OK, but everyone just states it as fact. No one quantifies in any reasonable manner. How much softer and slower are the greens, how much shorter is the rough, pin placements? how is that quantified. Are you taking this from some tournament set up guide or what? The senior tour sets up everything but its majors shorter, slower, shorter also. Their set up guide clues you in to how much. In the last 5-7 years they have added some length and green speed, although rough is normally still shorter. When no clear comparisons are made of how big the differences are it sounds more like a you throw like a girl put down then a reasoned comparison.
I'll quantify it from hand experience since I've played Bulle Rock both right before and right after the LPGA used to have a major there. The only real change that happened to that course for an lpga major was they made the greens a touch faster. They leave the rough at the normal height, pins are a blend some are a little tucked but most are accessible and the greens are as soft as any other day there. I'm not saying LPGA players aren't very talented because they are very good but their course set up are nothing like the mens in terms of majors. The other thing I've noticed is at men's US Opens there is always a green or two that they seem to almost lose control of by sunday. I want to say winged foot or shinnecock they had to water them mid round on sunday plus 14 at Pebble was borderline out of hand last year. You never see that happen during a womens US Open so that would tell me they aren't letting the greens get nearly as hard and fast for the women.
