John K,
The second paragraph of your second post comes close to my idea of shot value evaluation. Also agree with many other posts. I have never seen a great definition in concise form, and have tried for years to come up with something. My imperfect idea at the moment, is listed below. Obviously, more scientific than some would like, but when "evaluating" anything, it seems like you do need to go this route.
First, I think we look at the value of each shot, giving each shot a rating based on the system below.Then, we compare the overall compendium of shots to see if the course has good shot values.Obviously, if we have some kind of Doak (or Golf Digest) scale per shot, no course is coming out a perfect 10.For the whole, the question is how many times can you break the rules and still have a course with good shot values? Certainly, there could/would be a way to rate the exception (like blind shot) that works well.
1. The Absolutes - No unplayable shot.
a. For Average Players and above, this would include forced carries beyond their max carry distance (considering wind), usually about 2/3 average driving distance.
b. It also includes extremely difficult shots, like:
i. Requiring a uphill long iron shot from a downhill lie.
ii. Water on right with wind blowing right to left, i.e., must aim over OB or water to reach green or fairway)
iii. Shot over something (bunker lip) but under something else (tree branches) (at least from normal play areas)
2. Statistically reasonable “doable” shots –
a. Targets of such size, shape, and angle and contour to accept a well-played shot.
i. Shape – Not so extreme (fairway or green) to effectively reduce target area
ii. Size –
1. Fairways at least 10% (pro)-15% (am) of expected tee shot distance, i.e., 30 -27 yards for average player and good am works as minimum
2. Greens at least the size of USGA Slope chart recommendations.
a. 10% (pro)-15% (am) width
b. 10% (pro)-25% (am) depth
3. Adjust targets for wind conditions, like deeper greens on downwind shots to account for less spin, more rollout, wider greens in crosswinds, etc. (as per George Thomas)
iii. Angle – Generally
1. Bend in Prevailing Wind Direction on all shots
2. Steeper Angle as Approach Shot Shortens
3. Max Angle leaves at least small opening from the edge of fairway.
iv. Contour – Generally Higher in Back to Help Stop Shot (the Redan is an exception, allowable if there are means to land ball short)
3. Visibility. (While there are exceptions to this rule, they better be good to make up for what most consider an obvious flaw. No visibility, no strategy)
4. Options- Shots with 2-3 fairly obvious options are much better than a shot with one option. Requires some light thinking.More options just get aggravating and confusing to most.
5. “Best” Target Location/Optionsthat “suggest/reward” a best location with a clear advantage, on the tee shot usually by:
i. Shorter approach– Always an advantage
ii. Better angle – Usually a frontal opening without hazards in between
iii. Green contours assist approach – An upslope facing one side of the fairway to help stop their shot)
iv. Preferred stance and lie -Usually a level or uphill lie to make the shot easier
v. Better vision to green – Not as important given yardage books, but still providing psychological comfort
vi. Taking major hazards out of play on either shot-Golfer’s fist task is to avoid potential disaster!
Sometimes, those locations/advantages can vary by wind, pin location or by golfer abilities, rather than the absolutes just above.
6. Features “suggest/reward” one shot /pattern.As Jim Colbert once told me, “There are smarter dudes than me, but if the wind blows left, the target angles left, and my lie slopes left, I think I will hit a draw.No sense fighting physics, and that maxes out my chance of success.
He, and most other good players I speak with say the same thing.A good shot value is one where most signals suggest a preferred shot, making it a matter of judgement and execution.A shot with a hook lie and fade target is harder to judge, involves more luck, and rewards nothing strongly, which contributes less to “having to hit all the shots.”
7. Temptation/Dilemma – This should rate higher for some, but maybe not all shots, or there is too much excitement.At least a few options ought to have a high degree of risk and reward, i.e., possible eagle/birdie to bogey/double bogey, or birdie to bogey.Carry Hazards and narrow fairways should be arranged so golfer has 51-67% chance of success, based on average game.
8. Recovery – Most (not all) hazards ought to offer a chance at recovery.While there is no magic formula, in general, golfers won’t challenge a hazard if the chances of recovery (i.e., can reach green) are less than 51-67%. (variation depends on golfer, place in round, etc.)
Then of course, the best courses compare all the individual shot values to the others.
9. Balance - Not all golfers can “hit all the shots” so there needs to be balance to not play favorites:
1. Among shots that favor
a. accuracy,
b. length,
c. finesse.
2. Wind Patterns – Shots with wind from every point of compass
3. Shot patterns:
a. Hook vs. Draw (Winds from all compass points)
b. High vs. Low (actually, most winds favor this)
c. Spin vs. Roll Out (Typically tail winds combined with frontal openings vs head winds)
10. Variety – Similar to Balance, but also considers differences in wind variation, sequence and order (i.e., short, long, short type approach sequence, different approach shots by par, hole length/type, etc.) An extreme example - Manhattan CC in Kansas has a front nine that favors the draw, a back nine favoring the fade. There have been some monumental swings, which are fun, but in theory, I would want to keep the match closer, longer for more fun and excitement, so a ranking based on alternating fades and draws Pete Dye style make some sense.
There you have it, a nice 10 point list (because who doesn’t think in terms of lists these days) that in my experience, most good players would judge an individual shot. If you gave each shot a point for every preferred "value" it has, and averaged all 36 shots (I figure putting is always a matter of trying to hole it out, and has constant value, but obviously, perhaps rolling greens ought to figure in somehow) you could average shot values for a course. May have to work on including putting next!
Would be an interesting exercise, as you can tell I think above, but in the end, not sure it would change anyone's rankings. I know there are exceptions to any rule above that still seem to work, but not sure how you would rate those. I also would need to figure a way to judge shot relationships a bit better. going back to putting, most feel that most holes should reward two difficult tee to green shots with easier putting, etc.
As I said, about as fully formed as a post oatmeal bowel movement. Also, apologies, as the formatting in Word doesn't translate fully, making it harder to read.
