Total Matches Played

Ok so im sure most of you have noticed this before but your total matches played on your profile dont match the number of wins and loses. And dont say desertions count because they cant.... Here is why.

Total: 4454
Wins: 1433
Loses: 2965

Difference of: 56

# of Desertions: 1527

Here is my profile.

(they may count as loses?)

So where do they get their numbers?
