately than they hit otherwise similar par putts.” In 2011, I asked Mark Calcavecchia about the effect and he said, “It’s just human nature.” [Like Don contends.] Intrigued by these results, I looked into the data myself. Sure enough, for putts between four and seven feet, pros sink 3.6% more par putts than birdie putts. But that figure doesn’t take into consideration that par putts in this range tend to be second putts, while birdie putts tend to be first putts. We already know that second putts are easier than first putts because of the learning effect.

After controlling for first-putt–second-putt differences, and controlling for uphill, downhill, and sidehill differences, the par-birdie effect is reduced by more than half. Looking at all putt distances, taking into account differences in strokes gained (not just the one-putt probabilities) and the frequency of putts, I calculate an effect of 0.1 strokes per round. But even this computation overestimates the birdie-par effect. A short first putt for par can happen after chipping from off the green, so the golfer gets to see the path of the chip before hitting his putt. Before putting, a golfer often gets to see the putts of other golfers in the group putting along a similar line.

It seems likely that the par-birdie effect is less than 0.1 strokes per round. Far more important, in my estimation, is the performance increase to be gained from going to school. Watch your putts and the putts of others in your group and read the contours of the green, especially near the hole.

This behavior has become all too common, especially on social media; make a broad claim, one that may buck long standing commonly held beliefs, but provide little context as to how or why the claim may be true. Generate interest and attention but do little to support the claim.

I appreciate that Erik's commonly used narrative, "Angles matter when the ball is rolling" is slightly more descriptive, but still lacking support.

Outside of a very very few number of shots, at some point of time during a ball's travel,  the ball will roll, even if it is only for a few inches. So that would imply that angles matter on almost all shots. Beyond the exceptional few where  the ball is flown into the hole directly, lands in water or some other hazard that deadens movement upon impact, or gets stuck in a tree.

Of course this is probably not what Erik is trying to say, but without proper context and support how can we be sure?
A better, more comprehensive, pair of statements may be something like:

At least with statements such as these there are specific & measurable factors in play that can be property considered and qualified when discussing the impact of angles on any given shot for any given player.

During the numerous times this topic has been discussed on this site I've seen inferences to data and the study on the subject, but I don't think I've ever seen direct references to the actual measured data or to published studies on the subject. Thus the question behind context supporting the claim.

While we have all seen PGA Tour pros fly balls that land on greens and stop on a dime, we've also seen PGA Tour pros hit shots that land and run well away from their intended target. If one shot's landing characteristic minimizes the impact of the approach angle and the other shot heightens the impact of the approach angle, there is a basis for greater discussion on the subject. Potentially an excellent case for study is the different setups of Muirfield Village for the Workday and Memorial held in back to back weeks during 2020. Same course, but the change in setup from one week to another presented a dramatically different challenge to the players.

Did the change in course conditions between the two weeks lead to approach angle having a greater impact on scoring in week 2 vs. week 1? If so, what factors in the course setup contributed the most in that change of impact?

So that would imply that angles matter on almost all shots." Yeah, cuz that's what people are talking about when they cite the Presidents Cup at Royal Melbourne. That's what people are saying when they're talking about balls rolling. A few inches. Sheesh.

The "measured data" is often proprietary, whether it's ShotLink data that only a few people are given access to, or data from the likes of Arccos, ShotScope, GolfMetrics, etc. There's no "published study" because it's just published data. Lou can post a chart. Mark can post information. Scott can post information. I can post what I see. These aren't scientific papers with a hypothesis and a test and a conclusion. It's a heap of data that's interpreted.

What kind of "published study" do you need to see if someone says "PGA Tour players make 50% of their putts from 8'2"?" That's not something you write a paper about. It's a statistic. The stats that show that angles don't matter (and that there's often a very, very small advantage in scoring to being on the "bad" angle) are out there, and the means by which they're determined are out there. I've shared them, Lou has shared them, etc.

Here's a podcast talking about this one specifically, and dealing with average golfers (not Tour players): https://podcasts.apple.com/us/podcast/is-there-such-a-thing-as-a-good-angle/id1543363295?i=1000596708327 (https://podcasts.apple.com/us/podcast/is-there-such-a-thing-as-a-good-angle/id1543363295?i=1000596708327) or https://overcast.fm/+mucWG_TXE (https://overcast.fm/+mucWG_TXE).

If you disagree with the interpretation, then find the holes or flaws if there are any. And I welcome that challenge, as I enjoy being told "you're wrong" if the person can tell me why. "Ha!" you say? Then it goes to show how very little you know of me. Being told "you're wrong and here's why" is what I call an instant opportunity to upgrade my knowledge. Being told "yeah, I think you're right" doesn't do anything for me. I wouldn't be saying it if I didn't think I was probably right. Being told "you're wrong, here's why" is awesome. It just doesn't happen too often.

If one shot's landing characteristic minimizes the impact of the approach angle and the other shot heightens the impact of the approach angle, there is a basis for greater discussion on the subject.
Hence… me saying "angles matter when the ball is rolling." Angles don't matter when you fly it and stop it relatively close to where it lands. I've further said that this is for shooting the lowest score, on average, not for interest, or challenge, or art, or show, or whatever. I've also said it's generalized data, and when talking about specifics (players, shots, etc.) there are exceptions.

I've talked with my daughter about angles. She's playing college golf, but she's also 5' tall. Pound for pound or inch for inch she hits it really far, but… that means she's hitting a hybrid into a par four a few times a round. Angles matter to her… because her ball is bouncing/rolling.

Show me where I'm wrong, and don't use anecdata or hypotheticals or exceptions.

Look, I’m with Erik: Angles matter a lot less than we - especially on this website - would like to think.


That doesn’t mean we should stop trying to make a difference to golf course strategy using angles. Because when they do make a difference, it really does add to the game.

It sounds to me that Eric is saying angles do matter? We can talk about the whos, whens and whys, but it is very clear and obvious that angles matter.

I guess the inference of angles don't matter was a nudge to archies to forget about angles when designing courses? It's hard to imagine how much interest would be stripped out of the game if archies followed that nudge.

My issue with big data on this issue is that it's pooling over very different types of golf holes and giving an average 'effect' when there could be some interesting heterogeneity for holes that are designed different ways. I'd suspect that angles matter more for holes which are designed for angles to matter than ones which aren't.

Arccos' data come from at least tens of thousands of shots over at least thousands of different holes. Maybe the people who use Arccos play better courses on average than the average golfer, but I'd imagine that the average hole isn't setting up too stark a difference in angle from one part of the fairway vs. the other.

But would the results look the same for a sample of holes like the 8th at Pacific Dunes or the 10th at Riviera, where the green is narrow and angled toward one side of the fairway? Maybe not. But it's a strong hypothesis that angles would matter more with this type of architecture and I haven't seen an attempt to address it in Lou Stagner's many Twitter posts. To be fair, it'd be hard to test because you'd have to figure out a way to code holes for architecture.

My suggestion to Arccos would be to run an experiment, or at least half of one. You have the control group data for results from good/bad angles on the sort-of average hole. Now put a bunch of players on the good/bad side of the fairway on holes where a group of experts agree that the design of the hole makes angles more relevant. Do you get the same result? I don't know. But I haven't seen any data so far that convince me that we have evidence that angles don't matter in such a situation...although admittedly I haven't dug around for it.

Yeah… it adds visually, it makes people think, it tempts people… and there are ways to kinda throw a wrench into the system for some guys.

I understand it can be tough to play the angles thing with doglegs, etc. but maybe there's something to that… and a different sort of angles. Angles off the tee, because a drive tends to roll out some (unless it's really soft). Force people to try to work the ball or risk running through the fairway? (The difficulty being not everyone hits it the same distance, so that can be tough.)

It sounds to me that Eric is saying angles do matter? We can talk about the whos, whens and whys, but it is very clear and obvious that angles matter.
When the ball rolls, which it does for a LOT of golfers, even very good ones (my daughter got down to a + index competitively for a few months, and is still a 1 or so).

It's like 600 million, I think. ;) (Not all approach shots of course.)

Yes, unless you're just talking about a specific hole, in which case you either basically have PGA Tour data with a few hundred or thousand shots depending on how long the tournament has been there, or you have to hope you pick a popular golf course to get into the hundreds of shots to make it statistically valid.

My suggestion to Arccos would be to run an experiment, or at least half of one. You have the control group data for results from good/bad angles on the sort-of average hole. Now put a bunch of players on the good/bad side of the fairway on holes where a group of experts agree that the design of the hole makes angles more relevant. Do you get the same result?

I agree that might be interesting. Again, most of the "angles" stuff, because right now it's one of the few ways to do it, has to do with just saying "the flag is within six yards of the right or left edge of the green."

Lou has done some case studies on some specific holes, as have I for some holes. The data is often smaller, and perhaps I chose poor examples (one I chose had a huge/deep greenside bunker guarding the front right, making the left side a "better angle") and… results were basically the same until you got to the higher handicappers, likely because… they could thin the ball or top it or something and it might roll onto the green from the left side, while better players were hitting over the bunker from either side.

Full day of teaching. Have a good day. Even Ben, who is still probably trying to figure out how 18 yards became 35…

I’m confused.  If strategy doesn’t matter, how do Erik or Lou make money talking about it?  Just hit driver everywhere, and aim well away from the o.b. or water.


Oh, it’s more complicated than that?  Well, so is design.


The most important thing to understand is that architects don’t (or shouldn’t) care what score you shoot.  It’s our job to make the playing field interesting.  Most of that is about visual presentation:  we have no control over where you hit your ball, but we can try to influence where you aim.


If you want to make the game boring and calculate the optimally safe route to save 0.1 strokes per hole, instead of taking on the challenges we present, that’s totally on you.  But that doesn’t mean I’m going to stop putting them out there.

I played Riviera with your friend Norm Klopardra (Tom, I hope I have the spelling right). Btw, you set the game up!

On the 10th tee, he spent a few minutes talking about the hole design. He finished by explaining why you should never hit driver on the 10th. It was so effective that I laid up. I think my playing partners, Mark and Tom, played positionally too. He was really convincing. Norm went last, hit driver and made an awful looking six by going right. We were perplexed about why he didn't follow his own advice about percentages and strategy (taking the major risk out of the hole).

He explained that every once "he can't help himself" and will hit driver.


As a general thought, some play percentages and some love risk (that's me). Most are flexible. They take chances based upon the feeling of the moment. Feelings matter. The reward of overcoming something challenging is one of golf's "stickiest" attributes. It provides a rush that we don't get from simple execution. Angles matter because its an opportunity to overcome a risk.

If golf was simply "bowling" with all the trouble at the sides and strictly about execution, I wouldn't play the game. It's not enough for me. I need to roll the bones every once and a while and feel the thrill of making the carry.

Erik points to an interesting point when he mentions angles of the tee and doglegs. A dogleg creates a different kind of angle than hazards around a green. I do not know what that stats say, but it seems intuitive that if you end up with a longer second or third shot because you ended up on the side away from the dogleg, your score likely is to affected.


One of the reasons that I like centerline bunkers is that they create multiple options off of tee that consist of different angles. When well done, they also can present a risk reward dilemma even for longer hitters. Plus for those hitters, a centerline bunker minimizes the ability to just play away from trouble.

I think Brett did a nice job laying out many of the issue I have.

Actually "proving" that Angles actually don't matter is a very difficult to thing to do given the near endless variables at play:

Length of hole, size of green, undulation of green, amount of bunkers and where their positioned, fairway width, depth of bunkers, rough height, fairway height, length of approach, type of grass, weather conditions, strengths and preferences of golfers, etc, etc, etc,

The burden of proof lies with those making the claims, to clearly and succinctly lay out the methodology, controls, processes, and data to arrive at said conclusion, not with others to disprove the hypothesis.

The Sagan Standard could certainly be applied here: "extraordinary claims require extraordinary evidence"

Thing is… it's really not much more complicated than that, no. I'm sure design is WAY more complicated than strategy. Just figuring out how to drain water is probably an order of magnitude more difficult.

Doing that doesn't make the game boring. You've still gotta hit the shots. You've still got four hours outside with your buddies. You've still got a beautiful golf course to look at.

On the 10th tee, he spent a few minutes talking about the hole design. He finished by explaining why you should never hit driver on the 10th. It was so effective that I laid up.
Laying up is generally not the best strategy there.

I do not know what that stats say, but it seems intuitive that if you end up with a longer second or third shot because you ended up on the side away from the dogleg, your score likely is to affected.
Naturally, yes.

When I think of doglegs, for example… the 17th at Pine Needles. even if you carry the left-hand bunker, it can be tough to stop your ball from rolling through into the trees on the right. Play right of the bunker, and you leave yourself a really long approach.

I said something earlier about data analytics (for the avg golfer) becoming mainstream enough that it changes what architects do to provide interest, tempt, or confuse. This quote makes me feel a better about how that will work out going forward.
That, and the fact that this "statistical driven strategy" stuff is only ever really known to a tiny percentage of golfers. Heck, everyone here is a golf nerd, and most of y'all don't believe me.  :)  So, there are always going to be plenty of people who think angles matter in times when they really don't (for scoring, not for interest/whatever), etc.  :D
This thread has been enormously informative from a number of perspectives. I can’t imagine a world where I’d stop playing golf to have fun. Shooting better scores is part of that, but taking on and succeeding against poor odds is a bigger part of what makes golf great.
Golf is still ridiculously difficult. You're ALWAYS battling poor odds, even if you have a "perfect" strategy. I reject out of hand the notion that playing strategically makes golf "less fun."

I like to use Tobacco Road as an example. You can play it a number of ways. You can go after everything, letting yourself get baited into going for every dumb shot out there. You can shoot 83, but pull off ONE of those shots, and you remember that. And if you enjoy golf that way, cool! Great. I'm glad, as ultimately… do what you want. Do what makes you happy.

What makes me happy is deciphering how best to play the hole, then pulling off the shots to do so. A "boring" 69 at Tobacco Road is more interesting to me and more fun for me than a 78 where I go for everything even though I know it's the "wrong" play.

Golf is still plenty hard enough. You've still gotta hit good shots.

The idea that the tour players have a lower score from the "wrong" side is really eye opening. Kind of reminds me of Jack Nicklaus playing the safe shot , almost never flag hunting unless it perfectly fit his shape. This despite having more talent than almost anyone who ever lived!

Thanks for posting this Erik. I did what you said and played around with the 10th hole at Riviera.

But first of all, Stagner's post above about the 10th hole at Riviera didn't address the issue of angles at all. He compared layups to attempts at the green. To test whether angles matter, you'd want to compare average scores for those in the left side of the fairway vs. those in the right side of the fairway, maybe just to pins on the right half of the green. If scores are lower from the left side, that's some evidence that angles matter.

To test this, I subsetted the Riviera data to shots under 250 yards to pins on the right half of the green (pins 3 and 4). Here's what that looks like:

(https://live.staticflickr.com/65535/52683500852_a62565294f_c.jpg) (https://flic.kr/p/2ogsHkA)

What I'd really want to do is see the average score for those left of pin placement 2 vs. those to the right of it. It doesn't look like I can do that. But using the eyeball test, it looks to me like there might be a few more birdies and a few fewer bogeys relative to pars left of that line vs. right of it. I suspect that the scoring from left of the line is slightly lower than from right of the line, but maybe not a huge difference.

But that raises another issue that I have with using big data: even if the scores from the left half of the fairway here were lower than from the right have, that still would be a bit lacking as evidence for my angles theory. Why? Because there's a good chance that players who hit it in the right side of the fairway were playing worse than those who hit it in the left half of the fairway. I don't think that anyone would intentionally aim at the right side of the fairway here if laying up. So our 'effect' of angles might be polluted by an effect of playing worse.

One way to help address this would be to control for the player's scoring or, better yet, strokes-gained driving to this point in the round and maybe even for a broader set of recent rounds. Now Arccos has this data and they could do this test. I'm sure they do this type of analysis in other scenarios. They should do it here too and Lou Stagner should post some of that on Twitter, or maybe in a Substack.

Ultimately the problem with big data is that if you have any type of bias in the data generating process, you can get very misleading results. Arccos has the data to address some of this with more sophisticated data analysis. But you can't get around the fundamental fact that different trending players are playing from the good/bad side of the fairway and that you don't have as many of the good-trending players playing from the bad side and the bad-trending players playing from the good side. So angles aside, you're likely not getting a second shot of the same quality from those on the good side vs. the bad side and ultimately there's no way to control for that...meaning that you really need an experiment to test this.

But first of all, Stagner's post above about the 10th hole at Riviera didn't address the issue of angles at all. He compared layups to attempts at the green.
It's also a shot where, for those who lay up, they're hitting a very short club off the tee. They can "chase" the angle a little bit, and the green is so shallow and tilted, it's almost likely to be a bit of an exception.

Why? Because there's a good chance that players who hit it in the right side of the fairway were playing worse than those who hit it in the left half of the fairway. I don't think that anyone would intentionally aim at the right side of the fairway here if laying up.
Also correct. Lou says in the podcast that players actually score best from the middle of the fairway, and my initial though to that is that those players are simply playing better that day, too, overall (perhaps).

So, yes, these are just interpretations of the data, as I've said. There's no "peer-reviewed study" to be done here. Question or poke at the data, but it just says what it says.

Post by: Jeff_Brauer on February 13, 2023, 02:12:07 PM
.........If accurate, this data undermines the fundamental concept underlying strategic design - tempt a hazard to gain an advantage..... 


My take on this is that some of the old guys wrote that in their books (which they may have believed, but the books were mostly for marketing) but there really was never any "proof of concept."  100+ years later, modern statistics allow that to happen.


I don't challenge fw hazards often (there is no rule that is absolute, of course) as a relatively straight driving average golfer.  Neither do most ams.


None of the tour pros I have worked with did, nor club pros, nor top ams, nor average players.  When asked which side of a fw they would aim for in designing or redesigning a hole most said, "The middle."  Jim Colbert (a grinder who tried to hit the shot required rather than play his stock shot pattern) often preferred to come in from the side of the greenside hazard.  He reasoned it was like teeing off with OB on one side, i.e., that you double the safety angle by aiming away from the hazard compared to coming in from the open front side.  I have heard Jack Nicklaus say the key to playing a hole was to miss the fw hazards.


Sure, there are holes where it really matters, but like most public discussions, the discussion seems to lean towards the exceptions, not the middle ground.  In reality, challenging a player on the tee with temptation probably only works on par 5 holes where a true full stroke might be gained and/or perhaps a hole late in the round where a gamble might allow them to a last ditch effort to catch up to an opponent.


I don't even think those Golden Age designers thought about it and applied it religiously.  After all, if they did, would there be such a percentage of greens from that (or any other era) with what Colt called "wing bunkers" both right and left at the green?  Bunker left, bunker right hardly seems strategic, unless staggered front and back.


Ross wrote, "There is the hole. Play it any way you please."  The first Masters program with the article "by Bobby Jones" was really written by MacKenzie, and people I trust have told me there is a radio interview with Jones where he said, "Mac wrote that, but if there is a hazard, I play as far away from it as possible to avoid it."  I can't recall Colt's writings, other than the wing bunkers I already mentioned.


On the other hand, there isn't much new in those stats, just things most folks knew and are very refined. We know that tour pros miss 50% at 8 feet, but that even at 100 yards, the average distance to the flag is 19.5 feet.  Aiming at the tucked flag has been shown statistically to be a loser, i.e., why risk hazards to possibly gain a 50% chance of birdie?  Then, statistically, the number of made putts from 15-50 feet is about 0.1% difference, so please aim at the fattest and deepest part of the green.  Jack, Tiger, and the other top players stood out with what would be called "course management" which is really code for missing hazards.


The same has always been touted for ams (i.e., aim for the fat part of the green) because they have similarly consistent shot dispersions, albeit at greater angles.  If tour pros are about 13% (6.5 yards on either side for a 100 yard shot) then ams must be about 25% (I don't recall that offhand, but could look it up.)  As pros have taught for years, ams are nearly always better off playing to the safest area possible.


As to what that all may mean for design, I don't know.  Talking with those who support this system and design courses, they don't say they design greens much differently, following the land and using aesthetics as the basic principles.  Where angles do matter is on the tee shot, as when Pete Dye alternated left and right angled fairways.....but that was to encourage or reward a certain shot type, not necessarily to set up an angle.  I believe most tee shots should be designed the same way to test various skills.


Basically, your score is 90-95+% skill and/or execution, and at best <5-10% strategy.  Of course, aiming at the biggest targets is a strategy in itself, perhaps cloaked as course management.  As many have mentioned, when you factor in how you are playing that day, wind, conditions, roll, etc., strategy has always been more about nuance than the simplistic idea of trying to hit a target that gives you and open front green.


And, if my understanding is correct, the best way to create strategy is to undulate at 3-5% fairways in the 300-350 range, since hitting off different fw lies makes golfers create a shot that is different each time.  Those same undulations in shallow rough really complicate things for better players and are probably the best investment in toughening the course for them, vs more expensive sand bunkers only 1% of golfers will find.


We had Scott Fawcette at our ASGCA winter meeting and the reaction from our members was about as miffed as the reactions from those here.  Some of us also looked at those Stagner stats, and the reaction was similarly miffed or confused.


And, as always, just MHO.

I wonder if folks truly understand angles. To say they don't matter is to say you aren't paying attention. I just played a course where angles mattered a ton. Not only for a safer angle of approach, but also the likely leave if one didn't execute from the poor angle. This wasn't a few holes. It was hole after hole. Sometimes better angles could be achieved by the ability to hit a long ball.

I gotta ask. Do people not play in wind or on even moderately keen turf? Do people all bomb it 300 yards and hit towering irons with crisp precision? If so, it's a game I don't get to play nor often witness. I am often merely trying to get on the green, so yer damn right angles matter. There were at least 10 times yesterday where after my tee shot, angle position mattered significantly. At least 8 drives where trying to get in the right area of the fairway mattered because of angles...and none involved bunkers.

I wonder if folks truly understand angles. To say they don't matter is to say you aren't paying attention. I just played a course where angles mattered a ton. Not only for a safer angle of approach, but also the likely leave if one didn't execute from the poor angle. This wasn't a few holes. It was hole after hole. Sometimes better angles could be achieved by the ability to hit a long ball.

I gotta ask. Do people not play in wind or on even moderately keen turf? Do people all bomb it 300 yards and hit towering irons with crisp precision? If so, it's a game I don't get to play nor often witness. I am often merely trying to get on the green, so yer damn right angles matter. There were at least 10 times yesterday where after my tee shot, angle position mattered significantly. At least 8 drives where trying to get in the right area of the fairway mattered because of angles...and none involved bunkers.

Even anecodotally, the situations you were in v. the situations you think you would have been in are not likely that statistically different when it comes to scoring. That's why "angles don't matter."

How many "bad days on the golf course" were because you played from all the wrong angles? How many "good days on the golf course" were because you played from all the correct ones?

Avoid double bogeys and penalty strokes. That's it.

I couldn't disagree more. Getting the right angle for up and downs etc can make a big difference in increasing odds to lower the score. Getting the right angle to hit low shots with less wind effect can make a big difference in increasing odds to score lower. To me these are obvious facts.

I raised the question before, how much interest in the game would be lost if archies didn't design angles? It's a question that doesn't isn't worth an answer because most know it would be significant.

Sure thing, pal. Kyle gave a better answer than I will here…

That's just missing it in the right spots. You can miss it in the right spots whether you're coming in from the right side of the fairway or hugging the fairway bunker on the left.

Isn't it --angles don't matter as much as distance?


The way I understand the Stagner/Fawcett/Barzeski/Strokes Gained approach (I'm sure there are nuances between them). You can't reliably get the best angle unless you sacrifice distance (and dispersion) and being closer outweighs almost any angle. Hit your drive as far as you can where you take hazards out of play by aiming between any hazards at your carry distance and live with the dispersion and possible bad angle. If you bring a hazard into play (within your drive dispersion) by chasing the angle the math doesn't work over the long term.


Yes, what you said above. Length is just hugely important in golf. Always has been, always will be.

You can always hit a bad shot which doesn't matter what one's intent was. But I believe my odds are lower of hitting in bad spots if I have better angles. I also believe I have higher odds of hitting good shots if I have a better angles. I also believe I have more options on shot selection if I have better angles which can potentially lower my risk. The issue of risk in earning better angles is a different queston all together. For me that depends greatly on width, keen conditions, elevation change, wind and potential risk. It isn't too often I can blow over hazards/features to earn better angles. I almost always feel a bit handcuffed on soft parkland courses because I know my shot selection is essentially limited to hitting the ball in the air regardless of wind or width. To say angles don't matter is a narrow PoV  and I know you said in certain circumstances angles do matter). I am suggesting that keen conditions are not the sole determing factor in angles ebing valuable. I know for a fact they matter to me and I know for a fact that I am not alone in this PoV. I fear far too much about how the game is played by hacks is pulled from incomplete data.

Sean,

Even in your own post you are farther down the path to "angles don't matter" than you think!

"Increasing odds" is one thing so sure, let's explore that for a second.

In order for an angle to "increase my odds to lower score" you must first:

1: Have a golf hole where there is a wide variety of angle based outcomes
2: Execute a shot to find that angle
3: Execute a shot to take advantage of that angle
4: Hole a putt


Then, and only then, will the "increased odds" actually reflect on your score in the manner of a discrete shot.


Why would I think this way when the conditions in order to meet taking advantage of the angle are so strict and MIGHT amount to one stroke over the course of a few rounds? Especially compared to understanding my dispersion pattern and making sure that I don't put that dispersion pattern in a situation that will create a penalty stroke or double-bogey.

From there my perfect shots won't get me in trouble and half of my misses would actually put me in a better position. Do that twice in a row and I've significantly increased the chase of the hole getting in the way of my ball without worrying about a single angle out there.


From a coaching perspective, why would I tell a student or golfer to go chase angles when doing so introduces a higher possibility of a much higher score to gain something that may even add up to a one shot advantage? Even in the firmest conditions, the best strategy is to make sure your dispersion pattern isn't going to get you into trouble and let variance push the hole in the way of your golf ball.

Everything else is a gamble. The gamble is what you consider fun - which is a point that I'm inclined to agree with. But the statement "angles don't matter" is not all that far from "the house always wins" in casino gambling. Long term, even the best strategies fail to pay.

This.  Statistically, playing from the supposed better angle DOESN'T affect your score by more than 0.1 strokes on average.  We don't know what conditions of those 6 million shots were measured in, but my guess is that is enough to average things out.  On a select few shots, they certainly can matter.


Maybe the title of Lou's post is misleading.  Angles do matter.  If your 99% tee shot dispersion angle is 4 degrees in both directions, the most important angle is to play 4.5 degrees away from a penalty hazard in favor of keeping it on dry land or inbounds.  The goal is to keep it in play as long as you can.


Side note to my post above, I never understood why anyone would challenge hazards with a driver to avoid challenging hazards with a 7 iron.  Maybe angles can be situationally important when hitting a fw wood in (especially in the old days) but with new clubs, what may have worked (I still don't know that it did) then just doesn't work as well now.


Besides, Mac who wrote the Masters program piece that started this entire line of thinking, also said that the goal architecturally was to tempt people to play shots outside their ability, or match their shots to their ability.  (i.e., carrying a cape bunker means nothing if you are topping your tee shot, lol).  All these stats do is give the thinking golfer a better gauge of their ability, and no surprise, it's not as good as they think they are, and if armed with this knowledge, they can make better strategic decisions.   


As to what constitutes a bad day on the golf course, in my case, it is muscle memory continuing the same bad swing even when I consciously know what I am doing wrong and trying to correct it.  :D

There is a small irony in this post because I think, deep down, a good number of smart people have realized this for a LONG time.

Tom Paul, the grandfather of this concept of Ideal Maintenance Meld, was an early proponent in his own way.

The ideal maintenance meld, of course, hinged on the idea that a well-struck golf ball should lightly dent and bounce twice before any effect of spin controlled it from...

...

...

roughly 150 yards.

The implication here is that anything within that distance is reasonably controlled to stay within a few feet of where the ball lands.

Steve Smyers once told me that the best way to challenge great players is to ask them to hit precise shots off varyingly uneven lies from various distances.

Tom Doak once wrote that the best golf holes in the world have two elements that interact with each other on subsequent shots or some such idea which I just paraphrased.

The above three points and a mountain of shot dispersion data should make it rather straight forward to continue to build compelling golf courses for the better players while still accomodating those with less skills or gifts.

Kyle,

While I think the above model works perfectly well for the very good golfer, (low single digit to scratch), I don't think it accurately accounts for the average golfer at a 15-16 cap. For players like us, getting pars are our birdies. 

going to your 4 step analysis, while Step 1-2 still hold true, I would amend it after that.

Step:

3) Execute a shot to take advantage and if you miss (the most common one being short), it'll be a less worse miss that ends up in the collar or fairway as opposed to in longer rough or a bunker.

Step 4 then becomes either:
A) Two putt for a par
B)  If you missed, be in better position to save the par, but at the very least take double or worse out of the equation and get an "easy" bogey.

In either outcome the lesser player is simply minimizing bigger scores.

Give players options. The more options they have… the more likely they are to choose the wrong one. If your choice is basically "how much of an angle do I want to play" that's one choice. And there's a mathematically sound way to approach it (regardless of whether you're playing for the lowest average score or the best chance of a birdie or something THIS one time).

While I think the above model works perfectly well for the very good golfer, (low single digit to scratch), I don't think it accurately accounts for the average golfer at a 15-16 cap. For players like us, getting pars are our birdies.
Par isn't necessarily relevant. The only real difference between a good player and a bad player is the size of the shot dispersion pattern (the size of their "Shot Zone" in my book).

Kalen,

There's a level of competence minimum here and that somewhat plays out in another arena. Ultimately that boils down to whether or not you're just trying to squeeze the best out of your round that day in a vacuum or are you attempting to improve yourself between rounds.


Assuming we have a reasonably designed golf course and the player is playing the appropriate length tees (this is a whole topic in itself under this umbrella) the majority of bogey golfers are still looking at three shots to the green on most of the holes. Do "angles" matter? Probably not as much as simply geometry and still not spending penalty shots to get there. In this case we're attempting to avoid triple bogeys and no longer chasing par. The shot dispersions are still going to dictate the target.

If the player isn't looking to get better between rounds then what's the difference between that player and the gambler looking to simply maximize a night at the Craps table? Chasing angles, for any golfer, is no more effective (while admittedly thrilling) than betting hard ways and field bets at the craps table. You're playing in to the house's hand but when it hits, it feels good!

Great. That's fine.

But let's assume we're trying to improve our games...

First, the data will show that keeping the tee shot in play and then prioritizing greens in regulation will improve you the most the quickest. And in that order. So if chasing the angles is potentially getting your tee shot out of play.... often times the RISK with risk/reward... well you get that.

Ultimately the real crux of the "angles don't matter" argument is that improving your game by chasing angles is ultimately a losing proposition and that efforts and practice elsewhere combined with an approach that ELIMINATES DOUBT is what's going to ultimately drop you score.

I don't think you'd find anyone that wouldn't admit that pulling off a low percentage shot to gain an angle is THRILLING, but I also don't think you'd find any competitor that wouldn't mind sitting across from that mindset at the poker table, either. And for the same reason. They're going to beat themselves more often than not. You may lost to someone getting luckier than you do that day. But you'll never lose because you beat yourself.

Kyle,

Thank you for that last post, that was very well thought out. I don't think we're too far off on this issue, but as with many topics on GCA, this one is certainly nuanced.

While I don't agree with the blanket statement "Angles don't matter", there are certainly other statements that are more correct.  Such as "Angles may matter a heulluva lot more on one hole that they do on another". Or that other things matter more in the form of "Angles don't matter as much as getting the ball in play or getting on the green in regulation" as you put, 100% agreed on that for sure.  But at the end of the day angles still can and do matter, it's the how much that is up for debate.

On some holes, angles can matter quite a bit, like for example #6 and #16 at Pac Dunes. Getting over to the right on 6 and the left on 16 are critically important to nearly any class of player, and especially so for golfers like me.  A heavy price will be paid, oftentimes in the form of multiple additional strokes.

Or on countless holes you may find on your local muni, where there is no particular danger to missing on either side of the fairway, why not attempt to play to the side that doesn't require a carry over a nest of bunkers, or a pond?

