I'm a 4, and I watch LPGA from time to time, and I think I could win maybe 1/25. Every now and then I'll shoot par on a difficult course. Thing is, she would have to shoot over par on that same day. And she could very well go 8-under and run me off the course on my best day.
My home course is a difficult course, rated 77.1/150. A 4 doesn't shoot par (72) on that course, no way no how. Perhaps on some pushover course rated at 70 or so, but not on a difficult course. A lot of delusional thinking in this thread.
wow, that's a hard course. I don't think the average LPGA player would break par there either. The consensus guess is that the equivalent for a male is somewhere between a +2 and scratch.
