I like it, I like how every team is required to use it, but I do agree that it should be on fewer legs. More than half the legs but fewer than every leg. It makes things interesting, but after a while the episode break is "Oh man this team is having trouble with the other detour. They may not make it much further. Oh wait, this didn't mess them up much at all and they'll finish in 3rd or 4th."
Also, when does this start back up? Tomorrow?