We could sit here and likely come up with dozens of other situational scenarios using various other criteria like blindness, weather, playing to one's strengths, length of rough, depth of bunkers, etc, but it all still points to the biggest issue in not knowing the methodology of the collection of the data.  And in absence of that, the .1 stroke differential is basically meaningless.

There is a hidden “match play v. stroke play” debate going on here.


It’s also why I don’t feel match play is of any inherently superior value to stroke play and vice versa.


When you can remove yourself from the game, and the only penalty is a discrete value of one-hole, the rewards and risks are skewed.


When you can’t remove yourself from the game, and MUST continue, the math becomes quite simpler.


I’d venture that Sean’s method or strategy or point or whatever is much less efficient in stroke play long term.


As for match play? That’s just as much about the other person teeing it up against you.


Sport v. Game


The issue with attempting to debate this with the “angles DO matter” crowd is that when they get beat or see the “angles don’t matter” crowd play well they ascribe to the mythical thing they can’t attain:


“The man was a machine off the tee, he never missed!”
“She was putting to a bucket that day!”
“Dialed in, hit so many greens”


But they fail to realize that their perception of their opponent’s play is strictly result based. Did they never miss or did they choose targets that kept their dispersion pattern from getting them in trouble? Were they actually “putting to a bucket” or did the hole get in the way more often that day because they had an unusually good variance of all the other shots?


Going back to my 15 yard pull on the Raynor Road Hole:


I was either “throwing darts” (the actual result to a foot)
“Never missed a green” I hit my target 15 yards right of the hole location but still on the green.
“Putting to a bucket” I make the subsequent 45’ putt


Or


“Routine par” but making no mistake and pushing the opportunity for any of the above comments further into the round.


All of the above are simply because I chose a target and a club that put the vast majority of my potential results away from double-bogeys. I wasn’t pin-seeking or chasing birdies. I was simply maneuvering into the next possible position to attack and caught a break within my variance of expected outcomes.


For me it was “the hole got in the way.” And nothing more.


I give all the credit to any clarity in these thoughts to Mark Broadie and Scott Fawcett. In my July 2018 interview with Ran I said that I do believe Strategy is overrated and then word vomited some explanation about that. Mark and Scott’s independent work helped congeal those thoughts into something more clear.

Sport v. Game

Matchplay didn't enter my mind, but yes, I can definitely see taking on situational risks that one wouldn't normally contemplate.

No, my point is that when you don't know the abilities of a golfer, the course, the conditions, then it isn't clever to say angles don't matter. Of course they can and do matter. I play courses where angles matter very little and some where angles can make a big difference. It happens that in winter months angles tend to be more important because there tends to be more space with rough down. Which is one reason I mentioned the round from a few days ago. There were tons of opportunities to play angles.

I think you guys are seeing angles as ways to take on risk. Angles are just as important in avoiding risk. The subject is far more complex than a simple angles don't matter statement.

Post by: Kyle Harris on February 15, 2023, 06:19:40 AM
Sean,

All abilities have a shot dispersion. Everything from there is applying the shot dispersion to the next shot. You are still more likely to get down in 3 shots from a greenside bunker you failed to carry from the "wrong angle" than you are getting down in 4 shots from the "ideal angle" 160 yards out in the fairway. Even if that's 0.1 shots more likely it still demonstrates that angles don't matter. A bogey from the "ideal angle" counts the same as a bogey from the greenside bunker.

Angles don't enter into that. That's why they don't matter. If a large chunk of your shot disperson is going to cost you a stroke becauase you are attempting to find the correct angle you are not making the correct choice long term. If a large chunk of your shot disperson is within the "correct angle" by aiming away from the same, then if angles matter you are making the correct play. Either way, you're not chasing angles - you're placing your disperson pattern in the place of least resistance.

These are unassailable facts. It's not arrogance. Ultimately, what you would classify as a poor shot or a missed shot others will classify as an example of variance costing you more than it needed to. My aiming well right of a "correct angle" but into a safe area and pulling it into the correct angle is not going cost me as much long term as aiming continuously for the "correct angle" and pulling it into a hazard every now and then.


To improve, you'd gain more long term by working on tightening your disperson pattern than you would by chasing angles.

1. Avoid penalties
2. Avoid double-bogeys
3. Get driver in play as far as possible
4. Hit GIR
5. Get close to the hole

Then. Maybe.

6. Chase angles

The problem is that most recreational golfers don't mind losing enough to ever care. Gambling is only a problem when you care about losing, but when you're winning it's a "system."

I tend to agree that "Angles Don't Matter" where the design and the conditioning don't lend themselves to the player being at an advantage by approaching the green from the right angle. Perhaps that's where Sean and Erik/Kyle differ. I don't know where Erik and Kyle play their golf but I know from experience that Sean tends to play older courses that go for a firm and fast meld and where greens are often subtly orientated to favour one side of the fairway over the other. Firm and fast often accentuates any mistakes and therefore the advantage of approaching from the "correct" side increases.


Think of a situation where the player is hitting a long iron/hybrid/fairway wood to a green on a fast and firm course. For most players the shot might call for the ball to land just short or at the front edge and then to run on. Now imagine if the green is slightly angled with offset bunkers on either side accentuating the angle then clearly being on one side of the fairway is going to present a relatively clear path relative to the other where the front of the green might be partially covered by a flanking bunker thereby significantly reducing the opening to the green. Neither is the airborne route any easier as the ball isn't going to stop quickly on landing when hitting that kind of club. In that scenario, which is by no means rare on a lot of courses over here, it's fairly obvious that angles matter.


Conversely where you have fairly soft conditions and circular greens that don't favour a particular angle of approach then I imagine angles don't really matter. What kind of courses did they take their stats from ?

Perhaps that's where Sean and Erik/Kyle differ. I don't know where Erik and Kyle play their golf but I know from experience that Sean tends to play older courses that go for a firm and fast meld and where greens are often subtly orientated to favour one side of the fairway over the other. Firm and fast often accentuates any mistakes and therefore the advantage of approaching from the "correct" side increases.


Think of a situation where the player is hitting a long iron/hybrid/fairway wood to a green on a fast and firm course. For most players the shot might call for the ball to land just short or at the front edge and then to run on. Now imagine if the green is slightly angled with offset bunkers on either side accentuating the angle then clearly being on one side of the fairway is going to present a relatively clear path relative to the other where the front of the green might be partially covered by a flanking bunker thereby significantly reducing the opening to the green. Neither is the airborne route any easier as the ball isn't going to stop quickly on landing when hitting that kind of club. In that scenario, which is by no means rare on a lot of courses over here, it's fairly obvious that angles matter.


Conversely where you have fairly soft conditions and circular greens that don't favour a particular angle of approach then I imagine angles don't really matter. What kind of courses did they take their stats from ?


Niall


Niall,

There is acknowledgement to firm and fast conditions making a difference but as far as stats are concerned they are based on shot dispersions. How the shot got to where it ended up doesn't much matter, just where it stops. I'll be the GIR rate from either side of the fairway in your hypothetical case is similar or not statistically significant. And I'll bet the bogey rate is nearly identical. What's the double-bogey rate of shrinking the target off the tee to one preferred side?


Depending on the nature of firm and fast certain features can tighten dispersions just as much separate them. If you're so fast that everything moves to the bottom of a collection area, is that really interesting? I've argued no for years. I think Jeff Warne is with me.

We have a few holes at Streamsong that see this play out where the target and angle actually does matter to some degree for all classes of player. Blue #8 is a good example, though longer hitters here are contending with a penalty shot, as well. A shorter hitter will have to play down the left as the right side will throw the ball outside of the reach of their second shot. But in playing down the left, the shorter shot is done over a forced carry all the way to the green. Does playing the extra shot on the right-hand route outweigh any inherent risk to reach the green in two down the left-hand route? Considering no penalty shots are in play here we have an actual strategic decision.


I also have numerous preferences to the side of the fairway (Streamsong Red #11 comes to mind, I much prefer being down the low left side though most caddies on the property will guide you high and right) from which I play on certain holes, but thinking in terms of shot dispersions as opposed to "ideal/unideal" has helped eliminate any DOUBT I may have in case I don't execute the way I intended and see that there truly is no penalty other than the one I created in my head.


And that's the crux of it. Searching and chasing angles more often than not CREATES problems that simply don't exist with the shotgun at the end of a shaft we employ to strike the ball. Just keep all the buck shot in play and wait until it hits the hole.


Strip away the created mental hazard and how many times during a round of golf is there a true mathematically strategic choice? Are they enough to actual worry about as a means to shoot the best score consistently?

If I understand your first paragraph correctly, you are suggesting in the scenario I described that the percentage of players playing from the "harder" side who hit the green is likely to be no different than the percentage of players  playing from the easy side, is that correct ? That's like saying that if you asked a 100 people to throw a ball into a basket from 10 feet and then asked the same 100 people to throw the ball in the basket from 5 feet that you would have the same or similar success rate both times. You may well be proved to be correct but I find it hard to believe that would be the case.

The so called exception proves my point. Blanket statements such as angles don't matter is a gross oversimplification.
It does not, because you don't even know if you score better or worse doing what you suggest. You're basically saying "angles matter because I say so." Well, cool.

And to be clear, I've been consistent in saying that I'm talking about scoring, and even then, when the ball is not rolling. If you hit the ball lower and it rolls (like my daughter), angles can matter because the stuff on the ground comes into play more. And if you like to play for angles, or find it more interesting, or something other than scoring, angles can matter to you.

An exception doesn't prove your point. There are exceptions to all kinds of things that are generally true.

Of course they can and do matter.
Geez. Do you realize how lousy an argument that is? "They matter because I say they do, and if you disagree with me, you're not paying attention." You haven't brought any facts to this argument. You haven't brought logic to the argument. You haven't brought data to the argument. You're just stating your opinion as if it's fact, with no foundation or backing.

Angles don't enter into that. That's why they don't matter. If a large chunk of your shot disperson is going to cost you a stroke becauase you are attempting to find the correct angle you are not making the correct choice long term. If a large chunk of your shot disperson is within the "correct angle" by aiming away from the same, then if angles matter you are making the correct play. Either way, you're not chasing angles - you're placing your disperson pattern in the place of least resistance.
Yep.

To improve, you'd gain more long term by working on tightening your disperson pattern than you would by chasing angles.
By FAR.

The problem is that most recreational golfers don't mind losing enough to ever care. Gambling is only a problem when you care about losing, but when you're winning it's a "system."
If golfers want to play Tobacco Road by taking on every dumb challenge offered, and they find it fun, cool. Good for them. But that doesn't mean they're making the right choices, long-term, for their best chance to score.

I'll put it another way: the stuff on the ground (bunkers, rough, creeks, slopes on greens, fall-offs, mounds, false fronts, ridges/contours, whatever) only matter when the ball is on the ground. If the ball is not on the ground much, that stuff doesn't matter (to scoring).

With regards your last post, that is more or less the point I was making. In the absence of fast & firm conditions and a design that differentiates between different angles of approach then angles probably don't matter. However there are an awful lot of classic courses out there built on the principles espoused by the likes of MacKenzie, Simpson, Colt etc where angles do.


Of course, often the choices aren't so stark as left and right but a degree of in-between.

Niall,


They matter more when the ball is rolling but not nearly as much as we’d all like to think.


I play one of the firmest and fastest and most strategic courses there is. And I learned long ago that I score best by just keeping my drives somewhere in the fairway and having a good day with the lag putting. I’d far rather be on the “wrong” side of the fairway all day long than I would on the “right” side of the fairway but with two drives ending up in a bunker because I got too cute.


EDIT: Part of the reason they matter less is because for long approaches (where the ball is naturally going to roll out more), the angle difference between the wrong and right side of the fairways is relatively small. For short approaches - where that angle difference can be much larger - most golfers don’t have to worry about significant roll on the ball.

Lousy argument? You essentially agree! You haven't come out and and said wind and terrain can be factors which can make angles more relavant, but if you thought about it like you did f&f conditions would would concede the point. What your blanket statement should read is angles don't matter except when a, b, c, d etc are present. And I never mentioned blind shots where a better angle could eliminate that situation. You guys are trying to create a odds on best play rules extrapolated from data not properly gathered to address the question. The data is fact, the created rule of play is not fact. Its a guide which is meant be just that. In no way should it be taken as an absolute fact and written in stone rule. Its fine if you want to claim that using angles is so rare that it should be discounted or isn't statistically relevant. All I am saying is I come across many situations where angles do matter. I play a lot of hilly courses in a lot of wind on firm ground. My reality is angles do matter; not always, not never. I have no idea of the percentages in terms of taking on a shot. If there is any hint of disaster lurking and I am in doubt of my abilities, my intent (if I am keeping score) is usually to play safely away from trouble and try to gain an angle of attack with a shorter, open shot, accept a longer putt or even be a bit off the green.

Mark,

Completely agreed.

It seems mitigating risk in the form of seeking out better angles of attack in hopes of avoiding bigger numbers is not a valid argument.  The only side being discussed is "improving" scores as opposed to how to decrease risk and take scores worse than par (or bogey for the everyday joe) out of play.

Logically speaking, it's a good analysis to me. I'm sure someone will explain why it's not. But for me, one reason it may not reflect in the numbers is because so few greens are designed like that. Looking at a lot of aerials, most greens describe a rough circle or an amoeba-ish square. The greens with an extreme enough shape for the effect you describe are so few in number that they don't even represent a statistical blip, even if they overwhelmingly showed that angles do matter in those specific cases.

Niall


This gets a bit self-referential.

If it is indeed the harder side then the statistics will show that it is the harder side.

The thesis isn't that harder/easier sides don't ever exist - it's that they don't exist nearly as often as players think. It is far more likely that an angle/preferred side doesn't exist and that true strategy is, in fact, rare. And even more rare where it actually impacts your score and scoring expectation.

My "feelings" as a player fit this description. I am MUCH more comfortable hitting over something or having the miss be in front of the target than I am having the miss be left or right.

The player you describe, though, would still be better served spending their time elsewhere to improve than attempting to gain some angle off the tee or approach.

I think a good little case study for this may be the 12th at Augusta National. Where's the target for that player?

Honestly, there just may not be much you can do for them on the course anyway.

I think this discussion comes down to the reasons one plays golf. 


It's pretty well established (as Erik has ardently discussed), if your only priority is to shoot the lowest possible score, angles aren't very high on the list of things that matter.  That being said most people don't play golf just to shoot the lowest possible score.  Even in club competitions I find people are more concerned with beating their friends.


I keep score in nearly every round I play but you better be sure I don't play golf to shoot the lowest score I can.  I play golf because I enjoy the way I feel when playing (even if it's a bad feeling when playing poorly) and often times I feel good when I execute something I'm trying to do that is challenging.  If I'm trying to hit the right side of the fairway and I succeed it feels better than just hitting the fairway (still feels good), and if I don't execute what I'm trying to do I have something to try and do better next time.


So, angles matter, even if the data says they don't matter for low scoring. 


I think we all agree golf wouldn't be all that enjoyable with straight, flat, hazardless, featureless courses (although people spend a lot of time at ranges so maybe I'm way off).

Two reasons.

1. The width vs. depth is not nearly as severe as you think. It's a pretty circular oval, often tilted a little back left to short right for a righty.
2. Again, as Kyle and I have been saying, trying to PLAY to those angles introduces more danger on the first shot. Who cares if you have a better "angle" that "fits" your shot pattern a tiny bit more if 2 of 7 drives end up dead in a fairway bunker you could otherwise avoid?

No to wind, yes to terrain because I've always said that they matter when the ball is rolling.

In other words, my Tobacco Road example, or "artistry" or interest or whatever. I've cited these other reasons many times, and they're all valid, but as you noted, I'm talking about scoring.

So, yes.

And I sometimes play shots that aren't probably the "best" in that situation, but just because I feel like it in the moment. I enjoy hitting good shots, but my definition of "good" is fluid, because sometimes I am taking the smart statistical play, and sometimes I'm goofing around a little, or trying something.

Mark - from the statistics I have seen, they literally do not matter for average score on most holes.  I am sure there could be exceptions but in those cases, the difference is so completely outweighed by the cost of a mistake as to obliterate any reason to chase a favorable angle. 

One of the Decade guys did an analysis of the 2nd Hole at Talking Stick North, which is a hole lauded for its strategic merit (see Ran's description here https://golfclubatlas.com/countries/talkingstick/?portfolioCats=249%2C250%2C251%2C252%2C253%2C254%2C255%2C256%2C257%2C258%2C259%2C260%2C261%2C262%2C263%2C264%2C265%2C266%2C267%2C268%2C269%2C270%2C271%2C272%2C273%2C274%2C275%2C276 )

He showed quite effectively that there is no upside in taking any risk in hitting it out of bounds left.  You are much better served giving the left side of the fairway a wider birth and dealing with the angles.  There may have been a slight advantage to the angle on the left side but it was very small compared to the penalty.

The interesting question to me is whether this insight should change our perception of the quality of the hole.  My gut says no but I am not sure why.   If one is rewarded for randomly pulling a tee shot that seem less worthy of esteem than having someone make a decision to take a risk and being rewarded.

Nothing in what you quoted says angles matter. Only what you aim at (i.e. not aiming near a bad bunker because the angle it gives you into the green is great).

You can play to the right spots and still occasionally pull or push a shot to the hole.

It’s just in the head is my guess. You can play away from OB from either side of the tee.


Actually, a good architectural comparison is a long debate about where to position the tee when OB (for example a road) is all the way down the left or right side. Some architects believe that placing the tee as far away as possible from the boundary line is the best answer, some believe that placing it on the boundary line and aiming the tee shot away from OB is the right answer. (This assuming the same tee-shot turning point in both cases). Data collected has never proven whether one or the other keeps more balls from entering the road.

That's just avoiding trouble, period, regardless of the "angle" with which you're left.
You did and I suspect you actually know that you did.


"The angle it gives you into the green is great" cannot, however you construe it, not mean that the angle into the green matters.  There is simply no possible way of interpreting that sentence that means angles don't matter.  What you mean, and what I said before, is that the benefit of that great angle into the green, is so significantly outweighed by the statistical disadvantage of playing for that great angle that it makes no sense to play for that great angle.


Jason's first sentence very concisely summarises your argument, and I am happy to accept that the statistics overwhelmingly prove that.  I'm disappointed, the strategic romantic in me wants to believe differently but I'm very willing to believe it.  But that summary and the statement that "angles don't matter" are not the same.  It might well be accurate to say that angles are far less important than we think, and that avoiding hazards is so much more important to scoring that angles should be ignored for scoring purposes, but that's, again, not the same as "angles don't matter".

You did and I suspect you actually know that you did.
Perhaps if I had put words like "angle" and "great" in quotes you'd read it the way I "said" it in my mind when I wrote it. I don't see situations where angles matter except:
Exceptions exist. I generally talk in generalities. Finding one situation (and the original bit that I replied to was a hypothetical) where an angle might matter doesn't "disprove" the general statement because I have not said "angles always matter and there are no exceptions, even when the ball isn't rolling."

But that summary and the statement that "angles don't matter" are not the same.
Do you want a disclaimer attached to every post about how there are some rare exceptions, or can we assume that the fine folks with whom we're talking here are smart enough to assume that people are generally not stating that things are 100% true 100% of the time with no exceptions?

Angles don't matter unless the ball is rolling*.

It’s a general hypothesis. Angles don’t matter because there’s not conclusive data that show they do matter.

This.

And from a coaching/teaching/caddying perspective suppose a player misses it to the so-called "wrong angle."

Do you want that player feeling like they missed and now have a bad choice in front of them? No chance?


Or do you want that player to know that the stats and data show they really are not at a disadvantage?

Which mindset is better for success? I know which one I'm choosing.

The fact that Lou put an eye catching newspaper headline on the article doesn't detract from its content.


Another way to look at it is that good golfers have learned (and now measured more precisely) that playing conservatively over a long season results in better scores.  I compare it to football coaches who become more averse to gadget plays as they progress in their career.  Sure, a Super Bowl winning play is exciting, but for every one of those there are 25+ plays that fail, and they know it.

According to Fawcette, widening fairways makes playing for an edge to get the open front angle is even more lunacy.  The biggest statistical difference in scoring comes from being in the fw vs being in light rough with spinners, but I think most of us intuitively knew that, so most should play tee shots to hit the fw in whatever fashion we can.


Another more depressing way to look at it is that all of us have devoted our time over the years to a website pushing a myth.  Ouch, that hurts!


Either way, the stats guys seem to be taking over the strategic thinking of the top young players.  I am not sure how architecture should adapt, but have been thinking about it.  Worth a thread maybe.

Not to belabor the point but when something is "not entirely clear", I would think its self-evident that all encompassing statements like "Angles don't matter" border on the absurd.

P.S. I don't think the varying sides are that far apart at this point.  I think nearly everyone would agree that on many or even most holes, they probably don't matter, but overall just looking for a bit more conciseness.  ;)

You guys are getting completely caught up in language rather than meaning.


The general consensus of those that follow GCA is that angles matter a great deal. Hence the title “angles don’t matter” is a way of showing that this is not entirely true. It is - of course - not an absolute. It wouldn’t work the other way round because the general consensus isn’t that way round. In that case, the headline would read “Angles actually do matter”.


That aside, I think that GCA connoisseurs don’t want to give up on this point because it’s one tangible aspect that can be easily understood and talked about. No-one wants to concede that “strategy” isn’t really the most important priority in an architect’s toolbox.

Only to those that think strategy is more important than it is and hence are deceived. That’s a pretty small sub-set:


Golfers who know how to score generally disregard it (or at least the angles part of it). The vast majority of other golfers (save for those who are into architecture) don’t even consider the strategy of a golf course as part of their vocabulary.

Ally,

I have a much harder time believing this last statement that strategy doesn't matter.

The best golfers in the world, (who are also the best scorers) talk a lot about how they develop a strategy before majors and other big tournaments.  They do site visits on their own dime, spend hours putting together a hole by hole game plan, practice shots they will need to win, etc.  And they talk about things like coming in from the right side of the fairway on 11 at Augusta or how the pin location on 2 leads them to decisions back on the tee.

Is all this just sound byte bullocks?

I’m not sure, Kalen. Hopefully Erik will chime in because he’s much closer to how the pro’s think than I am.


As I said, it isn’t an absolute. I always knew that angles mattered less than people thought but was not aware that scoring from the “wrong” side of the fairway might be as good as from the “right” side of the fairway. At my home course (where I have firmly believed that there is a right and wrong side), I still play away from trouble first and foremost. Being on the fairway outweighs playing from the “right” angle…. But I figure that most courses don’t really have a right and wrong side that are actually meaningful.

Erik acknowledged two important exceptions: when the ball is rolling and off the tee on doglegs. I mentioned centerline bunkers. Don’t they requiring playing the correct angle? I think Kyle mentioned SS Blue 8 (one great golf hole) as an example of another exception. But are centerline bunkers a general exception? You need to pick one side or another or take the risk of flying them.

I very much appreciate this sentiment.  The statistics are what they are, and they are important.  However, your intent to include this aspect of design is still welcome from my point of view.  There are things other than scoring when considering a golf course.  I do think visuals matter and angles affect visuals, so please carry on as you were.

Angles rarely matter. Angles almost never matter. Angles don't matter except in a few situations… whatever. It's all the same thing, and no different than what I've been saying. This isn't my topic: I didn't choose the title.

(Incidentally it’s not even Erik’s thread or choice of words).
Correct, thank you.

It's clearly just a hypothesis, but being asserted as immutable fact.
"Angles matter" is no less a hypothesis, except that the available data supports "rarely matter" far more than "often matter."

Another more depressing way to look at it is that all of us have devoted our time over the years to a website pushing a myth.  Ouch, that hurts!
Indeed.  :)  But again, the context in which they rarely matter is scoring.

There are some old-school people out there who haven't quite adapted, and a lot of the site visits are to find start lines (i.e. can I carry the bunker on this line, how much will the fairway slant kick a ball to the left, etc.), to figure out where you can miss it around greens, that sort of thing. A lot of their "strategy" is determined from an overhead view, like Google Earth or something similar, before they're ever on-site.

As I said, it isn’t an absolute. I always knew that angles mattered less than people thought but was not aware that scoring from the “wrong” side of the fairway might be as good as from the “right” side of the fairway. At my home course (where I have firmly believed that there is a right and wrong side), I still play away from trouble first and foremost.

Just about bang on.

Erik acknowledged two important exceptions: when the ball is rolling and off the tee on doglegs.
They can be if the dogleg happens in such a way that you almost have to shape the ball to hold the fairway. That's more about the angle of your ball flight, and the curve on it, than what we're traditionally talking about here with "angles."

Don’t they requiring playing the correct angle?
Uhhhh… quite often, no. If they're penal enough, you're often treating it like it's on the side of the wider part of the fairway. Or if it's penal enough, you're hitting a 3W to stay just short of it. The fairway bunker on that hole at Kapalua or whatever is interesting… because it's next to a cliff or whatever, and there is an incentive to get it to the green in two.

And I've also said that I'm talking only about scoring. If angles matter to you for artistry/beauty, or for "interest," or any other reasons, cool. They "matter" for those contexts. I've talked only about scoring.

Trust this might have been stated already as I have not read all six pages of posts:

Obviously course conditions are paramount but ALL golfers, outside of maybe the highest handicappers and pure beginners, realize that angles can matter.  That said, the better the player the more important they are because they can do something about it.  When your primary focus is to make solid contact and finish the hole with the same ball, you are not really worried too much about angles.   


Same as saying don’t be above the hole on really fast sloping greens or leave your approach shot short sided behind a bunker.  Higher handicappers surely understand this but their ability limits what they can do about it.  The better the golfer the more they can control their outcome. 


Also play a course with aerial hazards like Harbour Town or Valderrama and then decide if angles really matter. 

One more clue to determine if angles really matter to a particular golfer - watch what they do on the tee.  If they tee up their ball on one side or the other rather than right in the middle, you will have your answer.

My son, a good golfer, has an interesting take on this.  Basically, when he comes in from the "wrong" side of the fw he does play for the fat part of the green, thus basically incorporating the Decade Strategy of playing safe, and probably his overall score goes down as a result.  When he has the better angle to the flag, he attacks and gets in trouble more often, raising his average score, and it all averages out.


I guess the term "sucker pin" is rooted in reality somehow.

Nobody here really knows how to improve, do they?


One of the premises here is that angles don't matter because the amount of time to acquire the skill such that you're overcoming the variance in your golf swing to have such command over the ball to take advantage of every angle that may give you an advantage (assuming you're aware of it in the first place) is legion.


Take Iron Byron out there and angles matter.

You are not Iron Byron.


In almost every case where the angle matters there is sufficient width within and distance between the two options that you're making the choice between being within reach of the green in regulation and not. Yes, your ability to hit the ball far enough matters here but that's if, and only if, you can subsequently take advantage without putting the penalty shot in play.

Put another way: Old Man Par never chases angles.

That's interesting comment from your son but it seems to assume a binary choice of going for the pin or playing completely safe. From the correct angle he can choose to play somewhere in between. His chances of success of sinking a 15 ft putt are surely better than sinking a 30 ft putt ?


Maybe by playing in between he would slightly increase his chances of going in the hazard but then there might be a fair chance of getting up and down if he's a good player and let's also not forget that there is a much better chance of 3 putting from 30 ft than from 15 ft. There is such a thing as playing too safe.

Your son is wise, Jeff. One summer I was entered to play in the Michigan Mid-Am. Per usual, I was trying to cram a year's worth of practice into 2 weeks. The pro a the club where I was a member, Lochenheath, asked if I wanted to play a quick 18 holes that evening. We'd be the last 2 players on the course and could probably zip around (in a cart) in 1.5 - 2 hours. Sounded good to me so at around 7 pm we took off to the 1st tee, teed off and chased after our drives. As I got out to the cart, I was surprised to find there was no pin/flag on the 1st green and asked our pro what we should do. He said, "Well, we're out here, let's get some practice in and just hit to the center of the greens."


I was actually surprised at the end of the round that my score was not much worse. In fact, it was right around par. It was then that he told me he had the greens crew remove all of the flags before our round and that unless I had a wedge in my hands, it'd be wise to hit to the center of the greens during the tournament.


Somehow, during the 1st round of the tournament, I was -3 thru 5 holes and that was enough to convince me that I was in the zone and started taking "Dead Aim" at all flags.


Suffice to say, I flamed out on the front 9, but that didn't stop me from "Flag Hunting." I shot a million but eventually learned the lesson.

It's not really Jeff's son's take: that's what Lou has said all along as well: people play more conservatively when they have the "wrong" angle, which is actually roughly where they SHOULD play from any angle, but they'll typically aim closer from the "right" angle and short-side themselves or whatnot.

I'm surprised that nobody has tried to show that "angles matter" by looking at the stats and showing something like this… Let's say that from 150 yards in the fairway a class of player averages 3.12 shots from the "bad" angle and 3.15 shots from the "good" angle (so, a pretty good player). Those are so close it's basically a wash, but how they get those averages might be something like this, out of 1000 times played:

"Bad" Angle (4.12): 1 eagle, 111 birdies, 667 pars, 218 bogeys, and 3 doubles.
"Good" Angle (4.15): 3 eagles, 129 birdies, 592 pars, 265 bogeys, and 11 doubles.

That might show "angles matter" a little… because the scoring spread changes. One location results in more under-par scores but also more over-par scores with fewer pars. But then I'd counter to point out that these stats are derived only from shots hit from the fairway,  so if the "better" side of the fairway also has a fairway bunker over there, then that is going to massively affect the scoring, and that you shouldn't play for that angle you should play for safety first… and so on. Which is what Kyle and I have been talking about, ultimately.

That's why the ultimate target is often still basically the same on the green (or should be) regardless of where you're playing from… (as long as the ball isn't rolling, and any other rare exceptions).

But you would have at least shown that even though the numbers can work out the same, the actual resulting angle might matter in that sense. It'd be looking at it a little too closely, and not seeing the bigger picture, but it'd still speak to the point a bit.

Angles matter to a golfers ego.  This method is just trying to say, stop trying to satisfy your ego and hit it in the fairway and away from hazards.  It’s basically saying even if you can make an eagle from that perfect angle 10 yards wide surrounded by trouble during Friday skins, don’t go for it.  Now, even if you have a 10% chance of hitting that spot are you going to go for it? If the answer is yes, it’s because of your ego.  It might not help your average score in your medalist match against yourself for the rest of your life, but if you pull that off and then the next two subsequent shots and come away with eagle, you will be richer than when you started the day. Your ego is willing to accept that trade-off. If you fail, and pick up your putt for 6 your ego is damaged, but your score is not really affected, because we are just playing skins. If you played without your ego, maybe you could have made a 3 or 4 too, but you could also make a 5 or 6.  It doesn’t guarantee you a better score in every situation, it just increases the probability and minimizes the risk to get there, over time.


Angle mitigation=risk mitigation.  That is all this statement is saying.  Before you make any of these decisions you are choosing between 50 degrees of angled instruments to counteract the angle on the ground.  Most of them have nicknames like 7 iron, why?  So you don’t have to think about all of those angles.


Angles were introduced on purpose to mess with your ego.  The Golden Age architects wrote about risk and reward to your ego, they didn’t always say one angle was better than the other for your score.  To make a truly strategic hole, you should be able to play successfully on more than one route.  If you give golfers decisions, their ego is usually going to get in the way.  Angles create decisions.  If you can make angles seem like they don’t matter then you have eliminated a major outside influence to your game. It’s all sports psychology, and in many instances, it’s easier said than done.


The catchphrase was well thought out, because if your ego thinks angles matter, you will chase this title.

Statistically, the difference in 15 and 30 foot putts is 0.2 strokes, from expected putts of 1.68 to 1.98. 


I'm not sure the choice is purely binary, as in lay up short.  Every stroke has a bit of nuance in it, as in aiming for the fat of the green, but adjusting grip or stance to get it to curve towards the pin a bit.

That's the point I'm making, it is rarely totally binary. There is usually a sliding scale of how much risk a player will take on with a shot which will depend on their skill level, how well they are playing on the day etc.


Bret


I've read a lot of the ODG's on strategy and can't recall them discussing ego, however they certainly allowed for different levels of golfers getting to the green in different ways. MacKenzie's Lido hole being a case in point. I might add that their designs also had the players playing off the same tees.

