Homer Kelley clearly differentiated Hinge Action during the Impact Interval from Swivel Action into and out of the Impact Interval. Again, Hinge Action -- Horizontal, Vertical or Angled -- is not a 'true' Rotation of the Hands. Swivel Action is. Hence, at no time should a Swivel Action replace a Hinge Action during Impact.

This is true even when using a Snap Release, during which the Impact Interval is so short -- almost instantaneous -- as to 'Feel' like a Swivel. Remember, even if the Hinge Action lasts only a couple of inches, that's all you need.
