I remember in freestyle aerial skiing they banned quad backflips because after a lot of analysis they determined it was too dangerous, that it was likely the skiers would exceed the length of the outrun. It made sense but this does not at all. Aspiring gymnasts can use foam pits, crash mats and spotters to learn new moves. It's called progression.

Why do the number of flips make you exceed the run out? Do they fly farther? Or are they going faster than they would have opted to on an easier move?

  Both essentially. You need more height to do more flips, which means you need more speed coming into the jump, which means you will fly farther horizontally. Some of this can be modulated by your takeoff, but only a small amount. Projectile motion/physics dominates.

Out of curiosity (not to draw any parallels to this situation), were there any skiiers who performed the quad backflip in competition before the ban?

  That is hard to nail down: Here's Frank Bare in 1983 https://www.youtube.com/watch?v=RTb0zCgybnY https://www.youtube.com/watch?v=RTb0zCgybnY Earlier than this Steve Corbett's flip has disappeared from the internet but it did happen in 1975 at Whistler BC: Corbett's quad backflip was the first one ever done. He was 80 feet (24 metres) in the air flipping four times. You can see him here at the 16 second mark: https://www.youtube.com/watch?v=afv8Ts-zTPQ https://www.youtube.com/watch?v=afv8Ts-zTPQ I think though Jean-Marc Rozon was the only one to do it in competition. He was the leader of the famed Quebec Air Force that dominated Freestyle Aerial Skiing in the 80's. You can see his quad in the second clip above at six seconds. In 2012, Matt Chojnacki 'landed' a quad twisting quad backflip. I'm not sure if this was in competition, it would have been dsq'd if it was. My guess is training: https://www.youtube.com/watch?v=druWqXZnoeU https://www.youtube.com/watch?v=druWqXZnoeU
