Thank You BerntR. Your explanation is clear. I can understand how many Golfers, using Pivot Controlled Hands on the Elbow Plane can "Feel" like that's occurring, although video demonstrates otherwise.

Thanks again.

Yep,

It probably would take a constant ratio sweep release that starts from the top to keeep the MOI center on plane with a Haney plane. If there's som snappin' going on it has to be a true plane shift. Down and out - as Ian Woosnam used to say (or something like that).
