I just want to say, check out the scores from the lower ranking tours like the Hooters tour and the little mini tours in FLA and CA. Most of those are played on the same courses you and I play, and they are putting up some numbers and these are the little tours.
At the course I used to work at here in St louis that had a Hooters event. The course was in good shape but not pga tour shape, and somebody shot a 62 with hole in one on a par 4!! 25 under won the tournament. there were many 64-65s , par 72