It's not really Jeff's son's take: that's what Lou has said all along as well: people play more conservatively when they have the "wrong" angle, which is actually roughly where they SHOULD play from any angle, but they'll typically aim closer from the "right" angle and short-side themselves or whatnot.

I'm surprised that nobody has tried to show that "angles matter" by looking at the stats and showing something like this… Let's say that from 150 yards in the fairway a class of player averages 3.12 shots from the "bad" angle and 3.15 shots from the "good" angle (so, a pretty good player). Those are so close it's basically a wash, but how they get those averages might be something like this, out of 1000 times played:

"Bad" Angle (4.12): 1 eagle, 111 birdies, 667 pars, 218 bogeys, and 3 doubles.
"Good" Angle (4.15): 3 eagles, 129 birdies, 592 pars, 265 bogeys, and 11 doubles.

That might show "angles matter" a little… because the scoring spread changes. One location results in more under-par scores but also more over-par scores with fewer pars. But then I'd counter to point out that these stats are derived only from shots hit from the fairway,  so if the "better" side of the fairway also has a fairway bunker over there, then that is going to massively affect the scoring, and that you shouldn't play for that angle you should play for safety first… and so on. Which is what Kyle and I have been talking about, ultimately.

That's why the ultimate target is often still basically the same on the green (or should be) regardless of where you're playing from… (as long as the ball isn't rolling, and any other rare exceptions).

But you would have at least shown that even though the numbers can work out the same, the actual resulting angle might matter in that sense. It'd be looking at it a little too closely, and not seeing the bigger picture, but it'd still speak to the point a bit.

The bit in your post that jumps out at me is "as long as the ball isn't rolling, and any other rare exceptions". That basically is the nub of the discussion. For instance, equally you could have argued that angles do matter except where the design and conditioning of the course negate the benefit of approaching from the "right" angle. It's pretty well the same conclusion but just coming at it from the other way.

I guess I find it quite depressing that the ball rolling is considered a rare exception.  Golf is so much more fun when the ball rolls.  Is that (at least in part) because it makes angles matter?

That's the point I'm making, it is rarely totally binary. There is usually a sliding scale of how much risk a player will take on with a shot which will depend on their skill level, how well they are playing on the day etc.


Bret


I've read a lot of the ODG's on strategy and can't recall them discussing ego, however they certainly allowed for different levels of golfers getting to the green in different ways. MacKenzie's Lido hole being a case in point. I might add that their designs also had the players playing off the same tees.


Niall


Niall, I think when they say “bite off as much as you can chew” they are talking about your ego.  No golf architect ever said that if you take the preferred line you will automatically win the hole. They just mentioned an advantage.  The advantage is perceived by your mind.  You still have three or four more shots before the final score is determined. Macdonald makes it clear in his book that golf courses shouldn’t be laid out for scoring competitions. Macdonald wanted to bring out golfers intuition, he wanted them to make decisions because he knew every decision was a chance at disaster or greatness.  Luck and ego are very difficult to measure with statistics, but they are still an important part of the game.


In my own experience I can think of times where I forego a better angle for a clearer look at the green.  On Yales 8th hole, I prefer to be way off to the right so I can see a sliver of the green.  The angle is not as good as it is from the left, but I can’t see the green from the left.  My ego tells me I want to see the green so I try to satisfy that.  The angle doesn’t matter to me in this situation as much as the clear look.  Other golfers may prefer the better angle with no look. College kids can hit over the hill and have a look from either side. That is an angle my game is unfamiliar with. In either case I score about the same from both places.  Neither one is such a penalty that I can’t still make a 4 or 5. However, even if I score well hitting from the “wrong” side all day I feel mentally worn out by the end of the day because my ego was rarely satisfied.

This has been a major aspect of my point. I don't play many soft, flat, windless golf courses. I have been playing Cleeve Hill a ton this winter. Wrong angles can easily be a matter of 1 or 2 extra shots rather than .1. It's a huge difference to playing my home course which I agree, it's get the ball on short stuff time. Worry about the next shot later. The course simply isn't wide enough to consider many angles.

Correct Niall. Strategy is - in the traditional golf design use - a bit of a myth. I said as much back on page 1 of this thread.


But it is one element of design that everyone with an interest understands. So we hang on to it with all our might.


That’s not to say that it is impossible or that you can’t add choices or enjoyment in to golf holes through angles. Of course you can. And thus, I will keep striving to add various forms of strategy. And probably also proliferate the myth.

It's the exception around the world. And unlike the "rolling a few inches" thing from earlier in the discussion, I'm talking about a reasonable amount of roll, not "hit a 7I that rolls out ten feet." I'm talking about "land your 7I eight yards short of the green so it bounces up and rolls on."

I am hardly going to provide a map and shot location for the past four months that will be mis-analyzed by a guy on the other side of the ocean that doesn't know the course or my game. A synopsis will have to do.  😎 It's fine that you don't trust or believe me. But I trust my experience far more than I do anonymous blobs on a graph. I do get it wrong sometimes and that's ok. In truth, the shorter my carry has become the more I rely on angles and the more I avoid courses and conditions which don't provide for angles.

It doesn't seem to occur to you that maybe your rare incidences of angles mattering is not so rare for a lot of golfers. But hey, I can tell myself angles don't matter after watching my ball roll 30 yards down from a green because I came up short trying to play over a ground feature. No, the blobs on the graph tell me that shot wouldn't have been far easier to execute from a better angle. No, seeing stuff like this happen hole after hole from our 4 ball is just a rare statistical blip. It's helpful to tell each other that for 4 hours as we record 25 points then do the same next week. 😕

Sean,


It would be interesting if you did track a hole where you think angles matter, as in play it ten times, with tee shot finding right and wrong side of fw, including shots that find hazards.  Then track your score.  Despite the title, the theory is that over 10 plays you would probably make 1 birdie from the favored side, but two bogeys from hitting a hazard on the right side.  Thus the aggregate is likely to be about equal over time, but not on any one shot.


The difference between 95 and 70 for players who average 75-80 is 18% attributable to birdies and 82% attributed to bogey avoidance. It is probably higher as handicaps raise.  In essence, birdies are rarer than bogeys for all players.  If you make bogey, you need two birdies to advance on par, similar to losing and then gaining 10% in the stock market......90% of $100,000 is $90,000, and 110% of 90,000 is $99,000, a slight loss.  I think that is what these stats say.  Good scoring is about bogey avoidance, first and foremost, however you get there.


As to ego that someone mentioned, I do think Mac said something to the effect that the player must know his own limitations and then execute.  That is sort of saying to tame your ego when playing, which is what these stats say, as well.  That we are in the information age and you can pre-measure carry distance in many ways, there is really little excuse for the average guy to try a carry of 220 yards when he knows he can only carry 215 with his best shot, probably closer to 200-205 on an average day.  And, I think these stats show that.  (I picked numbers that both you and I probably relate to. ;D


Again, just because over time "the house wins" it doesn't mean that any individual decision you make to take on risk is necessarily wrong or that it won't work out.  It's just that it typically doesn't. :)

Post by: Sven Nilsen on February 22, 2023, 11:51:26 AM
I think the gist of what is being said is that sometimes angles can matter.  In my experience, it's a fairly significant "sometimes."


Some days you might feel it, and any risk is probably more worth it.  Somedays you know you don't have it, and you might want to play a bit more conservatively.


On some courses, the roll from a fast and firm surface might make lines off the tee (and club choice) extremely important, while on a nice soft course after a day of rain, hitting to the middle of the safe area is all you need to think about.


In a match where you're down going into 18, perhaps playing for a better angle is the best move.  And maybe in the opposite situation, you might want to just keep a ball safe after watching your opponent dump one into a hazard.


Golf is unpredictable, subjective, situational and never the same one day to the next.  Throwing out absolutes, or trying to use data taken from the collective to create rules for the individual isn't always going to work out.


Know yourself, and play within that game, and you'll score better.  Real golf IQ derives from understanding one's capabilities in a variety of conditions, and when it makes sense to stretch their limits.

This would take some time to include wind direction and seasons. It would also likely mean going to exact spots and hitting several balls from perceived angle differences.  That is not something I am going to do.  8)  I have a good understanding of my limitations and am generally risk adverse if I am playing for something...which is rare. Usually the most I am playing for is my ball. I hate looking for it.

The “I know it cause I know it” crowd sure seems to be struggling with the golf analytic crowd. Interestingly, this same thing happened in baseball, then basketball, and now football. Moneyball seems so old hat now, makes me wonder how all these people giving “data” to Erik (and Scott and Lou) will feel in a decade.


To be fair, I patently disagree with the Lou’s statement that I quoted to start this thread. Not because angles DO matter to scoring. No, more than not it’s been shown that it really doesn’t matter in regard to scoring. The reasons I dislike the quote is because I want architects to continue designing and using angles. I want golf to be a weird combination of challenge, fun, athletic, and cerebral. Strategic golf design is at the heart of that.


I’d implore the combatants here to go back and read Tom’s reply #67 in this thread.

Post by: Jeff_Brauer on February 22, 2023, 12:56:16 PM
To be fair, avoiding hazards at all costs is a strategy, too. (See Tiger Woods and British Open)  As is bailing out, hitting to the fat part of the green, adding 2 clubs for wind instead of 1, playing up on a new set of tees, hitting it where you see it (or as you age, hitting it where you might remember it), etc.


And, in reality, I think most golfers see hazards out there as stop signs, not "hit it here challenges."  The challenge of the tee shot can be the shot itself, fitting it in a slot, using a turbo boost, finding a flat lie, laying up short of hazards, curving the ball to stay in play (statistically, again) and any number of things you might concoct.


So, if all a fw hazard does is challenge you to stay out of it, that is okay, too.  As I said before, taking the shortcut route at some risk really only works great on par 5 holes of a certain length, because you actually can gain a full stroke.  Taking a risk to save an average of 0.2 strokes on a par 4 is probably nearly always bad math. :D

Post by: Ally Mcintosh on February 22, 2023, 01:34:23 PM
There are loads of different strategies and uses of angles in golf and golf design. What the figures - and my experience - is really arguing against is the amount of influence the “strategic school of design” has on a round.


The strategic school is only about risk / reward chasing of angles.


In many ways, the heroic school is a much more influential school because it is actually about using an angle to reduce distance for the next shot rather than just to produce a better angle…. And there’s no denying that shorter approaches are better for scoring than longer approaches.


Ironic that the heroic school was a post-golden age product whilst the strategic school was the main calling card of the golden age.

I would bet that a greater percentage of players see hazards as a yellow caution rather than a red stop sign. If you take the card and pencil devotees out of the equation and apply human nature and emotion which in my experience have an outsized effect on the game many/most are willing to take on the risk regardless of what the statistics bear out. In match play which is the preferred game across the land medal score doesn’t mean much at the end if you shot the lowest score but are on the team that’s reaching into their wallet. I won’t argue that to make the statistically “smart” play will more often than not produce the best medal score but that’s not what delivers the most enjoyment for me day in and day out.

I agree that everything you said forms part of the enjoyment. I’m not sure anyone disagrees with that… I think the general gist of the thread is that people get really enthused about classic strategy when in reality it has (or should have for the discerning golfer who plays to win) a comparatively small role to play.


It definitely has a role though. I would hate to see strategic design reduce. Just don’t hang your hat on it.

It doesn't happen as often as you think it does. Even a ball rolling 5' past the hole has to hit almost the exact middle of the hole to go in. But that's OT for this topic.

We know, you've said it before, ad naseum.


What you aren't acknowledging is that there are way more golfers out there than the guys on tour.  Stats might help .001% of the people who play the game, but they're not going to help the majority of golfers.  In the greater scheme of things, it's negligible, a concept you've enjoyed throwing around in this thread.


Golf IQ, for the majority of players, isn't derived from stats.  It's derived from experience.  The smartest players know the limits of their abilities, not from stats, but from self awareness.  They know when a little more club is better than a little less, when playing down the middle makes more sense than playing close to trouble, etc.  And there are a ton of factors that go into each and every one of those calculations.  I know, because I help people make these calculations on the course on a daily basis.


I understand where you are coming from.  You are selling an ideal, one that people see every week on TV.  Unfortunately, most people's problem is that they don't realize that they'll never measure up to that ideal, that of the "better player," and that if they want to shoot lower scores they should play smarter.

Sven,


I am 100% a “feel” player. I play all my golf at links courses, my home course is one of the firmest, fastest and strategic courses there is. I have low launch and use the ground a lot. I don’t check distances (another topic - I should of course). I love angles, I try and design for them wherever possible.


And I agree with Erik: Generally speaking, we  place too much emphasis on traditional “strategy” (there are all types of other strategy). All types of golfers tend to score better by playing safely than by risking the hazards that come with chasing angles from the tee. This is because finding the hazards loses more shots than the shots gained from occasionally playing from the “right” side of the fairway. And that is partly because there isn’t as big an advantage gap between the “right” and “wrong” sides of the fairway as our imagination would like us to believe. Not to mention that most people can’t hit the “right” or “wrong” side even if they try.


This isn’t just for tour players.

Sven-Erik has been trying to hawk his “system” since he appeared on the scene here at GCA. Sometimes it’s overt while other times more nuanced depending on the topic. I’ve never gotten the sense that he has any sort of admiration for architecture or the golf courses themselves but rather sees his sign on as another business opportunity.

Post by: Ira Fishman on February 24, 2023, 09:36:55 AM
Ally,


I completely accept that the penalty for chasing an angle unsuccessfully is greater statistically than the reward for being successful. But Sven and others have made the point that there are lots of ways angles come into play strategically. Take for example number 9 at Pine Needles. The fairway is wide, and there is no hazard that needs to be played away from. But if you are coming in from the right, it is a significantly more difficult shot than from the left. My memory is fuzzy but I think the same is true at Royal Dornoch 5 given the angle (that word again) of the green.


Sven can probably give some examples at Bandon where playing a tee shot that looks to be at a safe angle away from a bunker actually is not a smart play. I found out the hard way several times when I did not execute on his advice.

Ally,


I understand that point.  The nuance you are missing is that the "right side of the fairway" can be different for different players.  The best path for every golfer is not always the same path.


How can you apply a very generalized statistical analysis to what is going to work for each individual golfer, on any given day, under one of a myriad of different conditions.


My main issue here is that you and others are simplifying the concept of strategy to that of an ideal.  Your concept works under that premise.  But there's way more to strategy than two connecting straight lines on a par 4.


Sven

If you know, why do you continue to say stupid things like "No stat geek from the institute of confusing bull crap is going to make you a better player."?

What you aren't acknowledging is that there are way more golfers out there than the guys on tour.
When did you fall in love with making such wildly inaccurate statements? Where have I failed to acknowledge this simple fact?

Stats might help .001% of the people who play the game, but they're not going to help the majority of golfers.
Incorrect.

If you can't break 120, you probably aren't going to get much out of strategies based on statistics. But if you can plot a reasonable Shot Zone, you can apply what I teach to play better golf.

Golf IQ, for the majority of players, isn't derived from stats. It's derived from experience.
That doesn't mean it has to be. Scott named his system DECADE in part because it forms a goofy acronym, but also in part because he says it shaves a decade off learning these types of things.

You can say "green reading is an experience," or you can take an AimPoint class and greatly accelerate that learning.

The smartest players know the limits of their abilities, not from stats, but from self awareness.
And yet… PGA Tour players are hiring statistical consultants.

They know when a little more club is better than a little less, when playing down the middle makes more sense than playing close to trouble, etc. And there are a ton of factors that go into each and every one of those calculations.  I know, because I help people make these calculations on the course on a daily basis.
What do you think statistical analysis and Shot Zones and what I call "Decision Maps" and stuff are?

I understand where you are coming from.  You are selling an ideal, one that people see every week on TV.
No.

Unfortunately, most people's problem is that they don't realize that they'll never measure up to that ideal, that of the "better player," and that if they want to shoot lower scores they should play smarter.
Ummmmm…

I've never said it is.

We don't do that. Everyone's Decision Map is different.

If that misunderstanding lead to what you wrote a bit earlier, that makes a little more sense to me how you could be so far off base. In talking online, you have to talk pretty generally. When talking about a specific golfer, you can be more specific. Most of the conversation here is very generalized. Kyle's done it, too. It's the only real way to talk about things, unless everyone is going to talk about and understand ONE specific thing.

Tim, your post is entirely bogus. And probably doesn't even deserve that much of a comment.
Title: Re: “Angles Don’t Matter”
Post by: Erik J. Barzeski on February 24, 2023, 10:54:59 AM
Take for example number 9 at Pine Needles.
Great. A specific example, and one we can talk about a bit more specifically (there are still going to be modifications based on player strengths, the tees they play, any "fears" or great weaknesses they have, etc.).

Here is the hole from the yardage book:
https://share.getcloudapp.com/kpuA1p0y (https://share.getcloudapp.com/kpuA1p0y)

Here it is from Google Earth with some measurements on it:
https://share.getcloudapp.com/jkuAgz5b (https://share.getcloudapp.com/jkuAgz5b)

A few statements were made:

The fairway is wide
Ah, but it is not, really. At about 245 or so, it's a little under 30 yards wide:

(https://p197.p4.n0.cdn.getcloudapp.com/items/d5uglL4n/e0640e4b-582e-4c20-8ab1-2a6d9728c468.jpg?v=f62908de9c0c50c0fb4e14a2c121c861)

That's significantly less wide than the average golfer's shot dispersion. In fact, shot dispersion is still about 60-80 yards for a wide range of players. As they get better, they hit it more "accurately" (by degrees from center), but also farther (2° offline at some distance will be just as far from center as 3° at a shorter distance).

The corridor, from the second image linked to above, is only about 55 yards. Let's be generous and call it 65 yards, and pretend that you don't mind playing off pine straw and sandy scrub areas too much.

Just establishing some measurements.

and there is no hazard that needs to be played away from.
There are no "hazards" but there are hazards. See below.

But if you are coming in from the right, it is a significantly more difficult shot than from the left.
Let's assume that Ira is correct and that playing from the left side of the fairway is easier than playing from the right. (I actually prefer to be right so I can hit away from the swale to the right of the green, not to the left hitting toward the fall-off, but let's go with the "left is best" approach here).

There are basically no golfers alive who should be aiming here if they want to score their best on that hole in the long term:

(https://p197.p4.n0.cdn.getcloudapp.com/items/P8u2vZ6k/dae14252-f755-4414-a3cf-11438d16d047.jpg?v=9700a61a7e7c9c09e7b36930fcd0c8ec)

Because, as I kinda said above… there is a hazard that needs to be played away from on this hole: the freaking TREES. They're on both sides of the fairway, and it's not worth it for almost anyone to play to a "side" of the fairway for the small fraction of a stroke an "easier" approach shot might save him by risking whole strokes hitting it into the trees more often.

The advice, the "strategy" here, is to aim down the middle of the alleyway (which may not be the exact middle of the fairway). When you find yourself to the "bad" right side, you say "awww, shucks, I rolled a 5 this time, but at least I'm in the fairway" and you try to hit the green. And when you find yourself to the left, maybe that's the time you say "ah, variance fell my way this time" and you feel good about having rolled a 6 on the dice that time. And then you try to hit the green.

This all ignores that whether a golfer is right or left in the fairway, they're probably going to score about the same. It may change how you feel about the approach shot, but… it probably won't affect scoring all that much. The fairway is not wide, nor is the corridor itself all that wide. You should not "pick a side" of the fairway to hit here. You should aim down the corridor and let your Shot Zone or pattern fall where it will.

Kyle's been saying the same things, too. Thank you, Ira, for the example. Specific examples that we can all look at and be on the same page allow us to talk in more specifics.

From the most recent posts, am I correct in saying that the stats are based on par 4's where for the position for the approach shot with the best angle to the green being guarded by some sort of hazard ie. bunker ? What of holes where not being in position is the penalty ? Maybe where a combination of line and length off the tee is required to find the best path to the green. Presumably they aren't in the stats or is the suggestion that in that instance also the angle of approach doesn't matter ?

We'll agree to disagree.  Most players would be better served focusing on pace as opposed to an aiming system for lines that they can't hit anyway.

Pace always matters more.  Unfortunately most players ignore it because they're too wrapped up in trying to figure out whether it's a 2 or 3 percent slope on a putt that breaks three times before it gets to the hole.

Also not touched upon, but I believe the type of match might influence this, i.e., in match play you only lose one hole no matter what, which limits the negative effects of finding a fw hazard or green hazard and increased the possibility that angles might help.


Just a thought.

Rich Hunt, who publishes the annual "Pro Golf Synopsis", would be an interesting person to have a take. 


I think the par 3 #6 at Tobacco Road would be a great case study in angles.  Strantz built tees about 75 yards apart so the hole can play to a long/skinny green or to a wide/shallow green depending on the daily set-up.  I thought the concept was pure genius...do any of the angles folks think the hole plays easier in a particular configuration?





Title: Re: “Angles Don’t Matter”
Post by: Ally Mcintosh on February 25, 2023, 03:01:21 AM
I’m going to have one more go here before I move on:


Those that are arguing for angles seem to think that the against lot aren’t being deep enough in their considerations. I tend to think we’ve gone deep and then further. Anyway, my position is talking only about classic strategic design 101 which is - in its simplest form - about rewarding a riskier drive with a more desirable angle in to the green. I concede all the nuances. I live them all the time on the golf course (actually one thing that hasn’t been mentioned is how we tend to execute a better shot when we feel comfortable visualising that shot’s outcome).


So, taking Strategic Design 101 on a par-4, there is a part A and a part B:


PART A: THE DRIVE.
As Eric has demonstrated quite well in Reply 193 to Ira, it - almost always - makes no sense to aim for one side of the fairway or another. Even on the most strategic courses, I will be aiming down the middle of the fairway (unless there’s a centreline bunker in which case I will choose one of the two split fairways to aim down the middle of / lay back from etc….). This I always knew, partly because skill levels aren’t high enough and partly because I suspected PART B to a certain extent.


PART B: THE APPROACH
Part of the reason it’s better to aim down the fairway is that apparently - and I didn’t know this - there isn’t much difference to scoring from the good side of the fairway than the bad side of the fairway. Now I haven’t studied the stats and personally, I still like coming in from a more “comfortable” angle. It makes me feel more confident. But I’ve known all along that there is a small enough difference in scoring that I don’t go chasing that comfortable angle because the risk outweighs the reward. If I aim it down the middle, I’m going to end up on the good side by chance quite often.


You don’t have to explain temptation, lines of charm, diagonal carries, wind, ground movement etc… etc… to me or I suspect the others. I know all that. This is about scoring. If you are just going out to hit golf shots and have fun, take it all on… but then, as I remember one argumentative thread many moons ago, is that golf or just practicing for golf?

No, hence words like “apparently”, “I didn’t know this” and “I haven’t studied the stats”. I would have thought that was obvious!


But I did - through common sense in knowing my own game - suspect the difference was small, hence my general application of Part A.


Rob, not sure what you’re asking with the curve of the drive? If I aim down the middle, sometimes I’ll end up on the “good” side, sometimes I’ll end up on the “bad” side, sometimes I’ll miss altogether. But crucially, I’ll miss less often than if I head down one side or another…. (This is talking about finishing point, discounting natural shot shapes which I’m sure we all account for to one degree or another when aiming).

Yes, I could have framed my question a bit better. I was really trying to find out what the data purports to show beyond the simple "Angles Don't Matter". For instance, is the suggestion that it doesn't matter whether you approach from an angle with the green open or with it well guarded, in that the scores will be more or less the same ? Your part B seems to suggest that's the case. Did you get that from Erik or from some other analysis of the data ?

I don't think anyone has established this. I was trying to do this a few pages back when I eyeballed the scores from the good/bad side of the layup zone on 10 at Riviera. It looks like the scoring is lower from the good angle side, but you can't actually calculate it in the link that Erik posted. I suspect that it isn't a huge difference, though. And that's just one case, one only involving the pros.

It may be pedantic in the real world where we should just be trying to avoid hazards off the tee, but I'd like to see how the scoring averages would differ if we put different skill level players on the good/bad side of the fairway (so controlling for hazards on the drive) at various distances when the angle should matter. Because if the good angle matters, maybe one of the things we should be doing is designing holes where we want the angle into the green to matter to have minimal hazards off the tee--the point that I was trying to make in my other thread.

But it's also possible that even in this best case scenario, the angle wouldn't really matter because players will be more likely to aim for safety when they have a bad angle and/or get too aggressive from the good angle. Hell, you might even get a counter-intuitive result--that scores are lower from the bad angle.

I'd like to know this and I think it'd be important, at least for golf course architecture enthusiasts, to know this. Maybe all of the interesting theory about using the angles of greens, hazard placement, and slopes to create 'good angles' just doesn't matter much. I--and we--might have to reassess some of what we think makes golf courses better and worse if we do the proper tests and get no result or a counter-intuitive one.

Brett,


The reason I brought up ego earlier in the thread was because it’s been mentioned in so many responses but not recognized as such.  When you  have a tendency to play more aggressively from a good angle or more conservatively from a poor angle that is because of your ego. The diagonal hazard always has been and will continue to be an effective tool for golf architects to use, because their job is to test a golfers perceived ability against their actual ability.  Perceived ability is your ego.  Even though you’ve cut the corner 10 out of 10 times this year doesn’t mean that angled hazard never matters.  If you miss a shot or if the wind freshens as you hit your tee shot, maybe that carry isn’t as attainable as it was last week.  Just because statistical averages say angles don’t matter doesn’t mean they can’t matter in real situations.  The “outliers” mentioned earlier are actually part of the data, they aren’t outliers to the data, they are just outliers to the statement “Angles Don’t Matter”. These “outliers” were part of the data used to come up with the average.


I keep reading the assumption that if players chase angles they do it on every tee shot on every hole.  I think this is a poor assumption, because I don’t play golf with anyone that cuts every corner and chases every angle.  Golfers generally pick their spots.  They may find one corner to cut in the round that gives them a real distance advantage. Maybe they feel lucky? Maybe their personal statistics are better than the National Average that day.  For whatever reason they only want to cut one corner, they aren’t taking on everything on every hole. If they are cutting corners all day unsuccessfully,  I think even intuitive golfers would recommend they work on their course management.


The question we should be asking ourselves, is how much do probability statistics matter to our game?  A good example not involving angles would be when you are invited to a fancy country club and are given a caddy you have never met before. You come up short on your approach and you grab the wedge visualizing the shot you want to hit, but then the caddy stops you and hands you the putter.  He is offering you the statistically better play regardless of the shot you just visualized.  Do you take the putter (even if you never practice that shot) or do you go with the shot you visualized? If you do go with the putter against your will, do you feel satisfied after the shot? If the answer is no, then statistics probably don’t matter either!

PART B: THE APPROACH
Part of the reason it’s better to aim down the fairway is that apparently - and I didn’t know this - there isn’t much difference to scoring from the good side of the fairway than the bad side of the fairway. Now I haven’t studied the stats and personally, I still like coming in from a more “comfortable” angle. It makes me feel more confident. But I’ve known all along that there is a small enough difference in scoring that I don’t go chasing that comfortable angle because the risk outweighs the reward. If I aim it down the middle, I’m going to end up on the good side by chance quite often.



Ally


Do you know for a fact that is what the survey/data says ? I asked the question in another post and don't think I received a reply.


Niall


No, hence words like “apparently”, “I didn’t know this” and “I haven’t studied the stats”. I would have thought that was obvious!


But I did - through common sense in knowing my own game - suspect the difference was small, hence my general application of Part A.


Rob, not sure what you’re asking with the curve of the drive? If I aim down the middle, sometimes I’ll end up on the “good” side, sometimes I’ll end up on the “bad” side, sometimes I’ll miss altogether. But crucially, I’ll miss less often than if I head down one side or another…. (This is talking about finishing point, discounting natural shot shapes which I’m sure we all account for to one degree or another when aiming).


What I'm getting at is that I play a draw. If I aim down the middle I'm going to spend a lot of time in the left rough or worse. I use angles on the tee box and start line to get my ball in the fairway.

So, Should You Play For The Better Angle?
[/t][/t][/t][/t][/t][/t]
For as long as the game has been played, people have been saying you should play for the better angle. The hole is cut on the right? You should try to hit it up the left-side. The advice is as old as the game itself.

Is the advice accurate? Is it easier to score when you have the "better angle"?

To answer this question I took a deep-dive into the Arccos (https://golfstatpro.us21.list-manage.com/track/click?u=f14910584d0a34c8ff08be313&id=72bba4f48d&e=a1395c42f5) database. There are 581 million shots in the database, so there isn't a question Arccos can't answer.

[size=inherit][/t][/size]
[size=inherit][/size]What Shots Were Selected?
[size=inherit][/color][/t][/size]
[size=inherit][/color][/size][size=inherit][/color]For a shot to be used, it had to meet the following criteria:[/size]
  • [size=inherit][/color]Second shot on a par 4[/size]
  • [size=inherit][/color]Fairway was at least 30-yards wide where the ball was[/size]
  • [size=inherit][/color]Hole was cut 6-yards or less from the right/left edge of the green[/size]
  • [size=inherit][/color]A shot on the "side" of a fairway needed to be close to the edge (20% or less of the fairway width)[/size]
    • [size=inherit][/color]For example, on 30-yard wide fairway, the ball needed to be 6-yards or less from the side-edge of the fairway[/size]
  • [size=inherit][/color]A shot in the center needed to be in the middle 25% of the fairway[/size]
    • [size=inherit][/color]For example, on 30-yard wide fairway, the ball needed to be 3.75-yards or less from the center of the fairway[/size]
  • [size=inherit][/color]No penalty hazards in-play around the green [/size]
  • [size=inherit][/color]Shots from the rough were not recovery shots[/size]
  • [size=inherit][/color]Shot was +/- 2-yards from the target yardage[/size]
[size=inherit][/t][/size]
[size=inherit][/t][/size]
[size=inherit][/color][/size]Results
[size=inherit][/color][/t][/size]
[size=inherit][/color][/size]Bottom line:

The "better" angle is not better for scoring. 

For the yardages used in this study, across all skill levels:
  • [size=inherit][/color][/size]Center of the fairway was the lowest score 77.5% of the time
  • [size=inherit][/color][/size]The "bad" angle was the lowest score 17.5% of the time
  • [size=inherit][/color][/size]The "good" angle was the lowest score 5.0% of the time
[size=inherit][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/t][/color][/size]
If you only compare the "good" side of the fairway to the "bad" side:
  • [size=inherit][/color][/size]The "bad" angle was the lower score 59% of the time
[size=inherit][/color][/size]
 If you compare the "good" side of the rough to the "bad" side:
  • [size=inherit][/color][/size]The "bad" side of the rough was the lower score 66% of the time
[size=inherit][/color][/t][/size]
[size=inherit][/color][/t][/size]
[size=inherit][/color][/size]My Thoughts
[size=inherit][/color][/t][/size]
[size=inherit][/color][/size][size=inherit][/color]For shots from the fairway, the center is the best location for scoring almost 80% of the time!

Why? I think it's the Goldilocks principle.

Players tend to be:[/size]
  • [size=inherit][/color]Too aggressive when they have the "good" angle[/size]
  • [size=inherit][/color]Too conservative when they have the "bad" angle[/size]
  • [size=inherit][/color]Not too aggressive and not too conservative when in the center
     [/size]
[size=inherit][/color]The fairway is the best angle to score from 78% of the time. Players are finding the sweet spot between too aggressive and too conservative. They have stumbled into an optimal target.

Note #1
We are typically not looking at huge deltas from one side of the fairway to the other. The biggest deltas are between fairway and rough. 

Note #2
In every situation in this study, being anywhere in the fairway was better than being in the rough.
[/size]
[size=inherit][/t][/size]
[size=inherit][/t][/size]
[size=inherit][/color][/size]What Does This Mean For You?
[size=inherit][/color][/t][/size]
[size=inherit][/color][/size][size=inherit][/color]Is the better angle sometimes better? Yes (but rarely).

Should you intentionally play for the better angle? No.

Playing for the better angle means you need to have a target that is closer to trouble (e.g. rough, bunker, trees, etc...).

Having a target closer to trouble means any benefit you gain from *sometimes* having the better angle is offset by finding yourself in trouble more often.

