ArchibaldBunker:
how are people averaging in the 60s and 50s?
is it simply the top equipment, or "cheats"?
The "average" on WGT is not really an average, it is just the average of your best rounds. For each tier there is a different amount of rounds that counts, but as soon as you reach that number, your "average" will never go up, no matter how bad you play. It will go down though, each time you hit a score lower than your current average. If you have a 63,2 average you can play 20 rounds with more than 80 shots without affecting the average, then if you hit a single 61, it will go down.
So if you play a lot and make a very good round now and then, then your average will be very low.
