I was wondering if anyone new about what the putting percentage for pro's are from 33 feet? lets say out of ten shots how many are they going to make when practicing.

2.75

9.997 out of 10.

If you're saying right at 33 feet - as in just INSIDE of the circle - I'd put the number in practice at 7-8 out of 10 for the guys at the top of most championship level events. Maybe 8-9 out of 10 for the guys that are premiere putters. But thats just an estimate based on personal experience - I don't watch the very best when they're practicing ;) Though I'm sure it couldn't hurt my game. :P
