Gymnastics... isn't constrained by simple applications of Newtonian mechanics. Gymnasts can perform moves that no one's carried out before—that no one ever thought of carrying out before. Now, the sport has a scoring system that's built to reward that. In theory, yes, there's still an upper limit. There are only so many different possible elements in a routine and only so many possible connections between them, and each one, at least for now, is worth at most 0.7 points. But this new upper boundary is less like a perfect SAT score than a 1.000 batting average: a limit so far out of reach it might as well be no limit at all.
