Why would it behoove me to measure parts of my game against the average of my class of golfer?
So that you can judge your relative strengths and weaknesses. Combine that with an honest assessment of your limits - Brian Gay is likely not going to find an extra 25 yards throughout the bag, so he's gotta compete in other areas - and you can figure out how to set up the best game and game plan for yourself.
For the average golfer (amateurs, I mean, not the "class average"), comparing yourself against your class is fine, but comparing yourself against a class of golfers in the next better class is often very illustrative. It'll show you where you need to gain the most strokes to move up to that level. For example, a 9 wanting to become a 5 might need to get on or near (we coined the phrase "near-GIR" or "nGIR" in LSW) just three more greens per round. Maybe developing a trouble shot will help with one of those, and not having a duck hook off the tee twice a round will take care of the other two. Or whatever. And then a small improvement to the short game and putting and, bam, he's a 5.
The Scott Fawcett video about the 5th at Sweetens Cove left me completely unsatisfied with this line of player development. I suspect there are a great number of players on the PGA Tour that would not be considered tacticians on the golf course...maybe they never needed to develop that skill. Maybe the 5th hole at SC should be a driver every time...but his rationale just didn't resonate well. Curious to dig in a little deeper but I really need to read these two books.
I thought the video was pretty good, except for a few things (like laying shot patterns from other holes entirely, played in different conditions, and average players are
much worse from bunkers than PGA Tour players, which is all he ever really talks about). It goes to what I said above: for a lot of shots that a PGA Tour player might face, the angle is irrelevant. Angles matter more for average golfers, many of whom are bouncing the ball in or planning on a little roll-out, or who don't have the distance control to just fly a bunker and stop the ball within a few feet of its landing spot.
Now, if for some reason a player is
actually worse from 40 yards than they are from 100 (in general) - which would be quite rare, really - then the strategy has to change for that individual. Or he's exceptionally wild off the tee. Or whatever… strategies can change. I watched Brian Manzella give a lesson one time about how the average AoA with a particular club was -4.1°, and he spent the entire lesson trying to get the student to -4.1° with that club… but it's an average. That means there are PGA Tour players who are -1° with that club, and some who are -7° with that club. So that the guy was -6°… is that really the biggest flaw? Probably not (IMO definitely not in that case). My point there is that "averages" aren't always great, particularly if we don't know the standard deviation, and applying "averages" to PGA Tour players or average golfers is full of pitfalls if you get careless.
Again, that's why I don't like the "rigidity" of DECADE. In LSW, we talk about some averages, but only in ways (we think) that can be eye-opening in the sense that someone would have to be an EXTREME outlier to not take note of them. For example, how close average players should be before they aim at the pin instead of toward the fat side of the green. For higher handicappers, we don't even advise they do that at 50 yards. For even single digit players, aiming slightly toward the fat side of the green from 50 yards STILL produced lower scores. But if some individual is flat out deadly with his wedge, or the hole has a big tier just to the fat side of the green, those numbers would shift a little and the strategy should, too.
One question I haven't seen so far answered is whether shot pattern reduces that 65 yard cone? In theory, set up for a fade, aim to left edge of target, bring ball back to target. Shouldn't setting up to avoid a left shot (barring the 1% chance of a double cross) half, or at least reduce the shot dispersion cone? Good players have been using that theory for years, anyway. Do stats prove that wrong?
Another example of why I'm not totally in love with all of Scott's stuff. The 65 yard wide zone is the combined pattern of ALL players, not any one player. The players who make up that pattern may be aiming at different spots. Some may hit a draw, others a fade. Some of those shots are misses (he does say that - some will be in bunkers, etc.). But it is not one player's "Shot Zone" as you'll read about in my book, Jeff.
The stats don't say that hitting a fade eliminates one side of the rough or not. To know this, on the PGA Tour, you'd look at any individual's left and right rough tendencies. Some players are skewed one way or the other, some are pretty even. I teach my players, and a lot of PGA Tour players play the same way, to have a "shot cone." Let's say they play a fade - their ball should never start left of the left side of the cone, and should not fade right of the right side of the cone. But that cone might be 50 yards wide at the end, so they're missing left and right, depending on not only the shot, but where they're aiming the center of that cone.
Here's an image.
That has a bit more to do with confidence than raw scoring, as shots that "leave" the cone for a time can still end up close to the hole, as you'll see. But generally speaking, on the PGA Tour, a guy who plays a fade rarely hits a push-draw accidentally. So the cone idea has a lot of weight.
And as you noted, yes, PGA Tour players (and honestly most golfers everywhere) should find their one stock pattern and stick with it unless forced to change it (i.e. to curve the ball around a tree to get to the green, or on a tight dogleg). It's a bit of a jack-of-all, master-of-none type thing. Better to be a master of your fade or draw and not a jack who tries a different shot every time. Unless you're Tiger Woods, maybe. And even that didn't work out when he was struggling - he had a two-way miss with his driver because he didn't know if he was going to fade it, draw it, block it, hook it…