Does this mean you should try to ONLY center your shot pattern over the center of the fairway? No.

Sometimes the optimal target is shifted well away from the center of the fairway to avoid a bunker or a penalty hazard.

All the data is below.

Thanks again for reading this week! Have a safe and happy new year!

Bret L, Rob, this is about the second shot angles, not the drive angles. The discussion only refers to the drive in relation to how it affects the second shot angle.


Bret L: I stated earlier in the thread that ironically, the type of angle you are referring to (cutting corners to reduce distance) which epitomises the “heroic school of design” may be much more relevant in modern golf than the second shot angles associated with the “strategic school of design” which is the Golden Age bedrock.

Jeff,

Thank you for posting one of the things I was looking for.  And they can't be serious right?  All those conditions had to be met?

What Shots Were Selected?
For a shot to be used, it had to meet the following criteria:
 - Second shot on a par 4
AND
- Fairway was at least 30-yards wide where the ball was
AND
- Hole was cut 6-yards or less from the right/left edge of the green
AND
- A shot on the "side" of a fairway needed to be close to the edge (20% or less of the fairway width)
For example, on 30-yard wide fairway, the ball needed to be 6-yards or less from the side-edge of the fairway
AND
- A shot in the center needed to be in the middle 25% of the fairway. For example, on 30-yard wide fairway, the ball needed to be 3.75-yards or less from the center of the fairway
AND
- No penalty hazards in-play around the green
AND
Shots from the rough were not recovery shots
AND
Shot was +/- 2-yards from the target yardage

I could play several rounds and never incur those precise criteria.  Talk about cherry picking data....this is completely laughable.  Especially when they say holes with hazards around the green are excluded, which is perhaps the primary reason one would play for the better angle!

Only took 9 pages to get here, but thank you!

Hell, you might even get a counter-intuitive result--that scores are lower from the bad angle.
Anything's possible, but say a ball is on the right side of a fairway 160 yds. to a diagnoal green with a middle back right pin fronted by a bunker on that section. For me it's a 7 iron to the middle or front left portion of the green if its the safer play, whereas a pro or even a low single digit handicapper that can crush it will most likely take flag directly on with a pitching wedge, as the trap is little more than a visual impediment to them. Of course, other factors, such as wind come into play, but club selection and one's confidence in their ability to execute certain shots often trumps what playing angles attempt to dictate. If presented the same situation but a 110 yds. away vs. 160, it changes my decision making process entirely, as now I'm taking the flag on given I have a much higher lofted club in my hand.


What directional playing angles can never completely account for are varying ball flight angles and their impact on strategy and decision making. The sad thing with so many golden age courses becoming obsolete for tournament golf is that the original archies didn't design them from a strategic standpoint with the understanding that one day players would be hitting full and flip wedges into the majority of greens.

Kalen,


A lot of the criteria on there are set up to assist angles mattering, not the other way around:


- More than 30 yard wide fairways
- Pins cut tight to the edge
- Shot at side needed to be close to the edge


Etc… There will still be huge data points. Their criteria doesn’t seem obviously set to meet an agenda at all.

Hell, you might even get a counter-intuitive result--that scores are lower from the bad angle.
That's what you often see from the data: let's imagine a bunker short right. The "good" side of the fairway (left) results in slightly more aggressive shots and often more short-sided shots and a higher scoring average (and plenty of people still miss the shot in the bunker). The "worse" angle leads to more conservative approach shots (plenty still mis-hit it into the bunker). The latter often leads to a smaller scoring spread (fewer doubles, fewer birdies) while the former leads to, due to the aggression, more birdies… with more bogeys and doubles.


What I'm getting at is that I play a draw. If I aim down the middle I'm going to spend a lot of time in the left rough or worse. I use angles on the tee box and start line to get my ball in the fairway.
Nobody's (except you?) is talking about start line. It's where the ball finishes.

They should not. Their dispersion pattern is still quite large from 160.

Jeff,

This just takes me right back to my first post on the issue (somewhere in one of the early pages of this thread), where I noted that one of my problems with big data is that it pools very different kinds of holes together, obscuring effects that might exist for some types of holes. I suspect that these numbers would be different on a subset of holes designed for angles to really matter, i.e. ones with angled greens, pitched toward the proper fairway angle, and with testing hazards on the short side. Most of what Lou Stagner has specified in his criteria here is good, except for 'no penalty hazards in play around the green,' which is a big exception. But the criteria can't differentiate holes by the other conditions I've mentioned.

Still, I'm convinced that as a practical matter, we shouldn't chase angles unless there's almost no cost to doing so. That's why I started the other thread. I also agree with Mike Nuzzo's point in his thread about sloping greens and Bret's point about how even if there's no difference or a counter-intuitive difference in scoring, this doesn't mean that angles don't matter because they still might have a psychological effect. So I think that we should be trying to 'break' our finding that the good angle doesn't matter by testing cases in which it's most likely to matter. And if it still doesn't matter, some people might need to rethink their ideas about designing for angles.

But it's also possible that even in this best case scenario, the angle wouldn't really matter because players will be more likely to aim for safety when they have a bad angle and/or get too aggressive from the good angle. Hell, you might even get a counter-intuitive result--that scores are lower from the bad angle.
That's what you often see from the data: let's imagine a bunker short right.

The latter often leads to a smaller scoring spread (fewer doubles, fewer birdies) while the former leads to, due to the aggression, more birdies… with more bogeys and doubles.


I still want to see this for different types of holes as described above. But I'm much less confident than I was when I wrote my first post on this that it would make a difference even in the case of minimal driving hazards and almost completely convinced that it wouldn't make a difference if there's any type of significant driving hazard on the good angle side. You and Lou Stagner have changed my priors, so thanks for replying to my posts.

Brett:


That is a well reasoned and concisely delivered post.


I'd suggest the break down should continue further and differentiate between players with different kinds of ball flights.  Not everyone hits the high ball that stops quickly.  The "when the ball is rolling" disclaimer probably applies to a greater number of players than folks on this discussion want to admit.

Broadly, and as quickly as I can:
And again, nobody's said AFAIK that an angle "doesn't" matter… after you've hit your tee shot. But any discussion of angles has to include the tee shot that gets you there, and whether it's worth trying to achieve that angle over just hitting it into the fairway.

Still, I'm convinced that as a practical matter, we shouldn't chase angles unless there's almost no cost to doing so.
Basically, yeah.

I can say this… Lou and I have the data there, and it mostly shakes out the same… for the same reasons.

Let's do a little math… Let's assume a 160-yard approach shot, and a fairway that's 30 yards wide. How much is the "angle" from the middle of the green different if you're talking about being 4 yards from the left side or 4 yards from the right side? The answer… is less than 8°. A single minute on a clock is 6°, so you're talking about the difference between 12:00 and 12:01:18.
Title: Re: “Angles Don’t Matter”
Post by: Erik J. Barzeski on February 28, 2023, 11:13:11 AM
Also, all y'all are missing the really obvious hole here… amateurs are almost never actually playing golf following my system or DECADE or whatever. Despite rarely breaking 90 (or 80, or whatever), they're almost all just trying to hit the ball toward that stick with the piece of cloth atop.

Edit to add: I'm not saying they're not aiming away from a pond or away from a really bad bunker. I'm saying that they aren't doing it enough. They're not employing any sort of system at all - they (generally, as almost always) under-estimate the size of their shot pattern (Shot Zone) and over-estimate their carry yardages/skill. That 1-minute difference in approach shot angle is swallowed up by the dispersion pattern from 160 yards.

P.S. I chose 160 because it's a distance at which an amateur might be hitting a 7-iron. Any shorter than that and we're not getting into a lot of roll-out, and any longer than that and the angle just gets smaller and smaller. It seemed to me like a reasonable distance.

My take away is angles don't matter ... until they matter .. which is much of the time .. or none of the time .. depending on your angle.

I know you said "might," but there's a wide swath of players who will get plenty of roll on a 160 yard shot (and even less) because they (a) have to hit a club with much lower loft than your hypothetical 7-iron or (b) just don't hit the ball that high.  Some of these people are also deadly accurate with just about every club in their bag.  (Granted, there are plenty of amateurs who can hit the ball high and far, just not wit much control, which seems to cover your way your broad brush is using the term.)


These are the same people that are going to tick tack their way around a course because they never want to have to hit over a bunker or hazard.  They're not just willy-nilly aiming at the flag.


The applicability of the general theory is highly slanted to the playing style of a better player.  But in the general scheme of things, angles are going to always matter for a large class of players.  Their approach to the green might be on their 3rd or 4th shot, but it is still an approach shot.


PS - I know the response here is the "when the ball is rolling caveat," but for a lot of people the ball is always rolling.

Post by: Jeff_Brauer on February 28, 2023, 01:40:27 PM
Sven,


I checked Gene Parent's distance, carry and roll guide, and you are right about shorter hitters.  The 55-75MPH swing speed players will have 20-25 yards of roll on a 160 yard shot, using anywhere from driver to 5 wood. 


So yes, on most par 4 holes, their angle on the second shot matters. On the tee, I presume hitting the fw is all that matters.  The second might be a layup or go for the fat of the green with open front type consideration.  If they are aiming at the flag on the third shot, then their roll under 100 yards is reduced to 8-15 yards (slower swing speed higher)


I'm 68 and have lost a lot of swing speed, and my typical 85-90 swing speed should produce loft of 24 yards/72 feet and roll of 8 yards to hit it 160.  So I would probably have to aim at least 9 yards past any bunker lip, and also consider my lateral dispersion.  I think it still works for many of us senior golfers who can still lift a shot to use the system.  Perhaps on the third shot as you say....(more and more LOL NOT!)

Sven,


I understand that, which is why the bulk of the post is giving typical carry/roll figures for the slowest swing speed players, who typically have more roll.  But, I know a lot of senior golfers like me who still get spin and height.  It seems the really slow swingers are super seniors and women recreational players, probably also of a certain age.  It confirms what you said, and what I believe has long been generally known that many players do need that frontal opening, which is why most architects leave one on most greens.


I don't know that I have the stats on who plays by age or by swing speed, but that would be handy data to have!

I know you said "might," but there's a wide swath of players who will get plenty of roll on a 160 yard shot (and even less) because they (a) have to hit a club with much lower loft than your hypothetical 7-iron or (b) just don't hit the ball that high.
You have read my "disclaimer" about the ball rolling billions of times by now (I may be exaggerating slightly).

Some of these people are also deadly accurate with just about every club in their bag.
It's highly unlikely they're more accurate from certain distances than a Tour player.

The applicability of the general theory is highly slanted to the playing style of a better player.
Not really, no. The strategy stuff holds up into the higher handicaps pretty well. They can't play for angles any more than a lower handicap player. Their Shot Zones are bigger AND they're worse at getting out of trouble.

But in the general scheme of things, angles are going to always matter for a large class of players.
So you're just going with the way of arguing where you just state "this is so, because I say it." 

Strategy becomes less and less important the worse the golfer. What's "strategy" when your Shot zone is 80 yards by 60 yards with a 6-iron? Just have fun playing golf, and try to get the ball in the air and moving forward more often.

Please don't put words in my mouth.  I didn't say that.  But even you would have to admit that an accurate player who hits driver 180 is going to have a smaller dispersion factor than a tour pro that hits it 320.

The applicability of the general theory is highly slanted to the playing style of a better player.
Not really, no. The strategy stuff holds up into the higher handicaps pretty well. They can't play for angles any more than a lower handicap player. Their Shot Zones are bigger AND they're worse at getting out of trouble.


Which is why many of the think about angles even more.  They want to avoid trouble at all costs.

But in the general scheme of things, angles are going to always matter for a large class of players.
So you're just going with the way of arguing where you just state "this is so, because I say it." 


No, I'm arguing this because I see it on nearly a daily basis.  Call it an unintended occupational benefit.

Strategy becomes less and less important the worse the golfer. What's "strategy" when your Shot zone is 80 yards by 60 yards with a 6-iron? Just have fun playing golf, and try to get the ball in the air and moving forward more often.


You continue to use the same broad brush you've used all along.  Not every high-handicapper fits this description.  There are many who can hit a fairly straight shot on repeat, yet they can't get the ball in the air enough to consistently be able to take on trouble head on.  And this is just one example of an outlier from your "average amateur."




There are plenty of other caveats to your general premise, including (a) courses with enough width to make a decision on a side worth considering and (b) playing in wind strong enough to make you have to think about rollout.  I happen to work on courses where both of these factors come into play.  Not every round of golf is played on a soft, narrow fairway, parkland course on a windless day.  Not every fairway is only 30 yards wide.  Not all rough is bad to play from.  And not every shot is going to stop on a dime.

You're talking to someone who has to offer suggestions on where players should attempt to hit the ball thousands of times over a week.  My data set is pretty solid.  There is no cut and dried rule of thumb for every player or every shot, everything is situational.  Much of the time, depending on the player, the conditions, what kind of round they have going, where things stand in a match or just on that hole and the lay out of a hole, it absolutely makes sense to think about setting up angles.

But we're talking in circles here.  You keep on believing what you think the stats are telling you, and I'll keep on going with what my on course experience has taught me.
Title: Re: “Angles Don’t Matter”
Post by: Jeff_Brauer on February 28, 2023, 05:23:46 PM
Sven,


I think the point of the stats is that Tour Players (to start) aren't as accurate as we tend to think.  How can we expect average players to be?  You might experience one player with 14 tee shots, and you might conclude that he is pretty accurate, but it's not a statistically valid sample, even if you caddy for them 3 days in a row.


I think tour player dispersion to contain 2/3 of their shots is about 10% of shot length, scratch players about 11.25%, and bogey golfers are right at 15%.  I think the stats guys probably tell their clients to use 80-90+% plus (obviously you can't plan on hitting one of your worst shots ever, or you would likely be too conservative) to pick their line.  I think they recommend drivers not be hit unless the LZ is over 65 yards wide, which is 21.67% of 300 yards.  If the ratios hold, I suspect that is about 22% and 30% for those lower level players.  As you note, due to the shorter length of tee shots, 30% of 200 yards is 60 yards, so yes, they need an equal or slightly narrower corridor to really tee it up.  (Now, that is handy for designers.....)


Sure, some are a bit less or more, but I doubt your "dead straight" decent am is much less than, say, 90% of average dispersion.  At 160 yards, to use Erik's example, he would probably tell a scratch player to play for a dispersion of 15-20% or 24-32 yards, or 12-16 yards from the key hazard, if any.  For a bogey golfer, probably about 48 yards, or 24 yards from the key hazard.


Just asking, but how do you advise your line of play to a first time C or D player at Bandon?  And yes, I think all systems or ideas would account somehow for the wind, etc.  But, are you comfortable after a few holes telling the player to aim at the flag on certain holes?  Or to flirt with a fw bunker by playing less than 30 yards from it to gain an advantage?  I know Erik wouldn't be.  It would illustrate to me just how much more conservative he is or how much more aggressive you are as to lines of play.


Again, I think the stats world would just tell you that over the course of a week or season, playing more aggressively would cumulatively lead to slightly higher scores.  And, let's face it, while I enjoy taking the risk sometimes as well, overall, higher scores generally lead to unhappier golfers.


As always, just my take.

Jeff: 


Trust me Jeff, I know exactly how inaccurate golfers of all levels can be.



I couldn’t begin to give you a general answer as its all situational, as I noted above.  Does the guy miss right or left, can he get it in the air, is there an easy carry or is it pushing the capabilities, is it the end of the day and everyone is getting armsy? 


But there are plenty of times where I’m asking a player to favor one side or the other of the fairway for a very specific reason.  And not every shot setting up an angle is necessarily any more agressive than other options.  Its sometimes just the better play.


If you want a bit of a breakdown see the conversation on 8 at Pac on the other thread.  Just off the top of my head, you could add the following to the list of holes where position makes a difference:


Bandon - 1, 4, 7, 8, 10, 11, 16 and 17.


Pacific - 1-4, 6, 8, 9, 12, 13, 15, 16 and 18.


Trails - 4, 7, 13, 14 and 15.


Old Mac - 1, 6, 7, 10, 11, 13, 14, 17 and 18.


Sheep Ranch - 2, 4, 6, 8, 10, 13, 15, 17 and 18.


The problem with the premise is that it will be looked at as a general rule.  Part of my job is knowing when the risk is worth taking, after examining all of the factors.


For many players, playing extremely safe is the only way they’ll finish the hole.  Fir some, sometimes you just have to be Joel from Risky Business.

Sven,

You're relying on your experiences. I'm relying on the data from millions of shots.

Are there accurate amateurs? Sure. I've talked about how my own daughter will play to angles on holes where she has a longer shot in. I've never said there aren't exceptions.

I think we disagree on how frequently they occur. And on the definition of "data" since yours is likely just your recollection of what you think to be true.

Have a good day.

Ben,


You are probably right.  There are many ways to view and assess golf and architecture, some falling in the older, somewhat romantic view, but more and more, IMHO, many adopt more scientific views as time goes on.  It seems to be human nature to try to understand things better and better,i.e., medicine has progressed from bloodletting, to surgery, to micro noninvasive surgeries, etc.


I remember a lot of blow back when Jack measured courses, vs. Sam Snead and that generation playing by eye.  Again, in my view, if you use a yardage book you have accepted a certain amount of new style tech in making your shot selections.  It's just that the newer versions of those now consider more than the distance to flag and front edge, they are considering likely shot dispersion.


And in fact, the idea that lower scores are best achieved by hazard avoidance is not new.  JN has said that for years.  The idea that more GIR is the quickest way to lower scores also isn't new, nor the idea that you are much more likely to attain GIR when hitting from the fairway (in most cases)


In reality,  Sean and Erik aren't that far apart and both have the mentality to help "their" golfers.  Perhaps it should be said that angles do matter in architecture, it's just that we now know that most golfers really aren't able to actually master them, and take advantage via their golf game when they have a good angle. 


Again, IMHO, golf has probably evolved as it should or had to, and literally, billions of golf rounds have shown that hitting fw and greens is both hard and usually more profitable than risk taking.   


The debate about what that means for architecture could seemingly be done without being really personal. 


The good news is, no animals are hurt when using either classic design principles or some new tactic. ;D

I agree that at least from my perspective, it's about time to let it go because it's clear to me what the remaining questions are and that they apply at best to a small percentage of cases.

Maybe it's fair to characterize some of the responses to Lou and Erik as blowback, but we're being confronted with new findings that challenge some pretty strongly held conceptions that are based on pretty good theories. It's not surprising that this generates strong feelings. Some of us may be overdoing it a bit with the rhetoric, but I think most of us are honestly trying to figure out where the new findings leave us and what remains of the topic. There's nothing wrong narrowing the theory and pressing for evidence about special cases of it. That back-and-forth between theory development and empirical tests is a core part of scientific inquiry.

I think it's good that principles of golf architecture are being subject to tests. I'm not sure that Lou Stagner cares much about golf architecture but if not, I hope that someone who does (and has access to Arccos data) will investigate other long-standing golf architecture theories.

Brett,


I have seen the as yet unreleased USGA Distance insights project.  One takeaway is that while architects like to give strategic choices, like "should I feather it into the back right pin position or play for the middle?"  in reality, average golfers simply bail out at surprisingly (to me) short distances.  The 175 yard par 3 with a pond really presents no choice for the average golfer, as they tend to bail out at much over 145 yards.  Ponds near greens probably ought to be restricted to very short holes or approach shots.


That's another thing that has changed in modern golf.  The calculus isn't whether to risk a stroke by firing at the flag. Risk today is more defined as, "I'm not taking the risk of losing another $5 golf ball."  ;)

Great analysis, Jeff and there's a lot of truth to this. I plead guilty of the crime myself, as I've intentionally avoided carries over water even when I've had a decent angle to the pin for fear of losing another $5.00 ball in a round, when I'd already lost two prior. When you pay $50.00 - $75.00 for a round of golf and lose 3 or 4 balls in the process, it becomes an expensive day.

I think it probably bothers many here that the USGA and RTJ in 1951 were actually right......they knew the designs of those Golden Age courses really weren't cutting it.


Wasn't it Flynn who (or was it Langford?) that design should favor accuracy, then length?  Turns out, he had it backward.......and RTJ designed courses that demanded both from tee shots.

Brett, Mark, Ben and Jeff:


Thanks for your dose of sanity in the last round of posts.  If not a termination of the thread, perhaps a reset is in order.


My main issue, as someone mostly in the angles matter camp, has more to do with the study itself.


Correct me if I’m wrong, but the shots examined exist only in the vacuum of approaches from different locations.  There isn’t any connection to how those shots got to either the good side or the bad side.  For example, are a number of the bad shot pinpoints the result of the player aiming to the good aide, but knowing if they missed to the other side of the fairway they’d still be in play.


Its the concept of only examining one segment of the play of the hole that doesn’t sit right with me.  When you stand on the tee, often you just plan on how to keep a ball in play on that shot, but many times you’re thinking about how the entire hole will play out.


I’d be interested in seeing a deeper breakdown, one that encompasses all of the nuances above.  It seems to me that where people were trying to get to with their tee ball is an important variable that hasn’t been brought into the equation.


The gist of the theory we’re talking about is that because golf is erratic, it is always better to play safe.  But sometimes you have it, and two shots are going to go pretty much like you planned.  Part of the skill in this game is knowing when you’ve got it going, and when you don’t.


The other factor not discussed is tee ball club selection.  I’d like to see a breakdown of less club on an aggressive line versus more club on a safer line.


And of course, all of this needs to somehow account for the other variables such as wind, firmness, trajectory, etc.


All the best,


Sven

That's kinda beside the point. And Lou's data, my data, etc. is an amalgamation of thousands or millions of shots across many, many holes.

The primary goal on almost any tee shot, heck, any shot of any kind is to advance the ball safely. That means if there's bunker in the right side of the fairway and light rough to the left, a smart player looking to shoot the lowest score overall will take that into consideration and, generally, aim toward the left-center.

Whether their ball ends up with the "better angle" near the bunker in the fairway or in the left side of the fairway with the "worse" angle is irrelevant: as we've said a few times, they shouldn't be playing toward the bunker much anyway.

If I'm "aiming" down the middle of the 9th hole at Pine Needles, I'm not going to be there all the time. My shot pattern will look somewhat like a bell curve… the middle 68% will be in the fairway maybe, 95% will be in the "corridor," and maybe (hopefully less!) 5% will be outside the corridor left and/or right. Maybe the bell curve will be "leaning" one way or the other… but I'm still looking to get as many of my shots as I can in the middle of the corridor.

The gist of the theory we’re talking about is that because golf is erratic, it is always better to play safe.  But sometimes you have it, and two shots are going to go pretty much like you planned. Part of the skill in this game is knowing when you’ve got it going, and when you don’t.
We have data on how often players "have it." I think you'd lose any related bets here, but…

Do players feel like they have it sometimes? Yes. But we also don't hear very often from the player who feels like he has it… then hits a lousy shot. On the Tour or in our personal lives.

I shared that with Lou and he said: "Tell me you don’t understand anything about probability without telling me you don’t understand anything about probability."

My conclusion is that both Erik and Sven are correct. When you look at millions of data points that flatten out particular factors such as weather and player capability on a given day (and excluding when the ball is rolling), the probabilities say that angles do not matter for scoring. However, when you are looking at an individual golfer on a particular course, those factors may overcome the overall probabilities. Not for all rounds and all courses/holes, but for enough to matter, even when the ball is not rolling (which as an aside is an exception that swallows the rule on links courses).


But at the end of the day, Hogan, as he often does, proves why both Erik and Sven are correct. The 11th at ANGC (yes, I know that it is not about a tee shot chasing the angle) and the 6th at Carnoustie. Probabilities rule over the long term, but genius is genius.

Okay, let's try this. Now, I know it's not average players, but here is shot data from all shots 180-219 in the fairway at ANGC's 11th from 2019-2021. There are 91 shots on the "B" side of the line (the line may not be exactly right - it's shots closer to the left side of the fairway than the right) and 86 shots from the "A" side.

(https://p197.p4.n0.cdn.getcloudapp.com/items/X6uKrgyD/914a8804-90fc-4fe1-ba12-5e5645145ada.jpg?v=28cc29ff8de1e94a4beac84943f8aaa5)

As you can see, only the hole locations close to the water were used to accentuate the angle.

Take a guess what these factors are from A and B:

Stat                 A         B
----------------   -----     -----
  Scoring Avg.:
         GIR %:
Avg. Proximity:
    % < 40 ft.:
    % < 20 ft.:

What is the difference in the lies between the A side and the B side.  Where are you more likely to have a hook lie.


Do the stats account for every variable?

And here’s the crux of it.  There are a ton of variables in this game.  Lies matter, perhaps sometimes more than angles.  Wind matters. Trajectory matters.

But at the end of the day, Hogan, as he often does, proves why both Erik and Sven are correct. The 11th at ANGC (yes, I know that it is not about a tee shot chasing the angle) and the 6th at Carnoustie. Probabilities rule over the long term, but genius is genius.
Okay, let's try this. Now, I know it's not average players, but here is shot data from all shots 180-219 in the fairway at ANGC's 11th from 2019-2021. There are 91 shots on the "B" side of the line (the line may not be exactly right - it's shots closer to the left side of the fairway than the right) and 86 shots from the "A" side.



As you can see, only the hole locations close to the water were used to accentuate the angle.

Take a guess what these factors are from A and B:

Stat                 A         B
----------------   -----     -----
  Scoring Avg.:
         GIR %:
Avg. Proximity:
    % < 40 ft.:
    % < 20 ft.:

If you don't want to fill out the chart with actual guesses, just guess which one was higher or lower.

Edit to add this: 199.8 average from B, 199.3 average from A.

Glad to hear that Lou wants to join the site! Looking forward to more of these types of conversations.

This would be a good case to get a bit more sophisticated with our data analysis, which would allow us to address some of the issues that have come up in this thread, like conditions and how well the player is playing. The outcomes that you've specified are good, as is the focus on left pins, although I'd be especially interested in the results for the back-left pin, which is where the angle should matter most.

I would run regressions of your outcome variables on distance from the ideal point in the fairway, let's say 2 yards from the right rough. What we should find is that the further you get from the ideal point, the higher the scoring is.

I'd control for a variety of things. First, I'd drop all observations from the rough. I don't know if there's data on the slope of the fairway from all points but if there is, you could control for this. You could control for wind generally, but probably not the exact conditions when the player played their shot. Most important, you could control for how well the player has been driving the ball up to this point by using strokes gained driving either for this tournament or for the year--because those up the left side might be driving the ball worse than those up the right side and we need to separate this out from the pure effect of the good angle. You might also want to control for strokes gained approach to separate out how well the player is playing with their irons.

That's a cop-out. Everything you're saying right now is a cop-out. If angles matter on the 11th at Augusta National in the Masters, then they matter. If the other things all matter so much more, then angles really don't here.

My question after eleven pages is how much of the “data” is a revelation versus what you already know from experience? Isn’t a fair amount of the information just common sense dressed up as “millions of shots” leading to the conclusions put forth by the proprietors? Finally is a manifesto required for the amateur player to succeed with the scorecard?

Erik:

Not a cop out.  You just picked a bad example.  There are way too many factors going on at 11 for this exercise to have any validity. 

Probably most importantly, the strategy at 11 is to hit it far enough to get to the speed slot, thus getting some extra rollout and a shorter club in your hand, which makes a big difference on this hole.  11 is an example of where a long ball on the safest line is most likely going to result in better results.  Perhaps you can break this one down for every drive under 300 and every drive over 300, and we'll see how it plays out. 

And there are a bunch of other factors here that need to be looked at.  Where the pin is for each of those shots also makes a difference.  What the wind was doing on each of those shots makes a difference.  Augusta might not be your best example, as many of the shots are played for a lie, not necessarily just an angle (go read Damon Green's breakdown of Zach Johnson's strategy on the course). No one wants to be hitting into 11 (or many of the other holes there) with a ball way above or below their feet.  If you want to pick a hole to examine at ANGC, perhaps 18 would be better.

I'd like to see a study that tracks not just one shot, but the entire play of a hole.  Set it up for a variety of different classes of players (those that primarily hook the ball, those that fade, short hitters, long hitters, etc.).  Break it down on whether it was into or with the wind.  Throw out any instances where someone ends up in a divot or gets some other bad break.  And run control groups for those playing for an angle, and those playing the safest line off the tee.  Do this on longer holes and on shorter holes.  Do it for holes where the best perceived approach angle is near a hazard, and when it is away from a hazard.  Do it for holes with water, and holes where you're just negotiating bunkers.  Do it on 30 yard wide fairways, and do it on 100 yard fairways (there are a few of those out here, believe it or not).  Have people hit a few different clubs off the tee if doing so is going to take tee ball trouble out of play (either long or short of it).

Do it for one player only.  Because isn't that really the issue?  How is that individual player going to fare?  What use are stats for the atypical golfer?  Not every player is going to have the same ideal spot, so how can you decide if a pinpoint is actually in the proper category?

Or just hire a good caddie. 


“On the approach, the left hole locations are closer to the water but are easier to deal with because bail-out shots to the right still find the green. It’s those middle-right hole positions that are the most difficult. You don’t want to play left of them because of the water, but if you miss the green right, you have a testy chip. If the ball rolls more than three feet past the hole, it’s likely to go another 20 feet past.”

I think theres an argument to be made that with 630M shots (and counting) recorded, that variables like lie, wind, and trajectory are aggregated and taken into account. That seems to be the opposite of static wouldn’t you say? It’s an evolving and living collection of data.

In my job, we talk a lot about the lowest level of acceptable risk. That risk assessment is absolutely not a static determination. It is a safety mindset taken in aggregate of all the factors and it can be calculated.

I don’t see how using golf analytics for decision making on the course is much different.

And you know as well as I do that they don’t take into account those variables.


What I am arguing is that due to the sheer amount of data, it is already aggregating lie/wind/trajectory. Do you think the shot tracking only tracks when it’s flat and windless?

I didn't pick the example. Ira did (IIRC). And it is a cop-out, because your new plan is just to apparently claim "too many factors going on." Well, if there are too many other factors that affect this, when are those NOT a factor, and where does "the angle" rank in that list? Because, if it's way after whatever you listed (and some things you probably didn't list), then I'm again going with "don't matter much at all*."

There were likely good lies of the 86 shots on the one side, and good lies on the 91 shots on the other side. And bad lies on both sides. And so on. "You Cannot Reason People Out of Something They Were Not Reasoned Into"

Probably most importantly, the strategy at 11 is to hit it far enough to get to the speed slot, thus getting some extra rollout and a shorter club in your hand, which makes a big difference on this hole.
These are where most people hit their tee shots on #11 (that hit the fairway).

11 is an example of where a long ball on the safest line is most likely going to result in better results. Perhaps you can break this one down for every drive under 300 and every drive over 300, and we'll see how it plays out.
What's that got to do with angles? Let's say we look at tee shots that left 140-180 in to the green. You know what you'd see? Way fewer tee shots. Lower scoring averages (duh), more GIR (duh), more shots inside 20 and 40 feet (duh).

This is where many players hit their tee shots. And on a longer shot, the angle should matter more, because the ball will not be flying and stopping as quickly, and it's a more difficult shot anyway with a larger Shot Zone. What you proposed has no value at all and is not on topic here at all - it's just talking about players who had a shorter club in than other players.

And there are a bunch of other factors here that need to be looked at. Where the pin is for each of those shots also makes a difference.
They're all the left pins by the water. The hole locations that exaggerate the effects (supposedly) of the angle with the water right there.

They're realizing that they need to avoid penalties (bad bunkers, trees, horrible rough) first and foremost, try to get it in the fairway second, and forget anything else, really.

Tour players aren't often "attacking" pins — regardless of what you hear on TV — from 180 out regardless of their lie or the wind or anything like that. They're just not. Especially with water close by. Do you recall where Scottie — to a right pin — hit his second on Sunday? Short right. Because a bogey doesn't kill him, but a double or triple might.

Those factors might affect HOW you play a shot (into the wind maybe you hit a knockdown 8, downwind maybe you rip a PW for the height and spin, etc…), but they don't really affect the "angles" — they don't affect where the optimal center of your Shot Zone is and thus where you're trying to put the ball.

The short answer is that 11 is one hole that players don't think about an angle.  They think about staying safe off the tee.  These were factors specific to 11.

