On Page 28 of the 6th edition, HK writes "Doing the above drill with Zero Accumulaor #3 (6-B-3-B) will show that then, all Lag Loading and Hinge Action have Angled Hinging Travel AND Rhythm. So--intentional use of Zero Accumulator #3 can be useful while unintentional use can be hazardous."

Could someone expand on these two sentences? I understand the different hinge actions, but I am in a fog as to what these two sentences mean.

With a number 3 accumulator- horizontal hinging has the longest arc travel of the clubhead, angled hinging less, and vertically hinging even less. That travel and the time it takes to cover that distance is the RHYTHM. Even further removed from that travel is that the lag loading and method of acceleration creates certain kinds of travel inherent in that procedure.

That said, when you have no #3 accumulator- regardless of the lag loading procedure, and regardless of the acceleration method, and regardless of the inherent hinge action in that procedure- or even if you are manually over-riding with a selected hinge action- it doesn't matter if it is horizontal hinging (normally the longest travel), angled hinging, or vertically hinging (normally the shortest travel), all of them will have the same travel with the zero #3 accumulator that the angled hinging has WITH any amount of number three accumulator.

That's fine if you understand that- but if you were unaware of it- that could be a problem because you might have other components trying to coordinate at a different Rhythm- travel time and distance covered- than the Rhythm of the #3 accumulator. Or put in a different way by Homer Kelley himself in 6-B-3-0 "The Turning Rate of the Pivot Components especially the Shoulder Turn as actuated by Hip Action (7-15) MUST be identical and synchronous with the #3 Accumulator Roll, else its Rhythm gets disrupted. or at least difficult."
