HH is automatic in an uninhibited swing but AH and VH do require manual intervention on our behalf.
Horizontal Hinging is indeed the automatic result of the Swinger's Centrifugal Force Throw-Out Action. Thus, Angled Hinging requires the Swinger's "manual intervention."
Similarly, Angled Hinging is the automatic result of the Hitter's Muscular Thrust Drive-Out Action. And Horizontal Hinging requires the Hitter's manual intervention.
Vertical Hinging -- the Clubface staying Square to the Line in Layback-only mode -- is the natural byproduct of neither Swinging nor Hitting. As such, it is always a deliberate, mechanical manipulation.
This thread is getting a bit off topic, and my reply above didn't help matters. Questions unrelated to Book Errors should be asked and answered, but in other Forums. Let's stay on track.