There were likely good lies of the 86 shots on the one side, and good lies on the 91 shots on the other side. And bad lies on both sides. [size=78%]And so on.[/size]

What's that got to do with angles?


Nothing, it has to do with the strategy that players (specifically Tour Players) take on this particular hole where I've already stated they don't play for an angle off the tee.


Let's say we look at tee shots that left 140-180 in to the green. You know what you'd see? Way fewer tee shots. Lower scoring averages (duh), more GIR (duh), more shots inside 20 and 40 feet (duh).


Are the "duhs" necessary?

This is where many players hit their tee shots. And on a longer shot, the angle should matter more, because the ball will not be flying and stopping as quickly, and it's a more difficult shot anyway with a larger Shot Zone. What you proposed has no value at all and is not on topic here at all - it's just talking about players who had a shorter club in than other players.


Which is entirely what the players want.  Here's Larry Mize on the 11th - "[/size]“With the tee shot. There’s a point in the fairway, if you can reach it, where you can get a little more run and get a shorter club in your hand into that green. Makes a big difference.”[/color]

Again, you're the one who wanted to talk about angles on 11.  I said it was a bad example.


And there are a bunch of other factors here that need to be looked at. Where the pin is for each of those shots also makes a difference.



They're all the left pins by the water. The hole locations that exaggerate the effects (supposedly) of the angle with the water right there.


See the Jordan Spieth quote at the end of my post noting the middle and right pin positions are harder.  But then again, no need to digress further on a hole where the players don't play for an angle.

What the wind was doing on each of those shots makes a difference.
Those come out in the wash.


Does it?  If there's anywhere on earth where a sudden gust of wind can seemingly change fortunes, it is probably Amen Corner.

How do you know there isn't a difference in the results if you haven't run the study?  You expect there's a difference, but you don't know it.

Provably wrong.  There are many instances, including on Augusta National, where they are playing for an angle.  The layup on 15 is one glaring example.

Let's take an example that I know you know - 14 at Trails.  And we'll play it in the winter so that it is into the wind (so we're not worried about excessive roll).

Sven


For the 305 tee I will be aiming essentially at the front of the green. Slightly front right if we are being exact.


I know I *should* be on the left side. But my dispersion is wide enough at 250yds or so that if I aim for the upper left side of the fairway and tug one, I’m in the woods.


This is for me, a 12 index with above average club speed. A pretty average golfer I’d argue.

Is your normal miss to the left?


What should the average golfer that fades the ball do?


What if the wind was out of the southeast?


Do you like your chances from low right, where anything in the middle is going to feed, to a middle or back pin?


What if you were four down in a match and your opponent had just piped one down the left side?


Did you think about hitting something shorter off the tee leaving a little longer, but very doable approach, from a better angle?

Sven,


I can’t see where any of these factors would cause me to change club selection or aim point.


Actually, check that. The fade one would. Good players tend to miss the ball equally left and right of aim point. Average players and worse tend to miss to one side more often, and that’s usually the fade side (right miss for right handed golfers). It may be useful to aim a bit further left in that scenario.


Other than that specific case, I’m not adjusting my “dead middle of the corridor” aiming point for any of the other variables you raised. Why? The widest point of the fairway is around 75 yards and the corridor itself is perhaps only 10 more on either side. My dispersion with a driver or 3w are pretty similar, and easily fills up that 90 yards. My best case is to aim center mass, allow for variance, keep the ball in play and try to make par.
Title: Re: “Angles Don’t Matter”
Post by: Sven Nilsen on March 05, 2023, 10:42:40 AM
To analyze a bit further, your target spot is actually in the left half of the fairway (at 250 off the tee).  The fairway is over 60 yards wide at that point.  I don't know how wide your specific dispersion pattern is, but aiming a bit further left (say at the front left corner of the green) isn't going to hurt you much, its a minute adjustment.


It really takes a bad pull to get into serious trouble here.  It happens a fair amount of the time because people get greedy, try to get to the green even when they can't (or for the weaker players worry too much about the carry), and end up pulling through the ball too much.


If you manage to find the left half, where your approach is aligned with the green, you really have three misses to most pins - a little short, left and a little long.  From the right side, you only have long and left.  Anything short or right on that line is going to leave you one of the toughest pitch shots on the property.  [As an aside, for a front pin, I don't mind the right side, as the angle isn't as bad and the contours work for holding the shot.]


With respect to your lowest level of acceptable risk concept mentioned earlier, bearing in mind that we're playing golf and not flying a plane, I'd take the slight adjustment to the left on my target line with the hope of increasing my odds on the second shot.  In the grand scheme of trying to make par here, which is my goal every time I play the hole, I know I'm much more likely to make a bogey or worse from a tee ball right of center.  On this hole, on the tee, I'd be analyzing and balancing the risks associated with both the drive and the approach.  To me, a slight risk on the drive outweighs a greater risk if I'm out of position on the 2nd shot.


Now contrast this with 6 at Pacific, another short par 4, this one even wider at about 90 yards in your 250 landing zone.  If you played dead center of the fairway, left of the right side fairway bunker, you're going to be left with a pretty tough angle, sideways on a narrow green, with a quartering wind angle (or dead downwind in the winter to a narrow landing area).  In order to get to a position that is aligned with the angle of the green, you have to play over that bunker, bringing the right side bunkers by the green into play, and even possibly the tree line right of the fairway.  Is the risk worth it?


Doak takes a different approach here.  He takes less club and tries to play as close to the fairway bunker as possible to avoid the contours further up in the middle that feed a ball left.  He is going to take the risk of being near the bunker because he's comfortable with an approach from 100 to 120, not on the absolute best angle, but a better one than if he advanced the ball further and it fed further left. 


These are totally different risk calculations than you get at 11 at Augusta.  11 isn't the narrowest hole on the course, but the real premium is on finding the fairway (as Erik has clearly shown).  Where 11 gets really tricky is not because of the water, it is due to the contours at the front right of the green that can deflect an approach either left perhaps onto the green or right of the green leaving a tough up and down.  A difference of only a few yards on your approach can lead to drastically different results, and its part of the reason why pins on the right side of that green can be as tough as pins close to the water.  Because of this, I don't think there's really a preferred side to the fairway, as wherever you are its going to take an almost equally good shot to procure a good result. 


If anything, this snapshot of three different holes just emphasizes how situational every shot can be.  And yes, I understand that many of the variables that can come into play mean a player should be adjusting their target zone appropriately.  But sometimes, just playing for a safe target zone with minimal risk is going to bring into play much greater risk on subsequent shots.  It is the balancing of those risks that I'm trying to get at when I talk about playing out an entire hole while keeping angles in mind.  Holes like 14 at Trails and 6 at Pac (along with a ton of other holes out here) ask you to make decisions on the tee, and its those kind of holes that make this game fun.

And let's add in one more example on a much different hole than 6 or 14.


How would you play 16 at Old Mac to a right side pin?  Assume normal summer wind off the left and you're hitting from the 435 green tees.


Now play out the same hole from the 408 box as if you were someone who hits a low trajectory ball and maxes out driver at around 170.

My dispersion with a driver or 3w are pretty similar, and easily fills up that 90 yards. My best case is to aim center mass, allow for variance, keep the ball in play and try to make par.

Variance is an interesting concept.  As Erik will tell you, for left and right misses, across a broad range of players, it is probably going to look like a Bell Curve.  For individuals it is going to be a bit more one sided.  One aspect of variance is misses short and long, which we haven't discussed much in this thread.  On both 14 and 6, due to the narrow nature of the green, distance control becomes equally important to direction when you're talking about the approach shots.

I can’t see where any of these factors would cause me to change club selection or aim point.


Actually, check that. The fade one would. Good players tend to miss the ball equally left and right of aim point. Average players and worse tend to miss to one side more often, and that’s usually the fade side (right miss for right handed golfers). It may be useful to aim a bit further left in that scenario.


Two quick points here.


I'm surprised you don't adjust for wind angle, even if it is a small adjustment.  Especially if you have a predominant fade or draw.


Second, in this instance, we are talking about your misses.  What the misses are for the average "good player" or average "average" player shouldn't matter.  We're talking about you.


Sven


PS - The stats will tell you good players miss slightly more to the left than the right, but on average, anyone over a 5 is going to miss more to the right with the difference getting greater as the handicap gets larger.  But then again, these are averages, and not the numbers for individuals.  If we based everything off of averages, every player over a 5 should be aiming in the middle of the left half of 14.

If at the end of the stats say playing angles don't matter or have a huge bearing on decision making for the majority of golfers, I totally buy that. Which isn't to say they don't matter at all, but perhaps not as much as some presume.


The average golfer in the U.S. today doesn't have a great or even good understanding of the role design strategy plays in decision making and the extemporaneous factors (wind, lie, temperature, etc.) that affect scoring. It's better golfers that typically have that knowledge and appreciation. For most guys (and gals) I see hacking it around courses, it's a "hit and chase" game for them. Things such as lie, wind, hazard location, pin position, etc. rarely factors in club selection or decision making. Wherever the middle of the fairway and pin are, that's where they're aiming - yardage be damned!


While the average handicap for men in the U.S. is around 14, it's a median average. Which means for every low single digit handicapper out there you have equally as many around 30. I'd argue the vast majority of the 25 handicap and up crowd have little understanding or care regarding proper playing angles, conditions and strategy. They're happy to make solid contact with the ball and hope it goes straight. Lump this group in with the those who don't maintain a handicap (which outnumbers those that do), in which the vast majority would be high handicappers if they did report scores and you can easily see how the data supports the hypothesis that playing angles don't matter or are overrated at best to the average golfer.

Sven,

Four posts, lots to unpack here. I probably won’t touch on everything you’d like me to.

My only par on 14 at BT is from way down to the right, maybe 240yd tee shot and damn near in the woods. I hit a wedge at the front the green, away from the right green side bunker and it went into the small swale on the left of the green. I two putted from there. Every other tee shot I’ve had there went left, either up against a tree near the bunkers on edge of the woods or in the bunkers themselves. All of those resulted in bogeys or worse. Anecdotally, I think this is a fantastic example of why angles are important.

As for 6 at PD, I’m aiming a smidge off the left of the fairway bunker with a reliable 230-250 yd club in hand. I have no issues carrying that bunker, and my dispersion with a hybrid or FW wood should keep me in the hole. There isn’t a single variable I can think of that would change this tactic off the tee. Pull it long, but in the fairway and looking at the big bunker in the hillside in front of the green. Not ideal but still in the game. If I get lucky and push it over the bunker, I’m in the catbird seat. I’m hoping my opponent wouldn’t be so prudent.

After reading your posts, my opinion is that you are undervaluing the concept of dispersion and variance. My dispersion is so wide with a tee club that the only course of action is to aim for safety. With my length, safety off the tee provides me with a really good chance at par and bogey. In fact, I’d say that the percentage of my double bogeys or worse that come after a safe tee shot with the ability to play for the green (on a par 4) is very low. And by comparison, my dispersion with short irons and wedges is low compared to driver and hybrids. I can be much more exacting (again, in comparison) once my tee shot is “safe”.

I am speaking anecdotally of course. This is my experience. I’m trying to use the concepts of variance and knowledge of my own game to my benefit. I am often surprised at how often golfers allow variables to change their process of thought and execution. That doesn’t mean I don’t want the thrill of great architecture though. We are talking about SCORING. Not the experience or the fun or thrill. I hope architects never care about my or anyone else’s score.

This paragraph is important to the discussion, because I think it changes the discussion (at least for me).


To me, angles matter most if you are trying to get close to the hole to make birdie or par, and less (on the majority holes) if you are only trying to make bogey.  Once you get to the 10-handicap player who is just trying to make par or bogey, it becomes obvious that a safe tee shot is more important than an angle, to a guy who's only going to make one birdie per round, maybe.


But in fact, most architects since the Victorian era have been quite happy to let the average golfer play safely and make a bogey, so that's not really news.

At a certain point, that person playing for par or most likely bogey is going to be even more concerned at angles.  They’re going to want clear shots into the greens just for the comfort level.  It might take them two shots to get to that angle of approach, but it is still the best play for them.

Just to add to Sven's comments,

As a high capper, my overall scores notably improved when I intentionally played for angles, not because i made more pars or birdies, but because i made far less double bogeys and worse.  I will take a ball in rough any day from a better angle over an approach shot from the fairway where I have to fly it over deep bunkers, water, or hit into a side or down sloping green.

Increasingly for me - angles are becoming important for second shots on long par fours and some short par fives.  You can potentially change the angle 360 degrees on such holes (compared to maybe 2 degrees if you are in the fairway off the tee on a par 4).  The difference between a flop shot over a bunker vs. a pitch and run with plenty of green available sure seems to matter to me.

Charlie,

That's been one of the main points of contention.  When Jeff posted the criteria several pages ago, it didn't take into account holes that had water hazards, par 5s, or even par 3s where you may set up one side of the tee box or the other.  And there certainly wasn't any controls that factored in weather, fairway slopes, preferred shot shapes, particular weakness or strengths of ones game, etc.

And the emphasis on scoring has been all one sided, about making a good score with par or better, and forgetting about mitigating risk in trying to avoid worse than bogey.  If you look at the difference in what happened for a player who shot 88 one day and 94 the next, I can almost guarantee the story is found not in pars or birds, but how many doubles or worse did they take.

I can’t make the argument for why the tweet isn’t a great quote any better than this. The aggregate data misses the details of who is hitting the ball and what they’re trying to do.


Of your courses, I know Ballyneal best. Speaking to your point about making bogeys, even as an average to poor ball striker I do a good job tacking around the more penal bunkers. On my last trip I can remember one bunker shot in three days. That’s not uncommon in my memory.


The funny thing about all of this angles and safe tee shots talk is how often I don’t aim for “center mass” at BN. Sheesh, off the top of my head I’m usually aiming off the center of the fairway on 1, 6, 7, 8, 10, 12, 13, 14, 17, and perhaps a couple others.

I’m thinking this is where the difference in our thought process resides. I don’t think there’s many points (acknowledging there are some) where the bogey golfer is as concerned about angles as the plus golfer. Getting the ball down in three is such a different proposition to getting it down in five. Speaking about the 14th at BT, I’d venture a guess that the tee shot distribution for bogeys is very even…spread all around. I’d also guess that the tee shot distribution for birdies is mostly located on the left of the fairway.

A scratch golfer makes ~3 birdies a round and a 15 handicap makes ~1, if I remember correctly. Doubles or worse is way more lopsided. So basically you’re right. The difference between a stick and a duffer isn’t the birdie, it’s bogey and double avoidance.


Like Tom said and I agree, as it applies to angles and this discussion, the path to double bogey avoidance is pretty universal in golf architecture.

As I described, they tried to use holes that were similar par 4 holes, without a 2 stroke penalty hazard, 30+ yard wide fw, etc.  I have had this discussion with several more techinically inclined architects than myself regarding ball dispersion.  Some think the tests ought to be tightly controlled on a range, etc.  I tend to think that real results out in the "wild" probably end up being very representative, over the controlled tests.  Neither side is wrong.


The bogey to birdie stats are about right.

Jeff,

I think we can certainly agree that the testing component needs to be far more controlled over just selecting millions of shots and drawing inferences from them.

P.S.  I looked back at your post, and perhaps the most "interesting" exclusion was this one:

Shots from the rough were not recovery shots
AND
Shot was +/- 2-yards from the target yardage


If i'm interpreting this right, this means any shot from the rough needed to A) at least have intent to finish somewhere on the green AND B) finish + or - 2 yards from the target yardage.  I struggle to understand this one because even for a tour player, how often do they hit a shot from the rough at say 100 yards or more and have it end up within 2 yards of the intended distance?  Much less an average player who may do this once in every 100 shots from the rough? 


And it begs further questions, like how many times was a player coming in from the rough, from a bad angle, and didn't execute to two within 2 yards and their data point is now excluded?  It would also exclude a data point where someone hits it from the rough, from a good angle, but instead of ending up in a bunker or a water hazard, they end up on the fringe and salvage a bogey at worst.  Or what if missing in the rough affords me with a good angle for a simple recovery shot where my next shot will be a simple pitch as opposed to a difficult lob wedge over a bunker as Jason pointed out.


This one criteria alone could easily be excluding millions of potential data points, (much less other results on par 5s, or holes with hazards, etc )and give serious pause
to doubt the reliability of the conclusions..

Post by: Jeff_Brauer on March 06, 2023, 04:07:33 PM
Kalen,


While I can't be sure, I think the 2 yards would be from the edge of the oval of the expected target pattern.  From 160, that might be an oval 24 yards wide and almost as deep, depending on handicap.  Yes, getting 2 yards from the pin would be a lot to ask from the rough. 


Lou's stats did include the average score from the rough on both the right and wrong side of the fw, so I think that is covered, but again, I do tend to think measuring a wide swatch of shots in the real world is probably valid.  I mean, no golf shot is ever in a real controlled situation anyway, so what validity does putting the test in an ultra controlled situation have?  It is what it is.  Maybe the next 580 million shots would have a slightly different result, but I doubt it would be major.


And, as I tried to explain, they did try to control by concentrating on par 4 holes of similar characteristics.  I'm not sure what more control anyone would want, but I understand the idea behind it.


Lastly, in a separate, unreleased USGA study, they asked average golfers if they changed their aim if there was water in play.  They said they didn't, but the USGA had cameras and data collection on each shot, and in reality, they really did, even if they didn't realize it.

Post by: Kalen Braley on March 06, 2023, 04:22:13 PM
Jeff,

That would make a lot more sense, if it actually was the target "pattern".  I hope further clarification comes because there are certainly other compelling questions based on the criteria you shared.

For example do I need a pin to be within 6 yards of the edge to consider whether I should play for an angle?  If a green is well protected on the right hand side and wide open on the left, that alone would be enough for one to make a decision to come in from the left hand side and avoid carrying all the trouble on the approach. Ditto if that fairway only happened to be 28 yards wide instead of say 32.

The water or OB is the other head scratcher because there is nothing else on a course that makes me chase angles harder than playing to a best spot to avoid penalty strokes.

It seems to me from the tweet you posted in post 219 that the definition of better angle seems to rest solely on the player having the most green to play with, or as he puts it “For as long as the game has been played, people have been saying you should play for the better angle. The hole is cut on the right? You should try to hit it up the left-side. The advice is as old as the game itself. Is the advice accurate? Is it easier to score when you have the "better angle"?”


There is no mention of angle being created by orientation of the green or flanking hazards for instance. Take an old classic course like Sunningdale which has quite a few oblong or roughly rectangular greens that have flanking hazards and where the green is usually orientated to favour an approach from one side of the fairway ie. playing up the length of the green with no fronting hazard. If for example the green is orientated to the right side of the fairway but the hole is located on the right side of the green, then the Arcoss stats would have the better angle as being from the left even though you might have to play over a bunker. In that situation most if not all (average) golfers would probably think in that the better approach angle was from the right.


How much green there is to play with might be a consideration but in most of the classic courses I play over here it is usually a much lesser factor.

At the end of the day the "angles don't matter" Stagner/Broadie type of thought is based on large sample dynamic programming methodologies. A rough example of this:


Out of bounds = 2-strokes -


Decision - challenge the side of a fairway closer to the OOB in order to get a better angle into the green


>> Result = move your expected dispersion towards the side with the OB thus increasing the probability of going OOB to 20% instead of near zero (risk = expected strokes lost of -0.4) you would need to increase your probability of a getting one less (birdie) stroke by 40%. No angle is realistically incrementally improving your chances of birdie by 40%. 


If a fairway bunker is 3/4 of a stroke - then the angle would need to improve your chance of birdie by the increase of birdie percentage from the "correct angle" as opposed to the incorrect angle achieved by avoiding the bunker. I believe that the aggregate results being discussed herein are making the case that the increased birdie probability of chasing the correct angles just are not there compared to increasing the probability of incurring larger penalties associated with OOB, water, fairway bunkers and the like.


Are there cases where an angle can be worth an expected stroke value that is sufficiently? Ones I can think of are where you just can not hold the green from one of the alternatives due some combination of carry hazard, firmness, contrary slopes or the like.

Yes. It's wide for nearly everyone. The only truly accurate players (in general)… are the shorter ones, because the ball doesn't travel far enough to get too far offline. And they're often less "accurate" as measured by degrees offline than better players. As measured by fairways hit, well, that's why the LPGA Tour has players who are "more accurate" than on the PGA Tour.

We are talking about SCORING. Not the experience or the fun or thrill. I hope architects never care about my or anyone else’s score.
Yes. I can tell someone to play Tobacco Road in the most boring, strategically sound way… but if they want to go for the green on 11 with a 5I in their hands for the one-in-50 chance of pulling it off… cool. Good for them, and I hope they beat the odds, because they'll remember that shot for a long time. Or however long it takes them to get out of the bunker 30 feet deep and short, whichever comes first.  ;)

Let's dispense with the "one side of the tee box or the other." Yes, people will say they "feel" more comfortable over the shot, but there's no evidence to suggest that players actually score differently by changing the angle they have to a green by about a minute's worth on a clock.

I did some preliminary work on this once. Not enough to be statistically significant (I got to like 50 shots, while I'd want to have about 150+ personally), but there was basically no scoring difference. The angle isn't often big enough anyway. Yeah, people feel a bit better, but… it didn't result in anything. So until you have actual data here, you're just saying stuff that people "feel" like should be true without really knowing if it is or not.

Ira brought up the 11th at Augusta. There's water there. Would you care to take a stab at the results there? Go back to page 11 for the graphic. What are your guesses?

And there certainly wasn't any controls that factored in weather, fairway slopes, preferred shot shapes, particular weakness or strengths of ones game, etc.
Because those things come out in the wash. If a golfer fades the ball, and he "tends to miss right more than he misses left" as was said (IIRC)… then he's already giving shots away, because he should be looking to center his distribution pattern, and THAT would be his aiming point. If he consistently aims to fade it 5 yards and fades it between 3 and 25… then he's just being kinda dumb, no?

And the emphasis on scoring has been all one sided, about making a good score with par or better, and forgetting about mitigating risk in trying to avoid worse than bogey.
No no no. It's far closer to the opposite of what you've said than that. Proper strategy lowers scores not by having the 15-handicapper make more birdies and pars, but by making fewer bogeys and doubles. How? By saying "no, don't challenge that bunker. Aim about 30 yards away from it, or more, because there's no real trouble over there."

The water or OB is the other head scratcher because there is nothing else on a course that makes me chase angles harder than playing to a best spot to avoid penalty strokes.
Not sure what you mean here. Hitting away from OB isn't "chasing angles." You're just hitting away from a penalty — you're not hitting it so you have a good "angle" to the green or your layup on a par five or whatever.

Are there cases where an angle can be worth an expected stroke value that is sufficiently?
Yep, pretty much. That's how this strategy stuff works.

And as I've said, we can talk about generalities, but we advise players on things that fit them. Some have smaller dispersions with their drivers. Or some are really good with wedges. Some pull their wedges more often than they realize, so they need to actually shift their aim so that their distribution is centered over where it should be, etc.

Here's the thing that some have mentioned, too… but not enough: 95% of golfers (or more) aren't considering any of this stuff when they play golf. So to those of you trying to discard shots and data because it doesn't match whatever new criteria you set up (and by the way, Arccos does know wind direction/strength, temperature, etc. in the area at the time shots were hit)… have to realize that most of the data isn't being played by people "chasing angles" anyway. That doesn't make it any less valid; the opposite. If the left side of the fairway on a certain hole was actually the "better angle," then millions of golfers would unwillingly and unwittingly be scoring better from there. Who cares where they TRIED to hit it - the fact is they ended up hitting from what is supposed to be the "better angle." And yet no data supports that they actually score better from there.

When we consult with a player we often consult more with the caddies, because they're the ones who can help their players gain a shot or two over time, by knowing this stuff. The players often just want to understand the over-view, to understand that we know what we're talking about, and then most of them just put it on the caddie to tell them where to aim. So, we work with a LOT of caddies to actually understand and know this stuff. The caddies are the ones writing everything down, and choosing where a player aims, etc. It's on him to know the system, most often, and the player to hit the shot. It's also on them to know how to adjust strategies when you're no longer playing for the "lowest average score." i.e. late Friday when you're two outside the cut line, late Sunday when you have a chance for a top-ten finish (and the potential T6 outweighs potentially falling from 12th to 18th…), etc.

Here's where I land on this…
- I (and Lou, and Scott, and Mark) have shared data showing that angles don't often matter.
- The other side has shared anecdotes and tried to discount what the data shows, but doesn't have any of their own data.

I believe the latter is true largely because… there's not really data out there supporting "angles matter as often as y'all think." I've looked. I haven't seen it. And I didn't go into it with an assumption. Hell, the data about how far away from the flag golfers should aim from as little as 70 yards surprised the heck out of me back in 2013/2014.

That's much too long, and I don't blame anyone who doesn't want to read it. I'll leave y'all to this thread, for the most part, as I'm headed south to play a little golf.  :)

I hadn't realized that they added the walkway behind the green.  It kind of ruins the "purity" of the island green concept, but it is absolutely necessary to spread wear out from the original narrow walk on.  I would never do more than a peninsula green to maintain the wide of the walk up that is necessary to spread wear.  And, I always wondered why big time architects never seemed to worry about that.  My public clients would crucify me if I attempted something like that.  This confirms my long held suspicion/belief that if it can't be maintained easily, it will eventually be changed.


Ah...to bring it back to the topic.....angles do matter when you are considering circulation on and off a green........ ;)

If you look at the difference in what happened for a player who shot 88 one day and 94 the next, I can almost guarantee the story is found not in pars or birds, but how many doubles or worse did they take.
Agree 100%. My own game speaks to this. Doubles and triples are round killers. One per round or perhaps per side you can get away with, depending on the number of pars and birdies made to offset them.

Mike-It’s always rung true for me that if I can limit the doubles to one a side I’ve at least got a chance to shoot a decent score.

Could someone please speak as they might to a small child or a golden retriever and explain how the following individual factors may influence the impact a shot's angle of approach will have on a player's scoring potential for any given hole?

Ball Flight:
  • Decent Angle
  • Spin
  • Shot Shape
Ground Conditions At Shot Landing Site:
  • Firmness
  • Grass Height
  • Slope
  • Moisture
  • Hazard Proximity
Player Characteristics:
  • Consistency
  • Aggressiveness
If these factors have little to no influence, please explain why. If there are other factors that have greater influence, please elaborate on them as well.
I apologize for sounding like a broken record, but I'd like to press on this question once more.
If there is a preponderance of data that supports the hypothesis "angles don't matter" it would seem a requirement to validate said hypothesis would be the quantitative understanding of the individual factors related to play and their significance related to angles and scoring.

I've taken a stab and listed out the factors expected to have some level of significance on scoring and angles. Can anyone who has a greater understanding of the data collected speak to what factors are significant, and by how much? Or, speak to why these factors are not significant?

This piece by Joseph Lamanga appeared in today's The Fried Egg newsletter, discussing Brandel Chamblee's conclusion that angles don't matter very much.


                                                             WHAT'S BRANDEL'S ANGLE?
On Wednesday, No Laying Up released a podcast with Golf Channel and NBC analyst Brandel Chamblee. Throughout the conversation, Chamblee explains his position on distance, the irrelevance of angles, rough as a necessary ingredient to challenge the best golfers in the world, and more. While I agree with some of what Brandel had to say, I strongly disagree with a few of the most fundamental points he expressed on the podcast.

A little over 30 minutes in, Chamblee states that “if you give players the better angle into a hole location versus on the other side of the fairway where they have the worst angle, at every single distance, the worst angle, on average, scores better than the one with the best angle on tour.” I have no idea what data Brandel was fed to reach this conclusion, and I’m skeptical that he could explain how these calculations are derived, but his claim runs counter to any data I’ve ever seen or analyzed. Brandel should be pressed for more details on how he reached this conclusion.

I tried to roughly recreate the calculation Brandel references based on his description in the podcast. I pulled some shots, limiting the data set to second shots from fairway lies on par 4s longer than 400 yards. I defined a “Good Angle” as a shot from the right side of the fairway to a left pin or a shot from the left side of the fairway to a right pin, per Brandel’s wording. Here are the results:
The numbers show that there is neither advantage or disadvantage to having Brandel’s definition of an advantageous angle. I am highly skeptical of the data Brandel saw to conclude that players score worse from a better angle, and assertions like that should be scrutinized. Not all data-driven insights are correct, after all. The data-driven insights I provide should be challenged, too.
Nevertheless, the data I’ve provided seems to back up Brandel’s central claim that angles don’t matter. However, the above definition is a pretty imprecise way to classify angles. We should try to get more precise when possible. Fortunately, I have data from an analysis I did a couple of years ago that paints a better picture of the value of angles. For every shot, I calculated how many feet of green there were between the approach shot location and the flag on a direct line. Instead of simply considering a shot from the right side of the fairway to a left flag as a “good angle,” this analysis considers a shot with ample feet of green to work with as a “good angle.” I’d contend that this is a better (albeit more complicated) definition of a good angle.

The data showed that under this definition, there is virtually zero benefit to having a good angle from wedge distances in the fairway. This result makes sense, as professional golfers are consistently able to stop shots on the green immediately from the fairway with a short iron in hand. However, for shots with longer irons (180-250 yards), the data showed between a 0.10 and 0.15 stroke advantage in having ample green with which to work.

These results are intuitive: the more a golf ball bounces and rolls, the more having an advantageous angle matters. In professional golf, tour players hit the ball so high and with enough spin that angles rarely matter, a reality exacerbated by the ever-increasing distances at which players hit the golf ball resulting in shorter approach distances.

So do angles matter? Yes, just not very much. They’d matter more after a significant rollback, but even under those conditions, I agree with Brandel’s argument that golfers should not take on risk to hunt advantageous angles. Pursuing lines of charm at the risk of finding rough or a penalty hazard is not worth the marginal benefit of a good angle.

Thus, Brandel concludes, the best and only way to challenge a professional golfer is with thick rough. He goes on to ponder whether we want rough that produces a penalty of 0.3 strokes, or 0.4, or maybe even 0.6? The underlying assumption, one that Chris more or less affirms, is that the combination of fairway width and rough length are the only variables that dictate how much a golfer is rewarded for driving the ball accurately, which is just not the case. All elements of a golf course design must work in concert to produce a holistic test for professional golfers, as I wrote about earlier in the week in a free public post on how Muirfield Village rewards driving accuracy. For reference, finding the rough at Memorial is typically about a 0.45 stroke penalty, which isn’t solely due to the length of the rough, as outlined in that piece.

To understand how driving accuracy is tested, one must consider the entire design and strategy of a golf hole, not just look at the length of rough. When Brandel says within the podcast that this is a “setup conversation more than an architecture discussion,” he implicitly dismisses the importance of design, which is a crucial component in any test of top players. It also may explain why he continues to insist that we should all marvel at how straight Bryson DeChambeau drives the golf ball, an assertion that falls apart when you dig into which courses Bryson has succeeded on and which courses have given him trouble. Spoiler: he tends to do well on golf courses with thick rough and narrow fairways that fail to punish wide misses, because contrary to Chamblee’s claims, those golf courses don’t always equate to rewarding driving accuracy.

One last but important point: all of the data upon which Brandel Chamblee and I are basing our findings is PGA Tour data. The data comes from PGA Tour courses, many of which are soft, feature 33-yard wide fairways, and are played with wedges in hand. If every data point in the data set were with a five iron into firm greens on 80-yard wide fairways downwind, the value of angles might show up in the data a little bit differently.

I don’t disagree with everything Brandel said. In some ways, much of what I’ve argued within this piece isn’t that far off from many of his assertions. But the ways in which Brandel should be challenged have important implications. Thick rough is not the only way to test professional golfers. Often, in fact, thick rough fails to adequately test professional golfers (see Valhalla Golf Club). Meanwhile, some of the best tests in professional golf (see Augusta National) don’t rely on thick rough to test the skill and strategy of the best players in the world. Thick rough isn’t the only way to reward accuracy, but to fully embrace that, you’d need to put some effort into understanding golf course design.

Be careful going too far down that path, though. You might end up concluding that architecture matters, and that the game board upon which the sport is played would benefit from a rollback.

