I don't want to Thread-Jack but this is disturbing.
Also, and one small point. ..... If COAM exists with both Swingers and Hitters, doesn't that prove CF exists with both Swingers and Hitters?
Here is some real disturbance,
(Berndt in blue)
"CF doesn't produce any swing speed... there is a CF/CF pair alive... Caught in the middle you have a cocked left wrist... The two forces pulling from each side of the hands will cause or contribute to uncocking of the right(sic) wrist and release."
So he says CF doesn't produce any swing speed, but does cause the wrist to uncock, which does produce swing speed!
Even more disturbing is the fact that he ignored my question about Hitting and gave a presentation on Swinging.
Finally, since CF is preempted by muscle in Hitting, then I personally consider it not only unused, but nonexistent as well.
