I think we all agree that Hinging requires Rhythm of the Primary Lever, an undisturbed Clubhead Orbit, and a Clubface Aligned to one of the three Associated Planes.
We may not all agree on Swivel. I view Clubface Rotation as a "Swivel" when the Clubface rotates with an Alignment to anything other than an Associated Plane, such as the Center of Gravity of the Clubhead, or with a True Rotation of the Hands.
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.
