Hey all, I'm new and have a simple clarifying question.

Every speed runner jumps down to the warp tubes at 4-2. Why does everyone jump and not simply fall? Does this not lose a frame rule?

Current world record at 2:20. My thoughts is his jump takes him all the way to the far wall, then he has to turn around. Why not run off the ledges and turn around? He's losing frames vertically and horizontally on this fall.

Same thing at 0:25, why jump and not just fall?
