There is a bug when u calculate ur games abandoned
For example in your profile u can see how many games u left, played, won and lost.
Total games = won + lost + abandoned
So if u have known how many games u in total have played, how many u have lost and how many u have won, it is an easy sum to calculate how many u abandoned.
But the abandoned games is bugged for everyone.
Ive played 2708 games
lost 509
won 1078
but abandoned 12.
Maybe it resetted. But it should be 2708 - 509 - 1078
