Wait? So it doesn't keep tracking the match whether it's a victory or loss after you leave it? I thought that was at least the case with Battlelog titles that it will afterwards count as either win or loss. I mean those Battlelog reports will pop up afterwards if you leave prematurely and there's your performance data.
@Teal_Pipo_FredoIt does. I think there has been a long-standing myth about this.
If you participate in a match (read: shooting / interacting) you will take the win / loss and any stats you accrue while in it.
