Just a question because it has been awhile since I have played 12, but when someone quit you could get the points but not the win, so I wouldn't be looking into being behind a 2-1 or so guy so much as they may have played more games than you but just never had a game get finished.
I would be more concerned about the points your getting, but that could also be due to the game not actually being out so players aren't given the correct "rating".
But this will be interesting to watch when it actually is released because this could be a big problem to some, but me I could care less because cheaters rule the leader boards
