Everything I saw in that youTube video fits into the definition I gave about our out-of-line accumulators seeking their inline position. The second half of the video is referencing a swinger's sequenced release, but he covers a lot more than that. Hitters use a simultaneous release.
If you really want to understand it all, you should do some research through existing posts. There's a lot of good stuff in these forums, and again I can't emphasize enough how good the oldest posts from Yoda are in the archive sections.
I'm looking at a lot of the old stuff, but it is a lonely business reading it by oneself over a long period of time is not the same as having a dialogue about it, which is more interesting. It's not all that is understood correctly and therefore needs to be confirmed or corrected. If nobody wants to answer - that's a chance I'll have to take.
