Anecdotally it definitely narrows and I would say its most significant with shorter putts.
This year Ive been doing some of my practice at another local course with much better greens and the difference in making those shorter putts is huge.
Really? Tiger is the ultimate competitor. I can’t imagine he disliked the RC. My opinion is not popular but when you’re a world class professional athlete with millions of dollars and have way above normal resources and luxuries I don’t think it’s much to ask to show some enthusiasm to play on a USA team. Poor guys have to go to the gym at 5am? Oh, gosh that’s just awful. Never mind the millions who do that then go to their monotonous 8-5pm job. Shut and play golf. Have Chauncey make you a nice drink on your private jet on the way home. 😳😄
