That’s accounted for with the time I set. 12 games for LotS with LotS tournies going from 5.5 to 7 hours. Not to mention there is significantly less room for deadtime here with half this tournament being BO1.
When I made the first round BO1 for LotS we pretty much always hit 5.5 hours or so.
I kept track of the game lengths during LotS because it tended to be a good metric to gauge which series to give to casters, I'd get like 2 of 12 series that would go over an hour in total time.
