Underline by Daryl. When examining the "Lever", consider where the "Force" is applied and not what generates it.

Fine by me.

For a swinger, a significant part of the linear force is applied as an axial pull force through the left arm and through the shaft. With extencior action the work load will be channeled from the right side of the pivot as well. The same basically goes for a hitter. If he can play golf.

I sustain my earlier claims that pressure point #4 has a limited influence power wise. It's the pulling (and the pushing) through the shoulders that delivers the real horsepower whether you hit or swing.
