Again, this is a trial experiment in response to overwhelming player requests. WGT only gave us what we asked them to try.
Like uneven lies, it will be tweaked going forward. Yes, it's unfortunate that a player can quit, and eventually the others quit, too....ruining everyone's percentage.
But, I'm hopeful there will be a fix for that at some point.
The quitting percentage feature is a potentially valuable tool if adjusted correctly.