While I tend to agree that angles matter much less for the best players. I disagree that rough is the only way to challenge the best. First, I have no context for “challenge”. What does this mean for the best players? Second, how do we explain Pinehurst 2? Maybe it doesn’t meet the challenge criteria, but I think the best often falter at #2 and it’s not due to rough. The fairways are a bit wider than “traditional” US Open setups and the rough more forgiving.

Interesting post Stewart. One thing to contemplate I think is how target changes with the "good" vs "bad" angle. Let's suppose you have a hole cut four yards from the left side of the green and the green slopes down from the left side to the flag, but then is fairly flat at the hole. The ground is relatively firm, such that a wedge shot will roll out a little if it lands on a flat bit of green from the fairway. If you're on the left side of that fairway, your target might be 12 feet right of the flag. Let's suppose further that your shot pattern is about 20 yards wide at the distance you're hitting from (ten left and ten right). You'll miss a small handful of shots left of the green, some that land left edge will bounce towards the hole, most will end up between the hole and 25 feet right of it and a handful of shots will end up well to the right, but hopefully on the green.


Now take the same player, same distance, but from the right side of the green. He's got the better angle, so he aims only 3 feet right of the flag. A lot of his shots are going to end up closer than they would have with the wider target, but he's also now bringing the left miss into play. And those left misses are now downhill, short-sided, really tough to get up and down. The left misses offset the safer shots out to the right and it winds up being about a wash.


In short, the "better" angle makes people play more aggressively and lose a few shots as a result. If you play the same amount out to the right as you did from the worse side, then you haven't gained anything from having the better angle.


That's not to say that you can't come up with a situation where you're definitely better off playing from the "good" side than the "bad" side, but I'm guessing that those are few and far between and those get lost in Lou's 600 million shot dataset.

I think the thing the pros find the hardest to handle is distance from the hole. More so than rough or bunkers. Pinehurst 2 is very good at putting distance between the ball and the hole on less than perfect shots.

Not all data-driven insights are correct, after all...

So do angles matter? Yes, just not very much...

When Brandel says within the podcast that this is a “setup conversation more than an architecture discussion,” he implicitly dismisses the importance of design, which is a crucial component in any test of top players...

One last but important point: all of the data upon which Brandel Chamblee and I are basing our findings is PGA Tour data.

So, I think Joseph LaMagna, here, has touched on some really interesting points that I think I can help formalize a bit. Any purely data-collected theories are a form of empiricism. Chamblee is giving a post-hoc analysis of the data, which, all things equal, can be really helpful. However, golf does not exist in a state of natural evolution. It is a closed, designed system. Because of this, and this is where i get extremely heady, it is extremely sensitive to Soros's (yes that Soros) theory of market-reflexivity. Bear with me but here's a relevant paragraph from Soros's writing:

Quote
The concept of reflexivity needs a little more explication. It applies exclusively to situations that have thinking participants. The participants’ thinking serves two functions. One is to understand the world in which we live; I call this the cognitive function. The other is to change the situation to our advantage. I call this the participating or manipulative function. The two functions connect thinking and reality in opposite directions. In the cognitive function, reality is supposed to determine the participants’ views; the direction of causation is from the world to the mind. By contrast, in the manipulative function, the direction of causation is from the mind to the world, that is to say, the intentions of the participants have an effect on the world. When both functions operate at the same time they can interfere with each other.

FT Article (https://www.ft.com/content/0ca06172-bfe9-11de-aed2-00144feab49a) [PDF (https://www.opensocietyfoundations.org/uploads/9ae17912-2262-4646-8ffc-d01afc934c36/george-soros-general-theory-of-reflexivity-transcript.pdf)]

When we act from an empirical perspective, we see optimal strategies in the world only as we see it at the time. The players are taking their existing technology and applying it to the courses as they were, looking at past data and optimizing their strategies. However, course designers are architects are seeing these strategies, and are optimizing their courses themselves in reaction to these optimized strategies. When these two groups are acting at the same time, they interfere with each other's ability to collect and analyze data, because the paradigm is changing as they are observing it.

This is all to say that the data that Chamblee is using is backwards looking, and if courses are being actively changed (I'm sure many are not), the usefulness of that data inherently limited in it's ability create optimal strategies.

None of this is a "big point" as the changes that happen in a reflexive market are usually slow (especially one like professional golf), but because they are backward looking, when there is a paradigm shift, it is often undetected for some time because it will necessarily be a minority of the data until enough time passes for the new paradigm to appear in the data. Thus if architects are reacting to bomb and gouge era, slowly and then all at once, a new paradigm will emerge, and suddenly angles will matter again.

Brandel should be pressed for more details on how he reached this conclusion.
This is pretty well known, and I've posted the graphic before. Brandel misspoke a little - the scoring averages from the "good angle" are basically the same as they are from the "bad angle."

Which is what you then find when you run your test. I think he may have seen a few hundredths of a shot worse, which it often does show. I call that basically equivalent, he may call it "worse" because it technically is. What it doesn't show is any significant advantage to being on the good angle, and I think that was his main point.

However, for shots with longer irons (180-250 yards), the data showed between a 0.10 and 0.15 stroke advantage in having ample green with which to work.
If you run that at 175-200, on the PGA Tour, you again get the negligible difference. The "250" part of your test is doing a lot of heavy lifting there, as the ball is bouncing/rolling from those distances, even on the PGA Tour.

One last but important point: all of the data upon which Brandel Chamblee and I are basing our findings is PGA Tour data. The data comes from PGA Tour courses, many of which are soft, feature 33-yard wide fairways, and are played with wedges in hand. If every data point in the data set were with a five iron into firm greens on 80-yard wide fairways downwind, the value of angles might show up in the data a little bit differently.
If fairways are 80 yards wide, players could begin to aim slightly away from the center (assuming equal hazard difficulties on both sides). But, heck man, I play courses with some fairways that are 17 yards wide. Or 24. 33 often feels like a TON of space.

And of course if they played 80-yard wide fairways, angles could matter. That's part of why they almost never matter: being in the fairway is a huge plus over being in even light rough, and even rough is better than taking penalty strokes.

In short, the "better" angle makes people play more aggressively and lose a few shots as a result. If you play the same amount out to the right as you did from the worse side, then you haven't gained anything from having the better angle.
Correct. Except in situations where you can't control the ball landing and rolling out very well, the ideal target shifts very little from the "good" and "bad" angle.

The data showed that under this definition, there is virtually zero benefit to having a good angle from wedge distances in the fairway. This result makes sense, as professional golfers are consistently able to stop shots on the green immediately from the fairway with a short iron in hand.


So you are telling me that the angle of approach makes no difference on the 10th hole at Riviera?  Or the 16th at Pacific Dunes?


Why does everyone talk about them so much then?  Why do pros aim way left on 10 at Riviera, and why do they make bogeys when they miss to the right?


I will agree with you that on the average hole, the angle doesn't matter when you've got a wedge in your hands.  But it's just dumb to say that we can't make the angle matter.

It appears to me that the stats dudes want use a bit of correlation = causation and take aggregate data and apply to every situation. To his credit, Erik is saying that angles can matter greatly to lesser skilled players and those that can’t aerially attack greens from any angle. Aka, the MAJORITY of golfers.


But let’s be real real for a second. There’s a reason for all this angles don’t matter talk from people with data sets to support. It aligns with their *other* cause of the moment, being anti-rollback. Aka, distance is the only way to truly make a course more or less difficult.


If only there was a way have shots being played at lower trajectories and longer distances from greens.  :)

My answer would be that probably 5-10% of golfers would prefer to play a more challenging course, and that a rollback would provide that to them more easily than renovating hundreds or thousands of golf courses.


But then architects wouldn't get paid to tinker around and try to fight against the game becoming easier because of equipment!  And professional golfers are all on Titleist's payroll.*  So there are relatively few jurisdictions who are adamant about a rollback.


* I have always just loudly speculated that Titleist are far and away the biggest roadblock to a rollback, but it was nice to hear that speculation confirmed recently, by someone who has seen all the documents.

I think people are a bit up in arms because the technology is trickling down to local club matches. The majority of the near-scratch folks at my club now hit the ball 270-300, and that's pretty standard. I think the reason it's become an issue is that, with the bomb-and-gouge becoming the dominant strategy, the two groups (the 190-240 distances vs the 260-300) are effectively playing a different game.


I haven't had my equipment upgraded in over a decade or so, so I still have a neutral driver that I shape shots with. People playing at the high end of distances won't do that because their driver is dialed in to one single swing. It's just a different game at that point.

Tom, angles occasionally matter, and you've seen enough of my posts to know my thoughts on this, too, I think: when the ball is rolling, angles matter more.

The 10th is narrow (or shallow) with a lot of tilt. The ball rolls on it.

I will agree with you that on the average hole, the angle doesn't matter when you've got a wedge in your hands.  But it's just dumb to say that we can't make the angle matter.
Angles don't matter much when the game is point-to-point (minimal roll). If the ball isn't on the ground, it's not interacting with the architecture much.

Maybe not the majority, or the majority of rounds played. Even bad golfers can hit the ball in the air and stop it relatively quickly (they don't often play particularly firm setups).

Post by: Jeff_Brauer on June 07, 2024, 05:33:17 PM
10 at Riv also rolls away from the players, adding to its difficulty.  I've seen a few Tom Doak greens where they tilt away from the golfer, i.e., making the ball run out further for even high spin players. 


Imagine a green angled left, bunker front left.  Traditionalists would say coming in from the right is an advantage. I believe most gca's would raise the back right of the green, mostly to make it visible, but also to make a shot coming over the bunker at least possible with a backstop/upslope to help hold the ball.  And, in reality, if a green was impossible to approach from the "wrong side" by virtue of width (depth from that side) or reverse slope, then is it strategic by Ross' comment of "There is the hole, play it any way you please?"


It isn't the frontal hazard locations that affect top players, if coming over a bunker into a typical back to front sloping green, they will just hit it higher and with more spin to bring it back to the hole. 


The thing those Golden Age books didn't explore much was what happened when you did have the wrong angle?  The player can adjust his shot, aim for the fattest part of the green and walk away with 2 putts and a par.


The other thing wrong with the traditional golden age theories is that if you don't hit ground balls, it might be preferred (and I know many tour pros that say this) to come in from the side of the greenside bunker covering the green.  Like teeing up close to OB to give you the greatest safety angle, the approach shot can be aimed at the far side of the green with a hint of curve.  If perfectly aimed, it can get close to the pin without clearing the hazard and if it goes straight, you have downhill putt but don't find hazards.  The bunker comes into play only if you over cook the shot, which should lead to a penalty of some kind.

Jeff:


I remember at Archipalooza 23 years ago, Brian Silva saying that he would rather approach the 6th green at Pacific Dunes from the left, over the deep bunker, because he was more comfortable hitting his wedge the right carry distance, whereas if he came in lengthwise, he was always prone to pulling it over the left side and down the hill.  Most of the room thought he was nuts!


But then, a couple of years ago at the TPC at Sawgrass, some kid in a high school tournament played the 18th hole up the 9th [in the rough, no less] so that he could carry the ball back over the pond to that green, instead of taking the chance of pulling his second shot from the correct fairway!


I had Padraig Harrington say to me last year about a hole at The Renaissance Club, "I am never going to miss 8 yards short with an iron from 210 yards".  Those guys do play a very different game!  Indeed, a lot of the reason it's hard to design anything counter to them is because they never have to worry about a ball that's a bit dead, so their carry yardages are absolutely dialed in.  If a Tour pro's carry distance with the driver is 296 yards, he will confidently go for it if the carry is 288 or even 290 -- that's how consistent their swings are, and their equipment.  That would have been crazy 30 years ago.


That's why I think angles still matter -- because I hear the players trying to avoid them, and reduce every hole to carry distance, where they are much more consistent.

Title: Re: “Angles Don’t Matter”
Post by: Jeff_Brauer on June 08, 2024, 12:53:46 PM
Tom,


The thing is, in the older generation of pros I worked with, any time I said the goal is to challenge the hazard, I can't recall any saying they did that.  Haven't heard if from top ams, or mid ams, or even and especially low skill ams.


I also think the Golden Age axioms are too superficial as if someone coming in over a bunker will only have the option to fire at the pin.  Stats show that IF a decent player (although Lou's data also includes 5, 10, and 15 handicaps) comes from the wrong angle, he adapts by playing a conservative shot well over the hazard in front.  Not to mention, picking your line, distance, and shot pattern, spin, etc. is still a strategy. (Some would call it tactics instead, but I disagree, as you are still picking a spot to land, just like on the tee shot.


And, statistically, like most sports, playing defense wins championships.  A long downhill approach shot is harder than an uphill putt, but you probably still walk away with par, which is rarely a bad score.  As I have heard Jack and others say, avoid the bogeys because then you need two birdies to get under par.


Very shallow greens like Riv 10 at 45 degrees to the LOP make it harder to come in from the wrong angle, so yes, in those cases, and when the green falls away from one angle, the angle can matter.  How often should that happen in a design, where the green is narrower than the dispersion pattern?  Yes, it can make great players make bogey, but also makes life miserable for the everyday player.


Perhaps oddly, for players with great distance control, coming into a green over a hazard might make the shot easier, since wedge dispersion patterns are usually wider than long.  Thus, if someone knows their carry distance, and the exact carry distance of the line they take, they are probably less likely to miss the green.



As your Brian Silva example also shows, there is no way designers can ever imagine every mental process of every golfer, i.e., how on earth would we know how a guy who is prone to a pull with short irons would play it that way?  Again, play it any way you please.

I hit the driver 200 to 230 with a slight push or fade (ideally).  I create my own angle by teeing the ball near the right hand marker and aim at the left edge of the fairway around 250 yards out. 


Angles are critical for mid handicappers.  And fun to boot.

But it sounds as if the angle you're describing is the same no matter what the supposed strategy of the hole calls for. I think playing one shot over and over again because it's the one shot shape you hit is not the same notion as playing an angle for a strategy based on the particular design of a golf hole.
Title: Re: “Angles Don’t Matter”
Post by: Jeff_Brauer on June 08, 2024, 03:04:22 PM
The same stats that conclude angles don't matter also show that players who stick with a standard shot pattern have tighter dispersion patterns than those who switch shots to play the shot the hole calls for.  I guess we would call that a top level strategy, as opposed to a hole based strategy.

This is it.


The premise of this thread - as if it needs to be said again - is not absolute.


It is a flippant title that “angles don’t matter” only in terms of setting up approach shots; and that they matter a lot less than architecture strategy would have us believe.

A podcast with Edoardo Molinari: https://overcast.fm/+-SYyhIbZ4 (https://overcast.fm/+-SYyhIbZ4)

39:30 mark… A quote: "On 99% of courses and golf holes, angles don't matter at all." Another: "The only course I can think of where the angle matters a little bit is the Old Course at St. Andrews, but there you have like 90 yard wide fairways" (and firm greens, which he mentioned in the sentence before - i.e. the ball rolls out and doesn't stop pretty quickly).

In short, he re-states the same things I've been saying… because those of us who rely on more than anecdata and old beliefs, and instead rely on millions of shots and holes of data are in agreement.

And angles can matter to an individual shot (talking scoring only here), but if it truly is easier from the left side of the fairway on this one particular hole, you just aim at the middle or the right-center where you should, and then are mildly grateful when you pull one to the left side of your normal Shot Zone (dispersion pattern) and end up on the left side of the fairway.

P.S. My talk almost exactly a year ago at the ASGCA's annual meeting gave a bunch of situations and reasons why angles did matter, but most didn't deal with scoring. There were esthetic reasons. Drainage reasons. Etc. If you're talking about scoring, angles — and the chasing of them — "don't matter at all" in the words of Edoardo.

I still don't agree with his/Molinari's contention but suspect the difference is more in the context.


I suspect both Erik and Molinari are thinking of elite level golfers playing courses that are less than fast and firm while from my perspective, that of an undoubtedly average golfer playing on courses that are usually a good bit firmer than they are looking at, their contention simply doesn't hold water.

I appreciate your perspective.  While I begrudgingly acknowledge he occasionally makes reasonable points, I don't care to engage him on that level (or at all, really).  The manner in which he consistently behaves on this board is simply obnoxious.  Perhaps this thread or post wasn't the most apt moment to (rudely) engage him, but it is where I chose to do so.  Like so many others, I spend a lot of time reading this board, new topics and old, and he consistently clutters the board with combative text, so much so that I long ago stopped considering his perspective on anything.  Yes, I should ignore him.  Yes, I can block him (or so I am told).  He is a net negative contributor to this board, and I don't appreciate it.  Thanks.

]Brian, I can agree with you there, also based on my experience in discussing architecture with architects.  It appears that very few have the personality type to delve into statistics and the like.


I still think they matter, and that the millions of shots tracked by Lou and others probably covers at least the results of the golfer's indecision and mindsets, so it IS factored in. And, like medicine or other fields, the long term trend is more scientific and less art, although most of us love the illusion of the romantic artiste.  Personally, I wouldn't go to a doctor who still believed in bloodletting and I would trust a golf pro (or architect) who uses all the stats available today to assist in strategy decisions.

No golf design idea is so good that it should be used repeatedly on all 18 holes, including statistics.  Or, said another way, the sucker punch hole is probably the one that golfers will ignore the stats on and take a chance on if appropriately designed for that situation.

Many of us architects have also been accused of using this as their marketing platform, but for the most part, none of us trumpets their own work, but prefer the actual content of open discussions of different ideas.  And, it seems clear to me (although this is probably better on the "Social Media" thread, I dare say it has changed architecture, which is something I think the Fried Egg and others is reporting on, but didn't do themselves.

Hear hear. Big Data Golf dumbs down the game in certain ways because it implies that golfers should play against their instincts even in what they know to be potentially high-stress, high-leverage and high-downside situations. Every single golf shot contains so many variables that could lead to going against the data that stripping the individual golfer of his or her agency can be destructive. The data is by no means useless, but it's nowhere near all-knowing.


The "Angles Don't Matter" narrative is starting to become extremely exhausting at this point because it relies on the made-up straw-man concept of "chasing angles." Aiming down the right half of a fairway isn't "chasing an angle" so much as it's an attempt to adjust the spray-pattern of shots in such a way that the golfer, with self-knowledge and agency, knows is going to benefit him or her.

Of course, I agree it is all in the hands of the user.  That said, proponents of the system say that you need to be disciplined and NEVER allow your instinct to override the stats, except perhaps when an all or nothing situation in your match makes you.  Even Erik says this.

Listening to Jeff Warne’s radio show from this past Sunday he had the developer and the Co- Arch of a new course in the Aiken area on. They talked quite a bit about designing the course so that you needed to play angles.

You really are your own biggest fan, aren't you.  Honestly, it's pretty obnoxious.
I think comments like that right there are pretty obnoxious. But I like to stick to the topic, so… I'll do that now.

I suspect both Erik and Molinari are thinking of elite level golfers playing courses that are less than fast and firm while from my perspective, that of an undoubtedly average golfer playing on courses that are usually a good bit firmer than they are looking at, their contention simply doesn't hold water.
The PGA Tour typically plays firmer course setups (particularly at the greens) than the average golfer faces. The data from hundreds of millions of shots doesn't align with what you're saying here.

I don't care to engage him on that level (or at all, really).
And yet…

The manner in which he consistently behaves on this board is simply obnoxious.
Says the guy doing the name-calling. ;)

In the interest of addressing the actual topic of this thread, I will say that the aspect of golf performance that the data-driven experts seem to ignore (or at least not consider enough) is psychology. For logical players, conclusive data should instill confidence and lead to improved performance. In many cases, it does. However, for many of us, something changes when we step over the ball. For some, thoughts race, countless swing thoughts shuffle through their brain. For others, the mind goes blank, causing a momentary loss of any semblance of how to hit the pending shot. As a mid-handicap player for 30+ years, I have proven many times over that I am capable of hitting the necessary shots to score well, but doing so consistently evades me. I work with heavy data and analytics all day every day, so I understand and endorse its potential power, but for that to translate to performance requires effective, flexible instruction as well as a receptive, capable audience. Banging people over the head with data rarely works.  I can speak from extensive experience.
I don't see how that really addresses the topic at all.

Some here would tell you to aim for the left-center of the fairway and to challenge the bunker to give yourself the best angle to the green, data would tell you to aim away from the bunker a bit, toward a spot just in the right-center of the fairway perhaps.

Either way, you're just talking about a point to aim at. That's all this is. Psychologically, a player is often more comfortable not aiming close to trouble, and can take comfort in knowing the data says they're making a smarter play.

And the word "consistency" is perhaps the most over-used word said by golfers taking lessons. Literally everyone wants more consistency; it's a given. If you could hit your 7I 150 yards and into a circle 10 feet in diameter (and all of your other clubs comparatively accurately), you'd win every PGA Tour event ever played, despite a (relative) lack of length. You're a mid-handicapper because you're as (in)consistent as you are. Your swing produces a wider variance of shots than a golfer with a lower handicap, in general. You hit some good shots, you hit some bad shots. So do pros… it's just that their bad shots are WAY better than yours, and their good shots are all generally a little bit better, too. Their distribution is a lot narrower.


Nearly everyone playing golf for awhile hits an occasional "pro-level" shot. It doesn't "prove" what you may think it proves; yes, you're capable of it, but it's an exception when you hit it, and it's closer to the rule when a Tour player hits it. It's like saying you won $200 on a scratch-off ticket once and saying "you've proven you're capable of winning money playing the lottery." It doesn't hold up over the long term at your ability level.

Guys-What you have to remember about Erik is that he participates on GCA in an effort to sell you something namely his data driven “Lowest Score Wins” system and not to participate in the frank discussion of golf course architecture.
Yeah, that's not remotely true. If it was, I'd be earning, I don't know, two cents an hour, tops? What you just said is not accurate in the least. But I sense that it's a convenient way for you to ignore some things you don't like.

Hear hear. Big Data Golf dumbs down the game in certain ways because it implies that golfers should play against their instincts even in what they know to be potentially high-stress, high-leverage and high-downside situations. Every single golf shot contains so many variables that could lead to going against the data that stripping the individual golfer of his or her agency can be destructive. The data is by no means useless, but it's nowhere near all-knowing.
Understanding the data is but one factor in a player's decision on where to aim, what type of shot to hit, etc. The players we work with learn these kinds of things. They learn when to perhaps be a bit more aggressive or a bit less. They learn to understand normal variance, and manage expectations. If you think it's a purely formulaic endeavor, without consideration for the player and the situation… you don't really understand what we do.

But, in general, as Edoardo said… angles don't matter. Chasing them is often folly. He said on 99% of golf holes or courses, and I would not go quite that high… but he's also mostly talking about PGA Tour players.

The "Angles Don't Matter" narrative is starting to become extremely exhausting at this point because it relies on the made-up straw-man concept of "chasing angles." Aiming down the right half of a fairway isn't "chasing an angle" so much as it's an attempt to adjust the spray-pattern of shots in such a way that the golfer, with self-knowledge and agency, knows is going to benefit him or her.
Oh boy, no. There are a ton of examples where golfers are encouraged to chase an angle "for a better angle on their approach shot" or whatever. They're not hard to find. They're almost always going to lead to a higher scoring average than not chasing the angle.

"Chasing angles" is not a straw man. Y'all are on a roll with your easy ways to try to ignore something that's inconvenient to your views.

Of course, I agree it is all in the hands of the user.  That said, proponents of the system say that you need to be disciplined and NEVER allow your instinct to override the stats, except perhaps when an all or nothing situation in your match makes you.  Even Erik says this.
Yep. If you're driving it really well on a given day, you can narrow up your Shot Zone (or poorly, then that may require an adjustment). Or if a wedge shot really suits your eye, we help players understand how they might shift from taking the "straight data" approach in a situation like that.

If you're two outside the cut line with five holes to go, we teach our players how to maximize their chances of making the cut — what are the best opportunities to make birdie in the next five holes (and if they get down to three holes… how to further shift the GamePlan…).

Like I said up above, it's not "100% always follow the data." It is when we're talking generalities, because we can't know the exact situation or the player playing. So it leads to things like Edoardo saying "99% of the holes, angles don't matter." Generalities. There's no other way to have a conversation, reasonably, unfortunately. Unless you get a BUNCH of specifics, and even then, it's just about that ONE thing. That one situation or shot. Change one of the many variables there, and it might change the best option.

If the Angles Don't Matter moniker bothers you, how about "Avoid the hazards first and foremost" as a substitute?
Yup. (Generally…) Penalties are shots lost. Bunkers are worse than the rough, and they're both worse than being in the fairway from the "wrong" side.

It's really not a complicated thing, but neither is "NBA players should take the easy layups or shoot threes. The mid-range jump shot is inefficient." (I'm not a basketball fan, but I think that's at least a half decent summary of the shift in how the game is played these days?) Is that ALWAYS the case? No. But in general, the game of basketball is played differently now. So are MLB games. So are soccer games. So are football games - look at how many teams go for it on fourth down these days. Look at how many teams choose when to go for 2. Etc.

If angles don't matter, does it also mean we stop building them?
No, I gave a bunch of reasons or times when angles matter at the end of my presentation last year.

Just noticed this.  As an octogenarian high handicapper, I say that angles matter a lot.
I've always said that they begin to matter when the ball is rolling. You probably aren't flying it and stopping it relatively quickly, so yes, they likely matter more to you than me.

They hit the ball there, apparently for a reason...all of them.  Is it the best percentage location for the next shot? Is it the best angle for the next shot?  Did someone (course set up guy, course designer???) dictate that location as the best place to hit your ball?

Random thought over the weekend.....for those who are angered by the phrase "angles don't matter" even though it is statistically proven, how about "Statistically, going for the pin isn't a wise play?"  That is basically the context, i.e., no matter where you are in the fw, even with what you deem a more favorable angle, shot dispersion patterns now tell us it is a low % play to aim close to the edge of a green with a tucked pin....which has long been told to us ams as the best way to play a hole. 


Basically, low handicap players need to get within 8-10 feet to have a statistical 50% chance making a birdie putt but only get within 10-12% of the approach distance to the cup.  At 160 yards, that is 48-54 feet from the cup, almost 5-7X more likely.  Over time, the bogeys simply outweigh the birdies (I think we can all get behind that observation) no matter where you approach from.


Ditto for "challenging a fw bunker." Birdie out of the fw hazard drops to near zero, I would think, whereas bogey from a hazard chances go way, way up.  If your dispersion pattern is 10-12% off the tee for, say 280 yards, that is 28-34 yards.  And, despite many last generation pros believing it, there is no way you can "take one side out of play."  No matter where you aim, it is still 28-34 yards, total, with misses on both sides.  If you aim within 28 yards of that fw bunker, you take a chance on getting in it. 


Again, that is over time.  You can occasionally make a birdie by playing the angle at a crucial point in the match, but you should never expect it.

I get that, but it's also sort of like the old argument we'd have on here about whether only good players can take advantage of strategy (especially angles). I disagree, but I also believe that the statistics might show that angles don't matter in part because there isn't much strategy built into most courses (and it's pretty weak when it is included).


The course I grew up on had very little difference in approach difficulty from any given location as long as the distances were equal (i.e. left rough at 150 yards vs right rough at 150 yards being equally difficult). And the majority of the type of courses I've played in my life have been similar to that. But the relatively small number of times that I encounter real strategy (challenge the hazard to have an easier subsequent shot) it's been refreshing, even when I can't quite execute.

It's a good post, Jeff. Dispersion off the tee is normally bigger than the 10-12%, too. I don't necessarily go with Scott's 60-65 yards, but even at 40 yards, or 45… the math shifts even more in favor of the tiny or more-often-than-many-here-would-believe non-existent reward not being worth the often substantial risk.

I also believe that the statistics might show that angles don't matter in part because there isn't much strategy built into most courses (and it's pretty weak when it is included).
That doesn't bear out. Over the years I've been sharing what the data shows, I've asked for people to give me examples. I think I may have given more examples of holes where it can matter (the first at Royal Melbourne in the Presidents Cup) than others.
But the relatively small number of times that I encounter real strategy (challenge the hazard to have an easier subsequent shot) it's been refreshing, even when I can't quite execute.
This is often demonstrated to be wrong for two reasons:

First, the benefit is often not nearly as large as people perceive. I've shared the charts from PGA Tour players showing their play from the "better" side of the fairway to a tucked pin, and the scoring is almost exactly the same as they do from the bad side and the center of the fairway. The data is consistent with even 10 handicappers, too. The fairway — anywhere in the fairway — is almost always about the same, and better than anywhere in the rough (comparing the same distances, that is).

Second, nobody's even really saying the first thing, because sometimes there is an advantage to being over there. The problem is, by aiming for that side, you're bringing more trouble into play. Let's say it's just a fairway with rough: you're better off aiming for the middle, and accepting your fortune when your ball finds the "better" left side over the "worse" right side. But even on that hole, if you aim for the left side, you're going to end up in the rough more often, and the rough from the "better" side is still often worse than the fairway from the "worse" side. The risk is often not worth the reward.

Angles matter… visually. Artistically. But, in terms of scoring, angles matter very seldom, and almost exclusively when the ball is rolling. This requires either firm conditions, lower ball speed players, recovery shots from bad places, extreme width, or a combo of two or more. A rolling ball interacts with the architecture.

Hitting for the centre of greens is uncommon these days. It is said to be throwing money away and no way to win. Doing the opposite is one certain way to miss cuts and throw tournaments away.

We've learned a bit since then, Mike. But it sounds like he was close.

(FWIW we rarely advise people to aim at the middle of the green with a wedge. But we rarely advise people to aim right at the hole, either, depending on where it is.)

This is what's changed from the 1950s and 60s when he was at his best.


5. Anything else?
The main thing about golf is to get your first shot onto what used to be called fair ground, now called fairway. It does not matter a lot if you are 50 metres on or 50 metres back. That will be taken care of by the next shot. Getting the ball into play – or as I call it, serving the ball into court – is vital. I first came upon this when I played the US Open in the early 50s. In those days, the US PGA made fairways we thought were ridiculously small. They were only 20 metres wide and all the players complained. It was so very different to every other tournament we played, but it became widespread. In any championship worth its salt, the targets were pretty small.

Erik,


My mistake. I had been working with the USGA Slope guide, where they measured the 2/3 probability of hitting a target, where as users of the stat system measure 99% probability in width, equating to 60-64 yards at 300, or 20+%, plus or minus.


I wonder what the stats tell us when going from a 66% chance to a 99% chance of hitting a target doubles the required target width?

For many years I kept my handicap at an MGA club. 

The MGA has a terrific monthly (or 6 times per year?) magazine.

Once a year they list the course record at every club in the section. 

As a part of this, every page or two they'd have a quarter-page box highlighting the details of said course record.

I can't remember the course, or the name of the guy who posted the record score...

...but it was (i) a private club, (ii) the round was recorded on a Monday when the club was closed, (iii) the assistant pro posted 61, and (iv) the score is notable because there were no flagsticks in the holes.

Make of it what you will.

I caddie regularly for a number of very very good players and that story always resonates with every one of them.

Hi Jeff - I think you're mixing up two different measures. 10% error rate is 10% either side of the target. An error of 28-34 yards is the same thing as hitting into a space 56-68 yards wide, which is pretty close to the 60-65 yard window. If you actually mean hit it into a 10% wide window, then the approach shot error should be 5% either side, which is more like 24-27 feet either side of the target in your example. 5-7% error is I think what you'd call a "good shot" on tour. It's a little hard to tell because their pin positions are so often cut so close to the edge of the green that they're not aiming at the pin. That means you have to guess where they were aiming to figure out how much spread they had and they won't all have the same target.


Fawcett does have some pictures floating around of an island green par 3 where the pin was right in the middle of the green. I think it was about 180 yards and the shot pattern covers the entire green with some in the water. Those ones in the water are clearly (by tour standards) poor shots, but even excluding the obvious outliers, the scatter is surprisingly big.


65 yards wide at 300 yards for PGA Tour players is roughly 95%, not 99%. They will on average miss that window around 2-3 times in a 72 hole event. The idea is that when those shots happen, you take your medicine. Avoiding that ever happening would be too conservative and you'd give up too much in approach shot differences on the other 50-55 shots

Michael,


The % I am referring to is the entire width of the dispersion zone, not the % of times you might miss.  But you are correct in that if I deem my tee shot width dispersion as 64 yards, I will aim 32 yards away from a hazard in the LZ.


