I dont know how the Client counts stuff or what file it uses. But M.A.T is going to use a known good file that is used through the entire game process.
At first I was debateing if M.A.T should count just the multiplayer games or if it should count both multiplayer & AI games. Then I got to looking and decided to have to different panels one for AI and one for other Players.
The key here is that for validation reasions (This will be for the "Offical" Releases only. Not the "Test Versions") both players will need to have M.A.T running. This way the files can be crossed verified with each other so we can grantee noone is cheating.

Nothing worse then someone that wants to boost his Stats by cheating the system.
