Wgt does have the ability to change the parameters of a putt, in other words "how perfect putts have to be struck to fall in the hole", but you don't see it very often except when the hole gets smaller, then you hear from everyone who is "Mute" when every f'n putt is dropping in LMAO!
If they would leave it on the tough end probably 1/3 of these people would be gone, or in the "WGT" is rigged thread, so that won't be happening anytime soon!
