Sully:
Good topic. I'm not sure I agree with the premise. Augusta seems to have emerged as a course with about four half-par holes, with the rest being a collection of a few easy-par holes, and a bunch of tough par/really tough par holes.
Some stats:
Four holes on average this year played under par -- the four par 5s. The average score ranged from 4.77 (15) to 4.84 (13). All yielded far more birdies than bogies, in ratios of roughly 3:1 up to 4:1. The back nine par 5s yielded far more eagles (8 at no. 13, 3 at no. 15, compared to 3 total eagles on the front nine par 5s), but also far more double-bogeys or worse (12 on no. 13, and 10 on no. 15, compared to a total of 8 doubles or worse on the front nine par 5s combined). In short, the back nine par 5s -- based on this year's stats -- played much more as true risk/reward holes than the front nine par 5s. But in general, the par 5s were the only holes on the course that I might consider true half-par holes if that means having a legitimate birdie option.
The only other half-par holes on the birdie side were the short par 4 3rd, and interestingly the 12th. No. 3 had a near-equal distribution of reward to risk -- 44 birdies, 44 bogeys, and four doubles. No. 12 had 40 birdies and 38 bogeys, but also 9 doubles and 3 others, all of those presumably water-bound tee shots.
Everything else on the course seems to be a tough par. Even the second-easiest par 4 -- no. 14 -- had nearly twice as many bogeys (55) as birdies (32). It may not be a tough par, but it doesn't quite fit my notion of a half-par hole (on the birdie side of things) if it's yielding far more bogeys than birdies.
Holes 11, 10, 7 and 1 (the four toughest holes this week) all played to a stroke average of 4.25 or higher -- which to me is a half-par hole on the bogey side.
I think the course now has four birdie/half-par holes (the par 5s), a few others where there is a decent chance of scoring birdie (3, 12, 14, 16, maybe 6 -- although all of those on average scored over par for the week), and a bunch of hard pars/half-par holes on the bogey side.
This during a week when arguably there were three very good scoring days, and only one really tough scoring day.
