Remember that if a player shoots more than 60 points below their rating, they don't get included as propagators. Several potential props shoot more than 60 points lower due to the OB on that course. So what happens once their scores are excluded from the SSA calculation is the SSA goes lower which means their ratings end up even lower. That makes those 1100 rounds even tougher to reach.

When we've done studies comparing older Pros to younger Pros of the same rating, they average the same rating on resonably balanced courses. However, as you might expect, younger players of the same rating shoot better than the older players on mostly open courses with longer holes like at the Memorial. Older players shoot better on wooded courses than the youngsters. The effect isn't huge (2 shots over 18 holes) but enough to see when you look at cumulative ratings like your neg 364 calculation.
