Thanks for your response Dan.
For me, it was nice to see someone using simple physics and constructing models that were essentially the same ones I had constructed.

I also can use muscle to knock a large nail in with one stroke. Positioning and centripetal force seem to be the most important factors. But when I do it with relaxation, the feeling is much different. Therein is what I was trying to say - albeit poorly stated as you pointed out.

Learning that a sequential form of relaxation was a big eye opener for me. And testing it with a hammer was fun because I could immediately tell the difference. It made me trust the process.

Thanks for responding
