"... Hinge Action is inseparable from Angular Motion..."
In my opinion, the quote above is the rationale -- the only rationale -- behind Hinge Action's new home in Zone #2.
In other words, Hinge Action is generated automatically by the physics of Angular Motion (2-K) -- Horizontal Hinge Action by the Throw-Out of Centrifugal Force and Angled Hinge Action by the Drive-Out of Muscular Thrust. Vertical Hinge Action is the byproduct of neither and hence is always a deliberate, mechanical manipulation.
Thus, Hinge Action executed by the Flat Left Wrist provides only a veneer control that "individualizes" Angular Motion's Clubhead Control into the three possible motions of the Clubface (Close only, Layback only and simultaneous Close and Layback). Which, also in my opinion, is why Hinge Action was a Zone #3 Component in the prior six editions: Zone #3 is all about "Clubface Control" -- "Accuracy" and "Direction" -- and is "mostly 'finesse' control" (9-2). Zone #2 is "Clubhead Control (Power)" and its "Power Components" (9-2).
So, this 'sea change' was a bold step, one that impacted many areas of the book. Its 'as is' inclusion in the seventh edition has now introduced many inconsistencies throughout the text that could have been -- and should have been -- resolved prior to publication. This is not 'Monday morning quarterbacking': It was one of the three primary concerns I voiced last winter http://www.lynnblakegolf.com/forum/s...1962#post21962. In addition to the integrating actions mentioned in that post, considerable conceptual and textual changes also are required in Chapter Nine (The Three Zones).
A lot of good thoughts here:
Leo, absolutely a big change- and nice job questioning the reasons behind it- it deserves that kind of questioning.
I also think that Lynn was correct in explaining why the change was made- and I do think that Homer was telling you the rationale for changing it as quoted.
You might think of it like this- as noted in the 6th edition 2-G. The Geometry of hinging is clubface control- The Physics of Hinging is that Hinge Action is the result of the turning torso or orbiting arms. So he's given Physics the nod over the Geometry in regards to it's categorization in Zone#2 as opposed to the 6th edition in Zone #3. Why?
It's been 24 years since I learned of the coming change of Hinge Action from Zone#3 to #2. And I had the feeling of - "What - how could he do that!!!"- because it does really create a mental shuffle for you and everything that you've learned. I asked "Why would he do that?" And the answer that I got was "You see- everybody thinks that hinge action is something you do with your hands- and IT'S NOT!" Hence, the categorization change to move it into a category that better categorizes the component in relation to the procedural nature of the movement.
As far as the integration of concepts in the book for clarity- that's been a problem from day one. And as Lynn points out - continues to be a major flaw that doesn't help anyone. Woulda, Coulda, Shoulda in the 7th edition, but there was no way- that was going to be Mr. Kelley's 7th edition and no one elses. Those changes are needed but would have to be in the 8th edition- and if the 7th took about 24 years to publish then I guess the 8th could take over 100 years to publish.

Lynn, somehow someway I get held responsible for your next adventure- But WE love video- So bring it on!

I do agree with you.

There has been some time between posts on this thread so forgive my tardiness in entering the debate. Something that has struck me very interesting about the 7th edition is where Homer makes references to a nexus between clubhead and cluface control. In 6-F-1 Right Timing is presented as not just clubhead but also clubface control, Rhythm producing maximum compression. For me, this cured my apprehensions about the implications to the 3 functions mentioned earlier in this debate...
