WGT don't have to worry about anything, this was in terms and conditions about being a beta game:

this case, all player history and data will be erased and each player
will return to beginner status.

So wether you pay to play or not, its at your own risk. I know when entering some ready go's my meter might skip once in a while, i know it might stop you scoring a birdie or 2, but we KNOW what to expect when we enter, but we stil do because it's one of the best features of the game.
