No offense to Ryan (who is right about almost everything he said in his interview), but there doesn't actually have to be something dramatically different about the way world champions do moves. Better athletes with better timing do things more effectively. Sure, there may be slight personal nuances in terms of hand/forearm positioning, or a rhythm of back and forth movements to shift weight and set things up while trying to shrimp on bottom etc, but generally speaking, they're doing the same move that experienced hobbyists and seasoned competitors who aren't quite at the top level do, they're just doing it with more success. They recognize the time to strike better, hit the move harder, commit to it with confidence, and do it technically correct. It really can be and often is just that simple.
Lots of people image that there is some secret trick or tactic when they hit their ceiling at something only to look up and see others surpassing them, but sometimes, it just comes down to other people being better, whether due to innate ability or overall depth of experience. It's easier for a proud person to think there's some discrete learnable thing they're missing, and if they could only discover it, that they could quickly rise to the top too. It's much harder to come to terms with the fact that you just might not be as good, no matter what you do. I'm not saying this is the case here, but I think it's a very real possibility that is being ignored because it's unpleasant to think about.
