I dig this update. This is the Superleague fix that I found WPPR 5.2 to be missing the mark on.
Also it makes sense that TGP is calculated per amount of play a game gets. I haven't read all of what you have for Pingolf yet, but it sounds very promising.
Interesting though, why the change to selfie leagues when both you and Shep are running one? Seemed like the boost to coin drop was a big point in its favor, but will it still be doing that with the lower value? Or do you have a format change in store for next year?
