Well I think there are some factors that can slow the game down a bit. Some players start trying to slow down so they don't get eliminated before the bubble, but many start doing so by having plenty of time to maybe double the stack and not to worry about the bubble. On the contrary would play pressing the other stacks. How long the 7 hours is the life of the grinders of mtt, who does not like, can try to play other modes, cash and sit go, where the cash has no fixed time. to go out, and sit go takes much less time than a tournament overall.