I will also agree that a player using this system might not use their entire dispersion pattern as a guide, i.e., some might use 95% vs a near absolute certainty of 99% in picking their own level of "outlier" shots.  99% is probably not used all that often.

I also believe that the statistics might show that angles don't matter in part because there isn't much strategy built into most courses (and it's pretty weak when it is included).

That doesn't bear out. Over the years I've been sharing what the data shows, I've asked for people to give me examples. I think I may have given more examples of holes where it can matter (the first at Royal Melbourne in the Presidents Cup) than others.

This is where I have some trouble with the data as described. And please bear with me here, because this is hard to put into words. I feel like we're talking about two very different datasets here and that there are multiple possible interpretations.

The first one, and what I was referring to above is that larger dataset of large numbers of golfers playing many different golf courses that is often referred to as "millions of shots". This is that vast dataset you refer to. I accept these numbers and your general interpretation of them, with the caveat that most golf courses don't feature a lot of strategy at all, so, to me, of course it will show that angles don't matter (very much).

Now your rejoinder to that was that even on what most would consider a highly strategic hole like the first at RMGC Composite, there is no statistical advantage to angles shown in play in the Presidents Cup. Again, I believe your statistics are accurate and believe your interpretation to be accurate. But my issue is the population of golfers represented in the data. These are the most elite golfers imaginable. Nothing like average golfers on average courses that represent the vast majority of the millions of shots referenced above. In other words, it's not quite an apples to apples comparison to me. (In still other words, for the elite players, yes angles don't matter in most cases)

So, what would be most convincing to me is if we could be shown the statistics of the millions of shots of the whole spectrum of golfers only on holes that are clearly built to the strategic style. I don't know if that has been done yet or if it can be done yet. I realize someone would need to decide what holes are truly strategic, I'd trust any of the architects on this board to make that determination.

Whatever such data would show, I understand that angles matter somewhat less than I used to think they did, and I'm using that knowledge to play more consistent golf now by being more cautious, suffering fewer penalty strokes and making fewer dumb mistakes and shooting similar scores to what I did when I was a better player. And yet, because I'm a low-ball, low-spin player (rolling ball) at this point in my life, even on the low caliber of courses I tend to play, I come across one or two shots a round that could really be considered strategic and I greatly enjoy playing them, even when I'm not really able to always take advantage, which is what I referring to in the item below.



But the relatively small number of times that I encounter real strategy (challenge the hazard to have an easier subsequent shot) it's been refreshing, even when I can't quite execute.

This is often demonstrated to be wrong for two reasons:

First, the benefit is often not nearly as large as people perceive. I've shared the charts from PGA Tour players showing their play from the "better" side of the fairway to a tucked pin, and the scoring is almost exactly the same as they do from the bad side and the center of the fairway. The data is consistent with even 10 handicappers, too. The fairway — anywhere in the fairway — is almost always about the same, and better than anywhere in the rough (comparing the same distances, that is).

Second, nobody's even really saying the first thing, because sometimes there is an advantage to being over there. The problem is, by aiming for that side, you're bringing more trouble into play. Let's say it's just a fairway with rough: you're better off aiming for the middle, and accepting your fortune when your ball finds the "better" left side over the "worse" right side. But even on that hole, if you aim for the left side, you're going to end up in the rough more often, and the rough from the "better" side is still often worse than the fairway from the "worse" side. The risk is often not worth the reward.

Angles matter… visually. Artistically. But, in terms of scoring, angles matter very seldom, and almost exclusively when the ball is rolling. This requires either firm conditions, lower ball speed players, recovery shots from bad places, extreme width, or a combo of two or more. A rolling ball interacts with the architecture.

Charlie, I had nearly the identical thought today, thank you for taking the time to write it out more currently then I would have.


I would love to see this for a course like Pacific Dunes. On #6, I'd have to imagine that a tee shot played down the right side of the fairway would yield a significant advantage over a shot down the left. That hole is probably a true outlier and an extreme example of angles actually mattering.


I'd be even more curious to see results for holes 2, 3, 4, 9 (upper green), 12, 15, 16, where I perceive there to be a distinct "better angle" from one side of the fairway, in the traditional sense. I'm guessing that some but not all of these holes would show an advantage for one side of the fairway that might be worth at least shading towards when aiming off the tee. Probably not worth aiming closer to the cliff on 4, but might be worth aiming down the right side on 9 to an upper green.


I think links golf and lower trajectory hitters make it much more likely that angles matter, at least on a few holes in a round.

Charlie, Ally, and Ian,


100% spot on, particularly the point that lumping all courses together is both a quantitative and logical error. Erik inevitably will tell us that angles do matter for shots on the ground, certain wind conditions, and the like. In other words, the exceptions swallow the rule, but the rule is the rule because the data is the data, except when it is not.

Thanks Ira, although I don't think anything I am saying is refuting Erik's points. That said, I haven't read all 15 pages of this thread...

I believe Erik acknowledges that angles very rarely do matter in high-level golf. And that they matter more, although still very little, the more the ball runs (due to turf or type of golfer). I am just hoping there is more specific real-world data to help us figure out where that line is for the average-ish golfer. Presumably Arccos and others have a few thousand rounds on a course like Pacific Dunes (or pick another course with lots of strategic interest).

From our friend Peter Pallotta:


Set aside for a moment the question of whether there are strokes to be gained by *intentionally* aiming for one side of a fairway over another.
The question remains: is there any advantage to be had, on occasion, from *accidentally* finding oneself on one side of the fairway instead of the other?
Well, to that point: since for most of us, dispersion is a reality both in terms of left-to-right misses as well us short-to-long misses, I would much rather be approaching a green from the angle at which it opens up to me rather than from the one the forces me to fly my approach shot over a bunker or pond.
In the first case, if (as is a common occurrence) I hit it slightly fat or misjudge the strength of the wind against or the degree of elevation change, I will end up short -- but still on or near the front of the green, and so a two putt par is still possible; while in the second case, that same (common) mishit or miscalculation will mean I land in the bunker or the pond, which makes a bogey quite likely.
Which means that, for me, an average golfer, angles *do* matter, and can lead to me shooting lower scores, even if I got to the better approach angle *accidentally*.
But, and this is the essence of it all: IF those ideal approach angles that matter and that can lower my scores are accessed accidentally, then they also must matter and serve as potential stroke savers if accessed intentionally.
That is: the green contours and green-side hazards don't change one tiny bit, nor care one iota in any way whatsoever, whether I am hitting my approach shot from a helpful angle on purpose-and-through-skill, or merely by happenstance-and-a-lucky-break.The golf course design does not judge my character or choices; it only embraces or rejects the shots I actually hit. 
Whether one particular golfer should, in any specific instance, actually try to get his tee ball to one side of the fairway instead of another is a totally different question. I can always look at a golf hole from the tee and *hope* that I will find my tee ball having come to rest at an ideal angle of approach.

"I have some regrets and made some mistakes when I first started. I started out hot with a PGA Championship and a Players title but a veteran player I respected told me I didn't know how to play for money. I asked him what he meant and he said I didn't know how to play percentage golf and earn good checks when you didn't win




"How did that affect you?"


"I took my foot off the accelerator on the course and put my foot on the brake and stated to play percentage golf, which I regret. As a result I shot a lot less scores in the 80s but nobody really cares about that. I didn't win as much."

I miss Peter’s contributions here.


But this thread has always just been about the second shot. The reference to the drive is that it’s not worth chasing the better angle for the second shot. It doesn’t matter if you end up in the “correct” spot by skill or by luck, as Peter correctly states.


Angles just matter less than we think for the second shot (they can matter).


I would even argue that the pre-occupation with angles for the approach shot has - counterintuitively - led architects to produce any number of boring course layouts chasing strategy 101. I.e. repeatedly using “bunker inside dogleg, bunker outside angled green” on par-4 holes…. Of course, it’s all in the execution but a lot of true strategy comes about by chance or by extreme cases.


All of the above doesn’t mean architects should stop building angled strategy in to their approach shots, just that they shouldn’t be a slave to simple notions of it. Also, just because angles actually matter less than we think for scoring, I suspect we reach that scoring average in different ways (hard angle plays more conservative, easy angle plays more aggressively, sometimes winning, sometimes losing but averaging the same). I know for sure that at Portmarnock, it still matters mentally to me where I come in from, even if I realise I’m probably over-emphasising the effect.

Of course angles matter especially on any well designed golf course from the time one tees off until they hole their putt.


We have all seen golfers (or done so ourselves) tee off from one side of the teeing area vs another!  We have all seen golfers (or done so ourselves) short side our approach shot to where getting up and down is extremely difficult.  We have all seen golfers (or done so ourselves) left ourselves with a putt on the wrong side of the hole or on the wrong side of a particular green contour that makes the putt far more challenging.


Angles matter and all good courses are designed with them in mind from tee to green surface.

My mistake. I had been working with the USGA Slope guide, where they measured the 2/3 probability of hitting a target, where as users of the stat system measure 99% probability in width, equating to 60-64 yards at 300, or 20+%, plus or minus.
Not a mistake, just a different way of looking at it. For scoring purposes, we have to consider closer to 90%+ of the shots hit, not only about 2/3, particularly when the outer 1/3 result in many more strokes.

Now your rejoinder to that was that even on what most would consider a highly strategic hole like the first at RMGC Composite, there is no statistical advantage to angles shown in play in the Presidents Cup.
I have, several times, called out the first hole at RMGC in the Presidents Cup as an example of a rare time when the angle did matter.


These are the most elite golfers imaginable. Nothing like average golfers on average courses that represent the vast majority of the millions of shots referenced above.
The problem with that is that the data is consistent from 15 handicappers to Tour players. Angles often matter LESS to Tour players as they're more point-to-point than even the 15s.

So, what would be most convincing to me is if we could be shown the statistics of the millions of shots of the whole spectrum of golfers only on holes that are clearly built to the strategic style.
We have that kind of data. And on several occasions, I'm given examples… like the ninth at Pine Needles one time. And each time, they fail to show anywhere near as much strategy as people think.


And yet, because I'm a low-ball, low-spin player (rolling ball) at this point in my life, even on the low caliber of courses I tend to play, I come across one or two shots a round that could really be considered strategic and I greatly enjoy playing them, even when I'm not really able to always take advantage, which is what I referring to in the item below.
I've always said that the angles don't matter… unless the ball is rolling. It's still largely a generalization, but it's a VERY wide, deep generalization.

I would love to see this for a course like Pacific Dunes. On #6, I'd have to imagine that a tee shot played down the right side of the fairway would yield a significant advantage over a shot down the left. That hole is probably a true outlier and an extreme example of angles actually mattering.
Nobody's said that angles NEVER matter. Edoardo in fact pointed out that you need a LOT of width and firmer conditions for them to matter. The 6th at Pacific Dunes may be one of the exceptions.

100% spot on, particularly the point that lumping all courses together is both a quantitative and logical error.
No, as I can look at thousands of times players play one specific hole.

Erik inevitably will tell us that angles do matter for shots on the ground, certain wind conditions, and the like. In other words, the exceptions swallow the rule, but the rule is the rule because the data is the data, except when it is not.
No, the exceptions remain rare.

Correct.

The question remains: is there any advantage to be had, on occasion, from *accidentally* finding oneself on one side of the fairway instead of the other?
I disagree that it's a good question.

Dustin Johnson was once asked why he decided to go after a tucked flag on the 17th (71st) hole of an event. He stuffed it to two feet and tapped in for birdie, winning by two eventually.

His answer: "I pulled it." He wasn't aiming there. He stuffed it "accidentally."

Two bits to this:
If there is a hole where there's a benefit, just delight in the times your dispersion played at the "proper" place puts a ball just beside the penalty area or bunker leaving a great angle that'll gain you a fraction of a shot.

But it's not something you can plan to do often. It's an accident. An outlier. Toward the fringe of your dispersion.

Which means that, for me, an average golfer, angles *do* matter, and can lead to me shooting lower scores, even if I got to the better approach angle *accidentally*.
Yeah, the thing is… the data doesn't really support this. At all.

If your shot pattern with a 7I is as wide and deep as you say it is, the bunker you don't always carry is irrelevant - if it's short right and you're in the left side of the fairway, you're still gonna come up short right pretty often. It may be a slightly better angle for the second shot, but again… you still don't aim at the left side of the fairway.

I've never denied that angles can matter a little for the shot… the problem comes in trying for those angles, not just accepting when your dispersion and variability put you there.

And in the millions of rounds we (Lou, me, etc.) have at our disposal… there are a LOT of "average golfers." They still don't matter much at all.

But, and this is the essence of it all: IF those ideal approach angles that matter and that can lower my scores are accessed accidentally, then they also must matter and serve as potential stroke savers if accessed intentionally.
Oy. We aren't past this, ten years after ESC, LSW, etc.? No. The small reward (if there is one, and there often isn't even when golfers swear there should be - an approach shot angle into a green is often a matter of a few degrees, and not nearly enough to matter much) is very seldom worth the much higher risk of trying to *intentionally* hit there. That's almost the whole point behind "angles don't matter."

Dustin Johnson "pulled it." Had he pulled it another eight feed, he'd have had to work his butt off to make par. He wasn't aiming there. He wasn't intentionally trying to hit it to two feet.

Not sure how relevant this is - but Hal Sutton recently did a Golf.Com interview.
I don't give anecdata much weight.

Erik,
No need to read 16 pages when the answer is obvious.  Of course angles matter as ALL golf architects and ALL great golf course architecture depend on them.  Yes the importance of angles can diminish or change with the skill of the player or lack there of and due to the conditions, etc but angles will always matter if for no other reason than for hole presentation and esthetics.  If somehow a course was designed where angles didn’t matter, it would be very boring to play and have zero visual interest.

I don’t know where shot tracking data exists on the spectrum of sports analytics, but I do suspect that its usefulness is tied to the same utility as all the modern advanced sports statistical analysis, sports as business.

At the recreational level, I just think it’s reductive. Actually I think it’s reductive at the sports-as-business level as well, but that’s wholly understood and beneficial. There’s a lot of the line. At the level of golf that MOST golf is played, in my opinion it becomes filtered and extraneous.

Which is also why the answer to this thread is OF COURSE they matter. I think the question golf architects have to ask themselves is this: do angles and hazard placement matter in my work? In answering that question, I think the crux issue very quickly becomes this: shot patterns are bigger than the targets provided for virtually every golf course. Until shot dispersion patterns become small enough (or courses big enough) that shot placement becomes largely moot and the game more resembles bowling than golf, saying that angles don’t matter seems more theoretically instructive than it does operationally relevant.

I don't necessarily disagree with anything you said above but as Erik would likely point out the statement "Angles Don't Matter" was in relation to scoring. I haven't seen all or maybe any of the data supporting that contention, it's hard for me to remember on a 16 page long thread that I've dipped in and out of, but I'm dubious of the proposition unless the data is based on approaches to an undefended green with similar contouring gradients from every angle. In other words, nothing that significantly distinguishes one angle of approach from another.


It's hard to imagine say, a 50 yard approach to an open fronted green not being easier ie. better scoring average, than say a 50 yard approach to the same green from another angle where the player has to play over a bunker.

hole presentation and esthetics.
I don't entirely disagree there (esthetics was in my ASGCA presentation), but that's not the context in which it's being discussed here.

That misses nearly everything.

It's hard to imagine say, a 50 yard approach to an open fronted green not being easier ie. better scoring average, than say a 50 yard approach to the same green from another angle where the player has to play over a bunker.

This has been addressed. Repeatedly.

Even in instances where they may be a small reward, trying to play for that angle is almost always more than enough to cancel out or reverse the reward.

If the left side is a slightly better angle, and your best line is the right-center, you simply say "wow, good for me!" when your natural dispersion happens to put the ball in the left side, but trying to center your shot pattern on that "better angle" side is often going to result in higher scores, even if you do increase the number of shots that you have from the better angle.

The risks often outweigh the minimal or non-existent rewards. Nobody's ever said there are never rewards.
Title: Re: “Angles Don’t Matter”
Post by: Mark_Fine on October 25, 2024, 11:15:23 PM
Erik,
When it comes to risk vs reward, if the risks and rewards are obvious, there is no real decision to make. Most times the risk/reward balance is not obvious and the golfer needs to think which is a big part of what makes great course design.  Angles play a large part in that thinking process. 

We both also know that most golfers are not sure where their golf ball is going after they make contact regardless of their intention.  As such I agree the value of angles diminishes.  But it is the presence of those angles that creates the need for a decision in the first place and that makes for interesting golf (even if one is not capable of the execution). 

I will finish with the old saying, “Knowing where to miss” is just as important as knowing where to try to hit your ball.  Much of the time it is because of angles.  If for example at a course like Pinehurst #2 you miss in the wrong spot, you simply just won’t be likely to hit the green or get up and down. Those wide fairways can present a false sense of security.  If you are on the wrong side of some of them, you simply can’t get the ball on the green.  And leave yourself green side with the wrong angle to the hole and you might be playing ping pong.

I bought into this theory after getting great explanations from Steve Smyers, Erik, and Scott Fawcette.  And, other experiences from tour pros I have known and/or worked with:


Q. Jack, how does that fw bunker affect your strategy?
A.  You want to miss it, obviously.


Q. Lanny, which side of the fw would aim for here?
A. What's wrong with the middle?



Q. Lanny, does an open front green help you?
A. If I am between clubs, I can use the short one and putt uphill. If I must come over a hazard, I club up with more spin, to be sure to clear the hazard and hopefully spin back toward the hole.  So, it's a different shot, but very doable...... from the fw.  That makes avoiding the rough off the tee paramount, and I play accordingly.


Q. Jim, are you going to challenge that fw bunker?
A. No, that is a big, big stop sign saying "don't go there."


Q. Larry, the next hole doglegs the other way.  What shot are you going to hit?
A. As always, a draw, either way.


Q. Larry, what about the tree 200 yards out on the right?  What shot are you going to hit?
A. As always, a draw, but I will hit it higher.



Q. Bruce, the next hole doglegs the other way.  What shot are you going to hit?
A.  As always, a fade, either way.


Q. What if it is a big honking dogleg?
A.  Then I hit a big honking fade......


Actually, if an architect combines a slight dogleg (like 10 deg.) and a narrow enough fw, it strongly favors one shot pattern or another, a la Pete Dye at TPC and others.  That's strategy, too.  Not only the position you aim for but the shot pattern to get there.  And most aim for the center of the fw and try to maximize their chance of success and especially to minimize the chance for bogey+.  The choice is to stick with your typical shot pattern, which statistically has a narrower dispersion pattern that playing a different shot pattern than is your strongest, to a target where that pattern leaves you less room for error.


I have never heard a good player say they are going to challenge a hazard, except perhaps a par 5 where they can gain a full stroke.  The small % chance of gaining 1 stroke on a par 3 or 4 shouldn't encourage a smart golfer.


-If we want to use old sayings, how about defense wins championships?


=Avoid bogey, because then you have to make two birdies to get back to level.  (Sort of like the stock market...if your portfolio goes down 10% (say from $100K to 90K) and then gains 10% the next day, you only have $99K.  Negatives always outweigh the positives, at least in most cases.


=Don't play the sucker punch!  There is a reason it's called that, you know.  And, it is more subtle than most give it credit for, i.e., not just an alternate fw for a tee shot, but aiming at the flag in almost any situation.


I am glad medicine has used science to move forward from bloodletting to microsurgery, and similarly, that golf is using the expanding knowledge/data on golf shots to improve strategy.  It is natural human progression in most fields. 


Someone dissed Erik for trying to sell a book here.  Hey, what were Ross, Mac, Tillie and others trying to do with their writings?  Yes, they were trying to change perceptions from the Victorian era of design, but there never really was any testing of the ideas (which were all very similar) that they proposed in their hopeful best sellers (LOL) I have seen a lot of evidence that people never really played that way, whether pros, or looking at my own mid handicap game, or those I play with.  In most cases, they try to miss the hazards from the top on down.

That's a different topic, but surprise surprise… I still disagree.

The risks of taking the flag on the far right side of the 17th at Sawgrass are obvious, as are the rewards if you pull it off. Players must still make a decision as to where to aim, how aggressive they want to be, etc.

It may be obvious from a strategic standpoint, but then again, as the 71st hole of an event… it's not always obvious even in those situations. Are you in the last group? Are you hitting first? What's the wind doing? Is it between clubs? etc. etc. etc.

We both also know that most golfers are not sure where their golf ball is going after they make contact regardless of their intention.  As such I agree the value of angles diminishes.  But it is the presence of those angles that creates the need for a decision in the first place and that makes for interesting golf (even if one is not capable of the execution).
You should read a bit of the many discussions around this topic.

Erik,
I don’t want hi jack this thread by getting into “The line of charm” vs “The line of instinct.”  But angles and risk/reward and temptation,… are what these terms are all about and they are why architects think about them often in their designs.  If they didn’t matter, why waste their time?

Mark, please read any of the discussions in the last six years on this. You've not really said anything here.

When we say "angles don't matter" in this and many other discussions, and if you imagine the specific example of a hole where the "better angle" into the green is from the left, but the left side of the fairway is guarded by a deep bunker:
It doesn't matter what the "line of charm" or "instinct" are strategically, to scoring, for the majority of golfers. They should almost all be aiming away from the bunker, avoiding penalty strokes or penalty-like situations.

"Angles don't matter" (except when they do, rarely) is a scoring/strategic conversation.

Erik,
We probably agree more than our posts are implying especially if we are talking about most golfers.  Most are just trying to make solid contact and play the same ball the entire hole. However, if they end up with a preferred angle, e.g. in the front of the green instead of behind the road hole bunker to a back hole location on 17 at The Old Course, most any golfer will be thankful for that angle!  I will leave it at that for now  :D

Mentally, yes…. And of course, that’s the crux of the matter as golf is a mental game.


BUT, Erik is telling us that golfers probably shouldn’t let it get in to their head because no matter what we think, scoring shows that there’s not a big difference coming in from the left or the right side (not talking on the Road Hole specifically).


I - for one - am willing to go with that… However, there is a bunch of nuance here. The reason scoring isn’t very different left to right is again possibly because of that mental side of the game, where because we believe that angles matter more than they do, we are far more aggressive from the “easy” side, thus sometimes making fatal errors, thus averaging out what will be more good scores with quite a few bad ones…. Whereas on the “difficult” side, we play safer, making less fatal errors…


…all of which circles back to mean maybe angles do matter more than we think, because they quintessentially change your mindset.


But scoring wise, never chase the angle. Hit for the place that keeps you out of trouble from the tee. Common sense really. “Strategy” has an over-emphasis put on it. Doesn’t mean it’s not important in many different ways but Architecture 101 has it high up on priorities… when in fact, if scoring is your aim, strategy means less than we think.

Ally,
If the data about angles and scoring is accurate and correct, then so be it, it’s correct.  How can one argue otherwise “when it comes to scoring”.  But I think we all agree if it were not for angles, the games would be much less mentally stimulating.  As Pete Dye said, “once you get those boys thinking,…”.


I would still take a bet with anyone that if you put 100 golfers with the road hole bunker between them and the hole and had them hole out from there then do the same from in front of that green, the scoring would be much different.  If it is not (for beginners it might not matter) then I stand corrected.  But one thing is certain, if you did the same thing but first removed the road hole bunker, the game is lesser for it.  Angles, usually driven by hazards and feature orientations, help form the essence of great golf design.

Angles do matter even on tour...
With a good angle, they will aim a little more at the pin... with the wrong angle, they will aim 15 feet away on the safer side..

The angles, right or wrong, doesn't generally turn into a hit or miss... architecture can only do so much against tour players discipline!

You tend to see small differences in scoring. To make it up a little with whole numbers:
"Good" side - 10% birdies, 60% pars, 20% bogeys, 10% others, "Bad" side - 5% birdies, 70% pars, 20% bogeys, 5% others could average out to almost the same with a shift in the distribution of the actual scores to par.

It's a non-negligible difference, but not a significant one.

I would still take a bet with anyone that if you put 100 golfers with the road hole bunker between them and the hole and had them hole out from there then do the same from in front of that green, the scoring would be much different.
Straw man, Mark. Nobody's ever said there's no reward, only that it's often over-emphasized, and the shot to put you in that better spot is often more negative than the positives to be gained from hitting your next shot there.

Mark,


Like Erik, I thought the Road Hole was a straw man argument.  An angle certainly matters on that green, when coming over the bunker to a green not deep enough to hold a shot, with potential 2 shot hazards front and back, vs playing along the long axis.


I don't know where Arcos measured these millions of shots, but I guess they are on more standard American holes and courses, where commercial limitations prevent designing such severe greens.  That kind of challenge is only present once on TOC, and one or two examples of narrow greens at 45 degrees would be more than enough for a course catering to the average golfer.

Erik,


May I give a synopsis/paraphrase of your position so I can better understand it?


*Chasing angles reveals negligible benefit to scoring and oftentimes a negative benefit. So angles don’t matter. Unless they do, which is circumstantial.*


If that’s off base please correct my synopsis so I can better discuss this subject with you.


More broadly, I have tried to pay attention to what you write on here and I’m beginning to see a pattern. It seems to me that your version of frank discussion is a long play to tell golf architecture fans that we’re overvaluing the art. I think many of us here are happy to defend our love of golf architecture to someone that thinks it’s overvalued. Certainly wouldn’t be the first time. I just don’t understand your insistence that these are complex and not-easily-understood themes and datasets.

Philippe, 


I sort of recall Jack Nicklaus, generally acknowledged as one of the masters of strategy or course management, before he decided to focus on the high fade (which I think has statistically been proven to provide a smaller dispersion pattern than "hitting the shot the architecture calls for") used to say he would aim at the middle of the green and pick a shot pattern that would slightly go to the pin location by a few yards.  I don't think he would aim at the pin as you describe. 


As always, I could be wrong, and for that matter, I am sure he chose to aim at the pin sometimes, when the match required it.  I understand that devotees to the basic strategic system laid out by Eric and others tend to have the discipline to never take the statistical sucker punch.  And I don't think Erik is telling anyone about architecture, just reactions to architecture and statistical facts, i.e.,


"Good" side - 10% birdies, 60% pars, 20% bogeys, 10% others, "Bad" side - 5% birdies, 70% pars, 20% bogeys, 5% others.  So, over 100 holes, playing only to the good side, you would expect:


- 10 birdies, 60 pars, 20 bogeys and 10 doubles, and you would be 30 over par from the good side. 


- Conversely, from the bad side, you would have 5 birds, 70 pars, 20 bogeys, and 5 doubles, and would be 25 over par.


Like most sports, playing conservatively (i.e., "defense" is generally the better play.)  That probably won't stop architects from putting hazards and angles out there for golfers to make the wrong decision about.  In fact, that is probably the point of architecture, then and now.  Angles do challenge the mind, and often defeat it, lol.

I'm puzzled why playing from the good angle would produce scores of bogey or better only 90% of the time while playing from the bad angle it would be 95% ? (my assumption is that "other" in your example is a score worse than bogey)


Or indeed from a good angle par or better would be achieved only 70% of the time as opposed to 75% from a bad angle. Is that really what the data is saying ?

My head is spinning. Why would the scores be worse once you have successfully made it to the good angle? Makes no sense. Isn’t the point that it’s not worth taking on a hazard to get to the good angle?

It's close, but I don't agree with the but after "Unless."

Not only do people generally over-state the benefits of being on one side of the fairway over another, they under-rate the negative value of chasing that angle. Furthermore, this idea applies to higher handicappers than most people seem to think.

There are rare exceptions, but both "rare" and "exceptions" are appropriate words.

If that’s off base please correct my synopsis so I can better discuss this subject with you.
At this point nobody's really come with anything "new" in the last ten years, so pardon me for doubting that you're going to be the first.

More broadly, I have tried to pay attention to what you write on here and I’m beginning to see a pattern. It seems to me that your version of frank discussion is a long play to tell golf architecture fans that we’re overvaluing the art.

Lots to unpack there, but… generally… no.

It's not a "long play" to discredit or diminish a bunch of things, it's just what we are coming to see as factual. It's not a value judgment, or a judgment of any kind: it's just an "is." There's no pattern… except to point out what I see as realities, or facts.

I also don't know where I've tried to sound as if I'm saying that these are "complex and not-easily-understood themes and data sets." I feel I've been saying the opposite for ten years, and have been frustrated at how many seem to have such a hard time understanding what I see as generally simple, straightforward things.

So, unless I horribly misread most of what you wrote, I don't know that you've pegged my perspective here at all.

As always, I could be wrong, and for that matter, I am sure he chose to aim at the pin sometimes, when the match required it.  I understand that devotees to the basic strategic system laid out by Eric and others tend to have the discipline to never take the statistical sucker punch.  And I don't think Erik is telling anyone about architecture, just reactions to architecture and statistical facts, i.e.,
Yeah. I love good golf course architecture, and think that even within these systems (which, to be frank, are all very similar because the data is what it is, and optimal is optimal*), there are ways to force a player to either make a decision. And, golfers are still emotional beings. They're not robots who can always choose the optimal target.

I'm puzzled why playing from the good angle would produce scores of bogey or better only 90% of the time while playing from the bad angle it would be 95% ? (my assumption is that "other" in your example is a score worse than bogey)
Jeff was quoting me, and I was illustrating how you could score almost the same from one side or the other side while creating a different distribution in the actual scores. An average is an average, but if it's the 18th hole and you need a birdie and don't care if you make par or double, you have to know how the strategy shifts, too.

Or indeed from a good angle par or better would be achieved only 70% of the time as opposed to 75% from a bad angle. Is that really what the data is saying?

For good players, that's often the case. They get a little more conservative (decrease in birdies, increase in pars), but they'll also make more higher scores. Hence, the distribution of scores changes, without the actual average moving a lot.

My head is spinning. Why would the scores be worse once you have successfully made it to the good angle? Makes no sense. Isn’t the point that it’s not worth taking on a hazard to get to the good angle?
Because even Tour players get a little more aggressive than they should, since they've all been told "oh, you can attack the pin from this angle." So they miss the green and short-side themselves a bit or something.

Anyway, a few of you have seemingly overlooked:

You tend to see small differences in scoring. To make it up a little with whole numbers:"Good" side - 10% birdies, 60% pars, 20% bogeys, 10% others, "Bad" side - 5% birdies, 70% pars, 20% bogeys, 5% others could average out to almost the same with a shift in the distribution of the actual scores to par.It's a non-negligible difference, but not a significant one.
I rounded everything into 5s for very good players to illustrate that the distribution of scores could shift even if the scoring averages stayed similar from that point.

As soon as the golfers are able to hit only their intended shot, we can talk about that…

We know what the sizes of a golfer's Shot Zone or dispersion pattern are. It's not as small as many would think, even at the Tour level.

I'm kind of surprised that we aren't seizing a little more on the "when the ball is rolling" part of the argument. As Erik (and others) have stated many times, "Angles don't matter unless the ball is rolling". It seems like a simple way to make angles matter as much as most of us want them to is a concerted effort to get the ball rolling.


It may be impossible to make courses firm and fast enough to get tour-level players to play along the ground, but I'm not really worried about them. For lower-trajectory, lower-spin players from the low-single-digits on up (i.e. most of the players on Earth), firm and fast conditions of the type that Ran and others have been advocating for decades would probably do the job.


I play a mom and pop 9-holer that keeps the ground firm and bouncy (and slightly shaggy) such that I land most irons a little short and bounce them on, including knock-down wedges. It's an effing blast! And that course isn't even a little strategic. Just imagine how much fun a course with some hazards or strategy would be with the same conditions.

The “angles don’t matter unless…” version of this debate could use some brevity. Angles do matter. As I’ve said before, shot tracking data in its current form has no way to account for a number of variables that have massive impacts to shot selection and result. And, what’s more, shot tracking data proponents have used really just one thing to assume validity of their data. The sheer size of the data set. But it’s still largely a two dimensional tool. We’re in shot tracking infancy and trajectory, ball speed, spin rate, firmness of turf, slope, etc etc ALL have a massive impact on how the shape of a golf hole and hazard placement affect golfers.

Ben, emotionally speaking, I don't disagree with what you and Sean say here, but I'm trying to stay cognizant of my biases, of which there are two big ones.

First is that I want angles to matter. I've been taught to think that way and I find it more aesthetically and philosophically pleasing.

