This was a small one so, being young, I think was a bit more into it than most I've seen. During the periods when you can't see it on the video, I could see pretty clearly with my polarized sunglasses and I will swear that there was not a muscle twitch or fin movement. It was like it was carved out of wood.
I think the game is to get into the quarter wave in such a way as to surf along on the pressure differentials without any expenditure of energy, sort of like going down a hill on a skateboard.
