Mark Aurel raised this point in my Palmy rule section.
Here is the ruling.
Both players must agree on the outcome of the game. If you remember I stated this at the very beginning. Therefore if the outcome is not clear and a player disputes the game then that game is forfeit and must be replayed.
So it is totally up to yourselves as players to do the right thing and come to a mutual agreement on this issue.
I would sincerely hope that no one would stoop low enough to intentionally dc from a game they were obviously losing. Lets play with honor people and there should be no problem.
