Hinge Action is rhythm. Acc3 is rhythm control. Read the second paragraph of 6-B-3-0. True Throw-out action of CF aligns the clubface for Horizontal Hinging.
So where does CF end, HH begins, and how the heck can anyone divide this on the Swinger's DownStroke? A Swinger can have the 'feel' of HH being the Turn/Roll Action, so CF will sub as HH for the 'true' throw-out Swing Pattern. A Swinger CANNOT control the clubface like a Hitter. Trust in ball postion and alignments is all he or she has.
Hinge is Motion/Geometry and CF is Power/physics. Yin and Yang. No one or the other.
Does HH exist without CF? Of course. Educated Hands of a machine head can perform all hinge motions.
If you a SWINGER and prepare to execute a Hinge Action on an Incline Plane with 3-F-6- you are ahead of the game.
