I vote zaqwert.

The last round lasted 4 hours. This round has lasted around 13 hours. I think it would be unfair not to declare zaqwert the winner of this round.

DD: If you are including yourself in the competition then you should probably either let other people close off your rounds after a certain amount of time has passed or else state when the round will end when you start it. This will help remove any accusations of bias.
