On Forces active in the Golf Swing....

[Yoda]

I see these funny little diagrams with an arrow labeled CF appearing to cause "release"... Uh.... No... thats not the way... awe nevermind .... resistance is futile

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

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.
