By the looks of it , ridge, I would say WGT put in place another tool for you to use when checking out your opp. It may be in place for future stuff but that would be up to WGT and any other answer is speculation on our part.
It (the match stats) has already helped me in that it recorded a match I played against a particular opponent which happened to be a ladder match that went unreported. I was able to verify the match.
What would you use them for?
