Total Immersion origins/theory

I've heard of pre-setting the wrist (if that term is accurate). But, I'm not sure how prevalent it is in practice. Here's a slow motion video of Sun Yang's 1500 World Record race. In particular see :54 - 1:11. No noticeable wrist tilt at the start of his catch. Sun Yang Front Crawl Technique (Under Water & Slow Motion) - YouTube As Kirk suggests, we humans are in an awkward position at the start of the catch and are forced to work through an inefficient movement to get to a point where we can apply power more effectively. Yeah, but it looks like he does it around 1:48 to 2:15. And I thought I saw a few strokes where his wrist tilted up, which is supposed to be a no-no. But then I think you could see about anything in a swimmer's 1500. So many strokes.
