If you leave at any point in the match it doesn't count as a loss or break your streak, including leaving right as you lose to the Nightlord.
That being said, my record is legit. I got to 180 right before EDs came out and I play too many randoms lately to go beyond it now most likely.

in that case you're likely a relic cheater anyway if the murk/relic rewards at the end don't matter to you
