Not an answer but you might be interested in looking up “parachute landing fall,” a method parachutists use to distribute the force of hard landings throughout their body. I guarantee every stunt person knows the PLF and the stair fall is probably somewhat related to it.
I’ve noticed they definitely have a method for rolling down hills in movies, they always do it like this Princess Bride clip. Nothing but their arms and back and knees touch the ground.
