I think it may be Turf Inked that determines this then. I wanted to find out myself, but when my Glooga finally took the third spot over Reeflux, I realized I had out turfed it and got that last win both in the same game.

The amount I've painted with Mint Decav is still way lower than TTek, actually, so it can't be that. It's like 1.2 million vs 1.4 million. I wouldn't be surprised if it recorded how long each game lasted or something but really I have no idea.
