Here is some real disturbance,
So he says CF doesn't produce any swing speed, but does cause the wrist to uncock, which does produce swing speed!

If you prefer to be confused I can't help you.

Even more disturbing is the fact that he ignored my question about Hitting and gave a presentation on Swinging.

No I didn't. Read the last sentence one more time, please...

Finally, since CF is preempted by muscle in Hitting, then I personally consider it not only unused, but nonexistent as well.

Then what causes the club head to move along a curved path from top to finish? Feel free to invent a new physics and explain to the masses.
