That 'CF force' arrow is not random. It is precisely parallel to (2-K #1 and #3) -- or in line with (2-K #2) -- the left arm.

Out of curiosity, what is your explanation of the dynamic?

BTW, give it your best shot, because this is going to be an extremely short-lived interaction.

You mean dynamics of the release? What causes it if not non-existent "CF"?

That explanation be here: http://nmgolfscience.tripod.com/release.htm

Requires a high school physics level of understanding... peruse at your leisure or don't... It does not matter to me and I won't be offended if you opt out. I'll be back in about a week .... business calls.