Second is that on the Doak 2, 3, and 4 courses I tend to play, angles frequently don't matter. Not never, but we're talking once or twice a round in most cases. (I'd love to be playing some of the courses you and Sean are playing)

The second bias is why I pretty readily accepted the premise that angles don't matter as much as I'd thought (slash hoped). At a certain point I voiced the idea that at most courses, I could accept that angles didn't matter, because most courses weren't designed strategically. In response, Erik gave some examples where even strategic holes showed not much reason to believe that angles mattered (In honesty, I don't think enough data was given, which is why I'd like to see the stats for a large cross-section of golfers on holes that were recommended by architects for their strategic nature). But I could accept it given there was the following where everyone already seems to agree angles definitely matter: when the ball is rolling. The game is also more fun when the ball is rolling more.

Anyway, my journey on this has left me feeling like I was defending an ever-diminishing "god of the gaps". Which combined with the fact that at the average course (at least where I play) angles don't matter very often, is a bit deflating. That said, they do matter at least some of the time, so it's worth pressing strategic design still (along with the conditions that make sure it stays strategic).

Ben, the "angles don't matter" believers use "data" to suck the soul and magic from the game. They can believe what they want, but I will always look for the best angle and weigh the risk/reward because it is more fun, way more satisfying, and how I believe the game was intended to be played.

Angles matter because they offer choice. Even if folks play the safe route, which they should likely do most of the time, angles matter because a choice was made. If folks want to play bowling alley courses with very few recovery options that’s cool…angles don’t matter. I am rarely interested in that type of golf even if I believe it has its place in modern architecture.

Ben, the "angles don't matter" believers use "data" to suck the soul and magic from the game. They can believe what they want, but I will always look for the best angle and weigh the risk/reward because it is more fun, way more satisfying, and how I believe the game was intended to be played.


Craig,


I think that is fair enough. And whilst I genuinely think that angles matter less than all us golf architect nerds want to believe (because it’s such an easy touch point), I will always design and build a whole bunch of angles and “strategy” because even if it partially works - even just mentally - I agree it makes the game better.

You are perhaps correct that angles maybe don't matter as much of the time as many think but would you agree that it is the gca's job to try and make them matter ?

I agree it seems sad, but like so many other things, time moves on.  In golf, equipment has made the game more straightforward and tilted the scales towards more (but still not enough) test of accuracy.


I mentioned angling fairways 10 degrees or so.  It sets up the advantage of hitting a certain shot pattern off the tee to maximize that shot's chance of success.  Statistically, there is no benefit to have an improved shot on the next one.  TOC is certainly a hole that requires placement in certain spots to avoid a near impossible shot, and probably any angled green has that to an extent, especially if the approach shot can come in over safe ground vs flying over a pond.  That said, my tendency as an architect was to widen a green that might logically suggest a shot coming in over water.


One more thing I have mentioned in the past and will repeat here.  When working with Jim Colbert (who would play any type of shot the architecture suggested in most cases) I noticed he actually thought that coming in from the bunkered side of the green was preferable.  Again, he wasn't worried about ground balls or low running shots.  To him, it was like teeing up close to OB on the tee - it widens your dispersion angle away from the OB side.  Coming in from the "good side" i.e., along the long axis of the green reduces the angle to lateral hazards from, say, 20 deg to 10 deg.  He would aim at the far side of the green and bring it back slightly (a la Jack) accepting a downhill putt if he didn't curve it enough and blaming himself if he overcooked it and went into the hazard.  Stats now show that he really couldn't control his miss left as much as he thought he would block out the hook.  (I have seen golfers do that and double cross it, going way left, but that must be outside of the 90% dispersion acceptance level.


Angles also mean something to the shortest players on tour on par 5 holes.  While the big names will fly a high iron into the green on their second, there are a lot of 280-290 hitters still on tour, and a par 5 of 550 yards or so still requires a fw wood with role for them to reach the green and compete.


Another case is the 45 degree angled greens, of which TOC 17 us a example.  They may not provide an advantage from one position or another, but you certainly have to match shot line and distance on those greens, also a strategy.


You may recall that Pete Dye ended up bunkering long par 4 holes on the inside at both LZ and green to make the hole play longer.  The old "bunker inside the LZ, bunker outside at the green" isn't the be all end all of golf course architecture.  It may work in both running situations, and perhaps on downwind holes, which take the spin off approach shots for most, making hitting the front of the green (and chancing the green hazard) more challenging from the wrong side.


So, there is still strategy related to angles and aim points, it's just less interrelated to the next shot, and more focused on hitting the current target, not the next one, which if you think about it, should be job 1 on the tee shot in any case.


And again, is there any reason to rely on something wrote in architecture golden age, but statistical dark ages?  :D   For 100 years or so, everyone took those books at face value, never really proving them up via field testing.  Until recently!

I'm kind of surprised that we aren't seizing a little more on the "when the ball is rolling" part of the argument. As Erik (and others) have stated many times, "Angles don't matter unless the ball is rolling". It seems like a simple way to make angles matter as much as most of us want them to is a concerted effort to get the ball rolling.
I for one love fast, firm golf. Last year for about three weeks the course I play most often got really fiery. It was great. You could hit some low long-irons off tees and the ball would still roll out for quite a ways. You could still hit shots and stop them somewhat on the greens (though the first hop was still making that nice "thud" sound), but it changed the way the game was played. So fun.

It may be impossible to make courses firm and fast enough to get tour-level players to play along the ground, but I'm not really worried about them. For lower-trajectory, lower-spin players from the low-single-digits on up (i.e. most of the players on Earth), firm and fast conditions of the type that Ran and others have been advocating for decades would probably do the job.
Yup. But the USGA tried to get everyone else to be "down with brown," but the golfers out there still want their course to be their own Augusta National.

I loved what Pinehurst looked like in 2014… but it didn't even look like that in 2024.

I very rarely play courses and conditions where angles don’t matter.
You keep saying that, but… It's quite unlikely.

Angles do matter.
Just saying it doesn't make it so.

And, what’s more, shot tracking data proponents have used really just one thing to assume validity of their data. The sheer size of the data set.
That's not really true. I mean, you need a large enough sample size to make relevant, valid conclusions, but you can look at how 5-7 handicappers play one specific hole. etc.

We’re in shot tracking infancy and trajectory, ball speed, spin rate, firmness of turf, slope, etc etc ALL have a massive impact on how the shape of a golf hole and hazard placement affect golfers.
I think you're saying that in high hopes, and I think you're going to be disappointed. The simple fact is whatever spin rates a player is generating, we capture the results of that shot.

Just saying things doesn't make it true, Ben.

Ben, the "angles don't matter" believers use "data" to suck the soul and magic from the game. They can believe what they want, but I will always look for the best angle and weigh the risk/reward because it is more fun, way more satisfying, and how I believe the game was intended to be played.
And you're welcome to do it. Sometimes I take on the shot that's not as strategically smart, just because I want to, as well.

Nearly 20 years ago I began sharing my opinion on Tobacco Road. I don't dislike TR, but my opinion really seemed to bother some people. My opinion boiled down to "there's a lot of visual stuff going on, and a lot of crazy shots you're begged to try to pull off… tempted to, goaded into… but if you could avoid doing that, and play pretty strategic golf, it was a golf course on which you could put together a pretty good round even if you're not playing your absolute best.

Is that the most FUN way to play Tobacco Road? Probably not. Lots of people love to go for the second shot on 11… or whatever. And that's all up to them.

The "angles" discussion has, from my side, almost always been about scoring. Not what you like or enjoy or find stimulating.

Also, it's not about "belief."

I think that is fair enough. And whilst I genuinely think that angles matter less than all us golf architect nerds want to believe (because it’s such an easy touch point), I will always design and build a whole bunch of angles and “strategy” because even if it partially works - even just mentally - I agree it makes the game better.
And, like I said in my ASGCA presentation… 95% of golfers aren't aware of this stuff, and won't be for a loooong time. The game's best are, and a good chunk of the serious golfers are, but even among them, there are still plenty out there who think that putting is how you get from a 5 to a scratch. :D

Erik,


I’ll reiterate another way. I didn’t learn much in statistics but I did learn that specificity matters. Aggregate data is useful. I’m not arguing with you there. What I am arguing is that there is specificity missing from the two-dimensional results-only data for your position. Saying that the result is the result and that it takes into account the mountains of breadth from player to player ignores specific circumstances.


I had an offline conversation with Lou one time where I—at the time a 12 something handicap—screenshotted my distance data. He replied that I was in some crazy percentile, like 0.6% of players with that speed and that handicap. This admittedly anecdotal situation told me what I’d always suspected about applying aggregate data to specific players. 


In your example above, I’ll just say that not every 5-7 handicap is the same. I think our current version of shot tracking data supposes that that fact doesn’t matter. Everyone should revert to the mean over time and play accordingly. I am saying that isn’t correct. Applying the angles don’t matter position to two 12 handicaps, one with 85mph driver club head and one with 115 driver club head seems a bit reductive. No?

I’m with you, Mark. I reckon 90% of golf I play is on links courses (I’ve played 5 rounds out of 60 away from the links so far this year).


But, by far the firmest course I play is my own one and it is the only one where coming in from one side of the fairway to the other really matters… because on every other links course I play, I stop the ball quicker and it nullifies almost all approach strategy (at least when not severely downwind). And I’m a low spin player for a lowish handicap.


In other words, it needs to be REALLY firm to really make a big difference.

You're a better player than most. But it's not just ability to stop the ball but also the ability to consistently get the ball up in the air and carry it the right distance to get over the hazard. It's possible to not hit the ball properly and see it run onto a green where the green is open but you don't have the same lee-way when the angle you've got means you have a bunker in the way.

Kinda, but we can also look at specific things, too. Whether you want to call it narrowing the focus, or drilling down… whatever… the specific examples tend to line up with what we see generally.

He replied that I was in some crazy percentile, like 0.6% of players with that speed and that handicap. This admittedly anecdotal situation told me what I’d always suspected about applying aggregate data to specific players.
Give a specific thing if you want to talk about it, but also… there are of course exceptions out there. Doesn't mean they're necessarily worth discussing much.

In the past I've asked for examples, and people throw out holes where they're happy when they find themselves on the left or right side of a fairway, but they're still almost always holes where there's no way in heck you'd ever actually be smart to aim there.


In your example above, I’ll just say that not every 5-7 handicap is the same.

I think they're more alike than you might think. I think, as an outlier yourself, you're thinking there are more outliers than there are. If they were more plentiful, they wouldn't really be outliers.


I think our current version of shot tracking data supposes that that fact doesn’t matter.

That's not really true, as you can look at stats for individual golfers. With the Tour players we work with, we do just that. One of my guys is really good with his wedges. Another is tremendous at right pins (he plays a fade and his confidence is about 5x as much with a right pin). We adjust the strategy for them, but it's still… almost the same strategy. The same general tenets hold up. We're shifting lines and targets a little bit.

Everyone should revert to the mean over time and play accordingly. I am saying that isn’t correct.
I haven't said that either.

One wonders if you might ever concede the same from your own position. I don't think that anyone is doubting your data set. However, your interpretation of that data does not, in itself, constitute fact. What you have instead is just one of many theories about how to approach the playing of the game that is no more or less valid than any other. What separates us, in part, is that whereas my approach to the game involves spending time outside in the fresh air and hitting some shots with my buddies, your approach appears to have a more single-minded (borderline robotic) devotion to scoring. And whereas my focus is on hitting fun, or "dangerous," shots (because I don't too much care about my score), your paradigm seems cautions people AGAINST interacting with the various design features (all but dismissing the relevance of design professionals). Neither of us is wrong, but it's as though we're playing different games.

Put another way, angles can, should, and DO matter.

Part of this debate/squabble seems tied up in the fact that there is some aura placed around words like "strategy" and "angles" that puts an emotional charge into them, so those of us with aggregated centuries and millions of golf shots' worth of experience of our own know that there is bone-deep truth around terms like those.


Ultimately, that's why "Angles Don't Matter" clickbait is effective. On that level, you have to hand it to Erik and Lou and others - they've figured out some good marketing copy in addition to their data.


But just because it's clever doesn't make it correct. After all, every golfer is "chasing angles" on every single shot of every round, even when playing by the data-driven rulebook. Any affirmative decision to aim a shot in a particular direction is presumably intended to set up the next shot from some sort of advantageous angle relative to the hole. Whether you choose to ignore your own tendencies and purely turn your golf brain over to the data is of course your choice as a golfer, but it's still Erik & Lou & Co. telling you to "chase" certain angles.


So it really isn't "Angles Don't Matter" at all. It's "Only Our Angles Matter," which, though less catchy, is closer to the reality of the data-as-God golf approach.

I would take one step further which is one of the cornerstones of strategic golf design. You are playing for an angle even if avoiding or delaying risk. You are playing for an angle if you follow the numbers. Why? Because strategic design offers the choice. If a course is strategy designed, the vast majority of players can’t escape dealing with angles one way or another.

I think the difference is in chasing an angle for where you want to play your next shot vs chasing a position to play your next shot from. The first is saying something like "the green is angled to the left, so it's better to play from the right side and I'll aim that way". The second is more like "I don't care what the green looks like - I want to keep my ball out of trouble and as close to where I'm going as I reasonably can".


Put another way, from a minimizing your score point of view, your tee shot strategy would be the same whether the green is angled left, angled right, angled straight or whatever. If a hole doglegs left or right then that would potentially change where you want to aim, but that's more from the perspective of hitting it as close to the hole as you can, rather than trying to find a specific side of the fairway.


I think Erik is right about the whole "when the ball is rolling" thing. There are for sure some people who can play for the angles we are discussing. One of my mother's friends was a decent golfer - she didn't hit it very far, but she hit it VERY straight. She could hit it within a few yards either side of her target with driver. She also hit it fairly low and the ball would roll (which goes hand in hand with the not hitting it very far thing). So she could absolutely play for an angle. Her shot pattern was probably 15 yards wide with her driver though.


PGA Tour players have a roughly 65 yard wide shot pattern (I think at around 95%), so for them, playing to a side of the fairway to get a better angle at the green is ill advised. Playing for a side of the fairway because the other side is serious trouble on the other hand is perfectly reasonable. Take 18 at Sawgrass. Half the players wind up in the right rough/trees there because the penalty of that is less than the penalty of hitting it in the lake. I wouldn't call that playing for an angle though. And if the best players in the world are picking their target based on where the trouble is rather than the angle to the green, then what in the world would make a long hitting 5-7 handicap think they should be chasing angles?


Having said all that, as Steve said, it's really about what your goals are. If you want to go out and take on trouble and get that rush of pulling off the hero shot, then have at it. No one is saying you can't do that. If your goal is to shoot the best score you can on a given day, then pick your targets appropriately and play to them. You'll score lower that way in the long run.

Riiiiiiight.

No. "Attack every pin regardless of your lie, the distance, the trouble, etc." is not as valid as the strategy I talk about and share with my golfers.

That's the very nature of the conversation: it's entirely about scoring.

We're not talking about whether angles are visually appealing (they can be, and stuff like this was at the end of my presentation to the ASGCA last year). It's almost entirely talking about scoring. Sheesh.

After all, every golfer is "chasing angles" on every single shot of every round, even when playing by the data-driven rulebook.
Except that's not the way anyone uses the term. Yes, even Scott Fawcett is aiming somewhere when he gets up on a tee of a par four.

No.

No, you're not.

I think the difference is in chasing an angle for where you want to play your next shot vs chasing a position to play your next shot from.
Yup. Put another way, it's "chasing an angle into the green" versus "choosing which lie is going to offer the best chance at a good approach shot" (i.e. fairway, not the deep bunker guarding the "good angle" into the green).

The first is saying something like "the green is angled to the left, so it's better to play from the right side and I'll aim that way". The second is more like "I don't care what the green looks like - I want to keep my ball out of trouble and as close to where I'm going as I reasonably can".
Yup. And I didn't quote the rest of what you said, but that… too.

Her shot pattern was probably 15 yards wide with her driver though.
I used my daughter as an example in my presentation, too. Especially when she plays from 6300 yards or so, she has hybrids into some greens, and is accurate enough with her driver that her dispersion pattern is pretty small. She can shade to a side of the fairway a bit.

PGA Tour players have a roughly 65 yard wide shot pattern (I think at around 95%), so for them, playing to a side of the fairway to get a better angle at the green is ill advised. Playing for a side of the fairway because the other side is serious trouble on the other hand is perfectly reasonable. Take 18 at Sawgrass. Half the players wind up in the right rough/trees there because the penalty of that is less than the penalty of hitting it in the lake. I wouldn't call that playing for an angle though.
Nor would I, or anyone other than the people who have tried recently and in the past to define everything as "an angle" so that they can conclude, despite ample evidence that it's not what anyone is actually saying, that they are right and that angles matter.


And if the best players in the world are picking their target based on where the trouble is rather than the angle to the green, then what in the world would make a long hitting 5-7 handicap think they should be chasing angles?

There really is a lot of defensiveness on this thread when the only message is pretty straightforward:


- Good course management says completely forget what the best angle in to the green is. Play the tee-shot that is most likely to keep you out of trouble but ideally on the fairway.


That is a true statement. Even in firm and fast situations, I am just trying to hit the fairway (anywhere on the fairway) with my tee shot. It is - of course - the argument for 70 yard wide fairways. That approach to design gives slightly more room for angles in to the green mattering. But it can come at the expense of an element of challenge in your tee shot.


The above - really very simple premise - does not mean that architects stop using angles because they can get in to everyone’s head (even if they shouldn’t) and they add to the game, even if only aesthetically.


It also has nothing to do with designing “diagonals” (which can be mistaken for angles) which are more about choice of distance vs risk.

Ally


I'm not sure I totally agree with that. If staying out of trouble and playing percentages is good course management then perhaps playing away from every best position if it comes with a risk might in some circumstances hold true, but only depending on what you are looking to achieve eg. a decent score over 18 holes or winning the hole in matchplay. It also assumes that having decided to play safe that the player can still hit a shot that stays out of trouble. All your doing is increasing the margin for error rather than eliminating it. It also assumes that the players ability to rectify the error eg. getting up and down out of the bunker, is less than say the players ability to capitalise on a more aggressive approach. I'm sure there are other caveats that could be added undermining the basic contention.

"The angles discussion has always been about scoring."  In your mind... Seems a bit arrogant on your part.
No. Nearly 100% of the time, when the phrase "angles don't matter" has been uttered, debated, etc. it's been about scoring. It's been about how it affects the shot, and the likelihood of hitting it close, or hitting a "good" shot. It's BS to pretend that it hasn't been, and posts like yours there come off as a way to salvage some sort of "see, I was right, they do matter, because I'm going to change the context and pretend it was about this other thing the whole time." For example…

This site is about golf course architecture and angles DO MATTER in golf course design.
Angles in this conversation haven't been about the esthetics. They've not been about draining water properly and efficiently. They've not been about how it makes you feel. If you want to talk about design, or drainage, or how this slope blends into that slope… find a different word. The "angles" conversation has been about scoring for a decade plus. Pretend otherwise if you want, but that's all it'll be: pretend.

- Good course management says completely forget what the best angle in to the green is. Play the tee-shot that is most likely to keep you out of trouble but ideally on the fairway.
Yes.

That approach to design gives slightly more room for angles in to the green mattering. But it can come at the expense of an element of challenge in your tee shot.
One of the reasons why angles don't matter to scoring is that the angles are often so small. On even a 40-yard wide fairway, a shot played from 5 yards from the left edge and a shot played from 5 yards from the right edge from 160 yards are coming in from angles that are  less than two minutes on a clock. When you overlay the shot pattern over the endpoint… it becomes apparent that even a shot that would appear to skirt a bunker or whatnot from the one side and needing to cover it from the other isn't quite that way - both are either going to end up in it almost as often or both are going to fly it and it doesn't matter much for that reason.


The above - really very simple premise - does not mean that architects stop using angles because they can get in to everyone’s head (even if they shouldn’t) and they add to the game, even if only aesthetically.

Those slides are from the "summary" section, but I went into the bullet points in more depth in the presentation itself

Ball is rolling covers the first three:
"Other" is partly the catch-all other type of stuff Craig wants to pretend the conversation has been about with the artistry of the architect to slope this shape to mirror the background mountain or whatever. It's in there because, every so often, someone tries to pull a Craig and ignore the reality of what this topic has meant for the last ten years.


"Other" also covers the rare exceptions like the 12th at ANGC (a pretty small target) where the literal angle of the green favors lefties over righties - pulls go longer, pushes go shorter. Most architects seem to think that you can get away with one of these types of designs that punish a player for simply which side of the ball they play from in a round, but more than once in a round of 18 holes might start to get you into trouble.




It also assumes that having decided to play safe that the player can still hit a shot that stays out of trouble.
No, it doesn't. Maximizing your chances of shooting a good score does not guarantee a good score. How the heck have you been reading and participating in this conversation for ten years to say something as off as that?


All you're doing is increasing the margin for error rather than eliminating it.
No shit.


I'm sure there are other caveats that could be added undermining the basic contention.
Nothing you just said "undermines the basic contention." At all.

Angles matter the most on best most thought provoking golf holes.  This is not rocket science.  For example, I would wager with Any pro that they can’t get the ball up and down on #10 at Rivieria if I am allowed to choose the angle of their approach shot  ;D

- Good course management says completely forget what the best angle in to the green is. Play the tee-shot that is most likely to keep you out of trouble but ideally on the fairway.



Ally


I'm not sure I totally agree with that. If staying out of trouble and playing percentages is good course management then perhaps playing away from every best position if it comes with a risk might in some circumstances hold true, but only depending on what you are looking to achieve eg. a decent score over 18 holes or winning the hole in matchplay. It also assumes that having decided to play safe that the player can still hit a shot that stays out of trouble. All your doing is increasing the margin for error rather than eliminating it. It also assumes that the players ability to rectify the error eg. getting up and down out of the bunker, is less than say the players ability to capitalise on a more aggressive approach. I'm sure there are other caveats that could be added undermining the basic contention.

Hi Niall,


I think it's safe to say that optimizing strategy does not eliminate the possibility of putting the ball into trouble. As it happens, there are a certain number of penalty strokes/awful spots you'll wind up in if you play optimally. Heck I watched one of the players in the US Open at Shinnecock hit one onto Southampton GC from the 12th tee. If you never hit it in the water/OB, then you're very likely being too conservative. Basically you don't want to aim too far away from the trouble. Take 18 at Sawgrass again - you could aim it 20 yards into the rough on the right. You'll virtually never hit it in the water if you do that, but you'll also play 80+% of your second shots from the rough and it will be very hard to make many pars and you'll make a ton of bogeys and probably a few doubles. Better to aim it right quarter or even right edge of the fairway, so maybe 3-5% of the time you wind up in the water (talking PGA Tour level players), but you'll have 50-60% of your shots from the fairway and 35-45% from the rough.


The way the strategy works is you have a certain number of shots that you would expect to complete the hole in from every position on the course. From 200 in the fairway, for a PGA Tour player, that's I think about 3.15 strokes. The rough I think is about a 0.25 add, so 3.4 strokes from 200 in the rough. Then there's sand and recovery areas (think in the trees). Then you map out where your shot pattern will put you for every possible target. Add up all the likelihood of where you'll end up with the strokes to hole out and then minimize it. Obviously no one is doing that for every shot, so what Erik's book and Scott Fawcett's DECADE are doing is coming up with a model for how to figure out something close to optimal on the fly. The fun part is that what feels instinctively like the right thing to do is frequently not optimal, so there is a certain amount of fighting what you "want" to do with what you "should" do. Getting past that is a skill and the ability to do that is likely going to be impacted by how much left-brained you are vs right-brained.


For an example of how hard it can be to figure that out - especially for a higher handicapper, take the 5th hole at Pebble Beach. Par three with water right. There is a bunker short and a bunker long left. The water is obviously not a good spot to hit it, but if you're a 15 handicap, then your shot pattern is pretty large. If you aim at a target such that your shot pattern does not include the water at all, then you're starting to bring the rough behind the bunker on the left into play. That is a really hard shot off a downslope towards the water, and a fairly hefty number of your second shots are going to wind up in the water. Better to go in there with your first shot than your second, so ideally you'll be including some penalty area bound shots in your set of outcomes from your tee shot.

I'm late to the party here, so forgive me if these points have been made.


While Lou/Scott and others have championed that "angles don't matter," they are frequently fond of the same courses we are, although there are some exceptions (i.e. Fawcett's disdain for the 2nd at Talking Stick).


I tend to agree with Erik that when it comes to scoring, angles usually don't matter enough to pursue them. It's hard to argue with statistics at the end of the day, and the wealth of data thanks to Arccos makes it harder and harder to argue. Dodo Molinari was recently on the Fried Egg pod and mentioned that TOC may be the only place angles matter and that Augusta was one of his favorite courses.


But angles do two things: create variety in a golf course you may play many times and create shots which are advantageous for some golfers and not others.


A great example of this is the way the 3rd and 9th greens at Pasatiempo are oriented to benefit left handed and right handed golfers respectively based on dispersion patterns.


So while we may argue semantics over whether to play for them or not, there isn't much question as to the fact that angles should still be an integral element of any design, and that with that context, they absolutely matter.


It's not as much about throwing out what we have learned from over a century of golf course architecture discussion as it is adapting that information to modern data and accounting for changes within the game.


FWIW, learning more about analytics has unquestionably made me a better golfer and adjusted the way I play, but only affected the way I look at design in the sense of looking at how we create desired outcomes (I.e. if we are trying to create a "safe play," we have a better understanding of what it takes to accomplish that)


It has also emphasized how critical the design of greens are to creating a "good" and "bad" side to miss on. Part of why so many of the analytics guys love Augusta.
Title: Re: “Angles Don’t Matter”
Post by: Michael Felton on October 31, 2024, 04:00:20 PM
Good points Connor - I do ponder from time to time what actually makes a golf course good or bad. I know there are lots of things you could talk about like challenge or variety or quirk or things like that. I also know it when I see it, but I struggle to actually put into words what makes a specific golf course great and another not great. I suspect that is what really differentiates someone like me who enjoys golf architecture, but would struggle to put a remotely decent golf course together (as witnessed by my couple of forays into the armchair architect challenges we've had on here on occasion) vs someone like Tom D or the other architects on here who probably could put words to why one golf course is better than another. I also think it is fun to try and think of what you could do to make someone using DECADE struggle.


Separately, I know that we talk about chasing angles and what not - I think it's really tough to come up with a situation where it would make sense to chase an angle on a tee shot that isn't either somewhat contrived (split fairway for example) or just easy either way (like a 90 yard wide fairway where you could actually aim for one side or the other). As Erik says, angles matter when the ball is rolling. The one time that the ball is rolling way more than any other is on or around the green. If you're 200 yards out and have a green with a tier in it - for sake of argument let's say the left side is higher than the right side. Flag is on the right side, but fairly close to the tier. If you hit it on the top tier, you either have to hole your putt down the hill or hole a 25-30 footer coming back to get out of it with a par. That's a situation where it would make a lot of sense to aim in such a way as to minimize the chances of putting it on top. I think you could describe that as chasing an angle.

Nice point. I think this is where this or a new thread should go, since so many younger low handicap players are using it.  We've beat the horse on whether angles matter.  If not, or even if so, what else matters to these players?

It strikes me that this statement is confirmation that angles do matter.  There is a best angle into the green.  So angles matter, just (very) rarely so much as to alter the correct strategy off the tee (which is (nearly) always to play away from trouble rather than improve the resulting angle into the green.

Agreed. I think if you go back through the 18 pages, you'll find people saying angles matter (sometimes), just not enough to chase them (most of the time).

 8)  WELL I WISH I HADN'T BUT I SPENT 3 SITTINGS TO GET THRU THE LAST 18 PAGES... yes angles can matter, conditionally and of course with exceptions, sundry caveats, and not usually in the modern pursuit of scoring.  Reminded of TE Paul's "big tent" theory covering all things golf.


Personally I'll play angles more often than not, when I can see or imagine them, simply to keep the old aiming and distance controls tuned up.  I was taught to pick a target, select a stick, and try to hit the ball there.  Fun when it happens, a continuing challenge when not and an amateur game in the end for me. 


Big data is cool but what's your null hypothesis?

The ball is rolling on #10 there, and it's also a very narrow green effectively. I've asked for examples of holes where angles "matter" to even a 5 handicap, and people almost never come up with anything.

Angles, as Edoardo Molinari said, almost never matter (in the way that it's always been discussed). But what does he know, eh? What do I know? You're (general you) arguing anecdotes and stuff you've always believed against actual data, millions of golf shots, by handicappers of all levels.

I think it's safe to say that optimizing strategy does not eliminate the possibility of putting the ball into trouble. As it happens, there are a certain number of penalty strokes/awful spots you'll wind up in if you play optimally.

Yup.

There are exceptions, certainly. They're rare.

It's hard to argue with statistics at the end of the day, and the wealth of data thanks to Arccos makes it harder and harder to argue. Dodo Molinari was recently on the Fried Egg pod and mentioned that TOC may be the only place angles matter and that Augusta was one of his favorite courses.
Me linking to that podcast was what kicked off the renewal of this topic and discussion.

But angles do two things: create variety in a golf course you may play many times and create shots which are advantageous for some golfers and not others.
The 12th at Augusta was on my slide in my ASGCA presentation. Like the 10th at Riviera, it's more of an exception (and requires a pretty shallow green to do it).

I typically hit a draw with my mid and long irons. I try and hit my drive where my second shot draw will produce the best result.
Your aiming spot (for the ball's finishing position) isn't going to differ much than someone who hits a fade.

It strikes me that this statement is confirmation that angles do matter. There is a best angle into the green.
This fails in two ways:

a) Often the "better angle" produces the same scoring average as the "worse angle." Thus, the "better angle" is often not the "better angle" at all. It may be visually more appealing or something, but it's often not actually better.
b) You address it here:

… Rarely so much as to alter the correct strategy off the tee (which is (nearly) always to play away from trouble rather than improve the resulting angle into the green.
Yep.

For those who have read this far, I've got another good example of a rare time angles matter, and it's a combo of the things we've talked about before:

(https://p197.p4.n0.cdn.zight.com/items/o0uAd6Dn/8cd83b5b-d629-4a09-9eea-77383e1e3fec.png?v=2a6fdcb8476a40be8597fe0b79a22ed2)

It's from the recent video from Andy with Tom about Sedge Valley. It combines width (the angle created here is about 40°, not only about 8° or 12° like we see from many approach shots from the edges of the fairways) and a shallow (from the right-side angle) green, which makes the Shot Zone overlap a lot of the bunkers).

Like the 12th at Augusta, which is also very shallow, it creates its "angles matter" by tilting in a direction that favors lefties: pulls go longer, pushes go shorter.

If you've never considered how GCA affects your ability to score, or influences your scoring, in fact if you've never kept score while playing golf and you only ever consider GCA because of how it looks, how visually appealing it is to you… then you might have a point.

I doubt that's the case. The design affects scoring. Yes, the beauty of the design is relevant (though not to this particular topic), but "risk" and "reward" and "attack" are all related to scoring.

But it sure seems like angles really matter this week at Bay Hill.  Several holes where hitting a shot down the middle of the green vs carrying water or bunkers into a tight pin sure seems to be making a noticeable difference.  Today they even moved the tee up on 17 to play to that right side pin which looks almost impossible from the back tee.

Yes, he is of the opinion that removing trees is a huge problem. Tour courses need more trees and and if there were more trees the ball rollback wouldn’t be necessary.

“Fairways Don’t Have Proper Sides”

These are both quotes from the data manager of Arccos Golf, Lou Stagner. I decided I was tired of being a golf nut that sucks at golf and I’m working hard to get better. This led me to data analysis and Arccos Golf. Turns out, all the stuff I thought I knew about getting better at golf is sort of old hat.


That said, this modern take on shot tracking and by default, scoring, also has an affect on golf architecture. What’s your viewpoint when you read quotes such as these? Keep in mind that Lou Stagner has over 600 MILLION golf shots from which to draw conclusions.


They matter if you play hickories.

For the elite golfers, the only line that matters is the direct one as far up the hole as possible. If it's in the rough, gouge it out.

Of course, there will be instances that a green contour will be so severe as to make things better from a specific angle... but how many holes do that... especially modern ones?
