Bob,
can't say anything about your play - maybe you've become a bit cramped by the new situation (just a guess)?
Other than that, a few facts & opinions:
The average will only go up for a certain time, because the calculation started from scratch when you tiered up. Only a bunch of your best scores will be included there eventually.
The awards won't come in as easy as before because the gaps in counting can get quite high - look into your awards section. OTOH, I like the crystal ones most - shining blue...
As a TP, I liked to go for the scoring awards of the different courses - good practice!
Balls wear - a steady income to WGT.
The "very fast" greens at TP level are different to read & play - practice is the key, more than a new putter. FWIW, I still carry the starter...
