hinge actions and timing

[HungryBear]

Where I struggle most in all of this is to see where roll & swivel ends and where hinge action begins.

I have found No need for swivel before follow-through an little roll only what is needed to get from flat onplane to vertical and that is completed before the shaft is level and parallel to plane line. I have the face "square" for as early and long as practical. BUT, thats just me because we all have seen many other ways to do it.
On the surface that may not sound correct. But to me, the motion is circular on a flat angled plane, movement on the surface is angular. #2 and #3 release are sequential but not seperate, thereleases will be geometric ie. sinusoidal, #2 will release "more rapidly" early and #3 will start release slowly and max after impact. Just my visualization.
