Like others I was saturated at TL (>200 RRs) with my WGT average going down. After the change it appeared I was grandfathered my best 200 rounds and WGT average. After playing an additional 550 RRs, watching the WGT average go up, I hit the 750 threshhold.
Since then my WGT average has gone down with good scores and stayed the same with bad scores. Only now a 'bad' score is anything 31+! LOL
Have fun, hit 'em straight, and hit 'em as few as possible,
John
