A 2*2 tournament is underway; everyone is fitting perfectly within the time limits!
Yes, gathering 4 people is harder than gathering 2. But perhaps, along with this factor, the fact of a long timer also plays a significant role? Why not take into account potential shortcomings of the already ongoing—undoubtedly wonderful—2*2 tournament and try in advance to reduce possible forfeits and unplayed games specifically because matches will on average take well over 10+ hours?
Of course, one could say: if you don't like waiting 40+ min for a move, then don't get involved; and generally, you can't even play 1 on 1 with a 10 min SoD timer, you bunch of rushers. Or, we could try together to find a timer solution acceptable to the absolute majority. This is a general discussion aimed at helping the organizer; in the end, the final word belongs to him.
