Hinge vs. Swivel

[Etzwane]

But did you know, that the Clubface, when using Hinging, Closes at a much Slower Rate than with a Swivel? This is one of the benefits of Hinging.

Is that the main benefit of Hinging ? Clubface control because of the lower rate of closure ? Was it identified before Homer named it, or at least taught somehow ?

The benefit is Clubface Control. "Control" includes "Clubface Alignment" at Impact, the "Clubface motion" (Closing Only, Closing with Layback, Layback Only) through the Impact Interval and the "Rate of Closing and/or Layback".

It was identified by Homer Kelley. The "Right Forearm Angle of Approach" traveling the "Pulley" determines the Closing Ratio. Another way is "Swiveling".

The Low Rate of Closing is an Important benefit that Hinging Provides. It's important because the amount of Rotation of the Line of Compression during Impact/Separation is only about .37 degrees. Swiveling through Impact has erratic Ball Flight because it isn't possible to control the Closing Rate.
