Bateleur0: I am two weeks into the game and am a level 35 Pro with a 73 average at the moment and he is a level 50 pro with a 150 average. Go figure.
Of course, that doesn't mean a thing. If he has a 150 average that means he's not playing any ranked rounds that count for average.
The only rounds that count for average are ranked rounds, excluding custom courses, par 3s, and par 5s.
So, I'd be careful reading anything into that 150 average.
