If you showed up at a Shotokan tournament, they'd expect to see something that looks much like the Shotokan kata. And there would be principles (as others have pretty clearly pointed out) that would be judged, even in an open competition. So, just throwing your hands around would get nothing. Now, if you assembled an interesting new kata, there's no reason that couldn't win in a competition, so long as you are doing it well, and it feels cohesive.Agreed Its ridiculous so basically If I wanted to I could turn up to a shotokan tournament and enter as a black belt (even though I've never trained it) and just throw my hands around and pretend to know what I'm doing and I could get a gold medal....how's that fair in any way.
