nolanryan5714: I've been shooting a lot of 31s and 30s, now I'm at 64.30 but still don't know when TM hits
I just congratulated a friend who turned TM. His current avg is 62.90 (but that will change to a higher avg when he posts his 1st ranked round)
Looking at his profile he shot a 30 and 31 in succession, which would indicate he was between 63.5 and 63.2. So it would appear that a <63 would be the avg which would trigger the step up from Master to Tour Master.
Hope that helps, and good luck.
