Does backing out effect your CSR?

Like backing out of lobbies before you vote.

Not out of lobbies I don’t think. But if you leave mid-game, then yes, it does affect your CSR.

Doubtful. It does affect quitters though. Now hopefully I won’t have to worry about joining mid-session losing games and have MY CSR affected.

If you leave a match mid-game, it counts it as a loss.
