I'm trying to pick out the most important of these nuances, most of which are just applied physics, and explain them in a way that makes them useful. That part is really easy. Where it gets tricky and frustrating is that nothing stays in its neat little box.
Each thing affects the other thing. Structure is important (but sometimes structure is utilizing free-fall, the exact opposite of rigidity), but compounded with exploiting gravity, and ... and ... it is amazing. Combine and practice some of the principles right and you have contact telepathy.
None of it should be completely new to most well-trained martial artists-- but some of it will have been just lip service and some is in the motion but not really explained or understood by the instructors. Structure is a good example. I've known many people with excellent structure who didn't know it. It was just something they picked up by training and when they became instructors they assumed that everyone just 'picks it up.' Some do. I think most don't, and it's one of the reasons why many students never live up to their instructors. Learning some of these very critical nuances are left up to luck.
All of these are in the physical drills of almost every art that I have seen, but you can get through the drills, you can get through the entire syllabus of most systems and never actually learn or understand the stuff that is in there. You can do the techniques 'well enough' or even very well, and entirely miss whole principles.
But it is frustrating to write. All of the chapters so far refer to multiple other chapters... so which goes first? Each chapter starts with an experience where that particular principle was critical, but almost all of the principles played a role in almost all of the stories. Leverage points make better sense if you understand base and Center of Gravity first, but base and CoG are easier to grasp if you understand leverage.
It's going to take a lot of work from the readers, I think. I'll make it as easy as I can, but in the end people can only effectively read one thing at a time, so the flow will never be the same as a force incident where multiple things are happening at multiple levels.
Training people is much easier than writing.
