That's a bit of a selective response Chris, ignoring the components which make a float happen. IS is about a type of efficiency not used in normal body movement. Thats why i earlier stated I never realized the degree to which you had to relax and never push back.
I will respond fully later.
It could be that I'm selecting the parts that seem relevant to me. I think that's a fair assessment.
I'm trying to find the parts where you actually explain the components of IS. When I read them, to me they just sound like a really complicated way to say something, that can be said in much more plain terms.
To me, I believe that the problem we are really having is imagery and words. I know I keep saying this. But I really think that is the difference and not an actual physical one.
I'm trying to see the difference, I'm listening.
