I disagree categorically with this. In baseball, the team that commits the most unforced errors tends to lose the game, but the team that scores the most runs always wins. Usain Bolt doesn't have 8 gold medals and 3 world records because he has perfect form (I just learned that he has scoliosis, leading to "imperfect" form, whether that made him faster or slower than he would otherwise be is apparently a subject of some debate), but because he's fast. It is frequently the case that the best at something defines "perfect" form. And anyway, Bolt doesn't run marathons, because he cannot sustain that kind of performance for 2 hours. I hear what you're saying, I can't count the number of times I've seen truly bonkers tricks in freestyle skiing and snowboard competitions, from people who screwed up their 2nd or 3rd run, or couldn't stitch together a coherent run around that one trick, and so came in near the middle of the rankings. But the winners were not significantly less impressive, just blunder-free. A lot of time, the winners were the peak performers moment-to-moment but sustained that performance for much longer.
