Chinajohn:to see their real average rather than some artificially reduced one?
Score history is the place to look to start to get a better feel at any rate.
Some TLs have incredible averages then look closer and things like only 3 RRs played in the tier, and so who could tell??. Some may play only Beth F9 in their CC (same as at Legend except no zero wind free comps at TL that I have seen), and a Whoop Dee Doo low average.
In the end even the top players are not going to shoot what you might expect as often as you think, just going by the best ever 500 average. Their score histories (consistency) are impressive enough though. Top players for a reason, no mistake:)
So much WGT could do with the stats, but I doubt one overall average can be too indicative of much anyway.
