Even more convincing is the book itself.

From 9-0 in Chapter Nine (Three Zones):

Zone #3 is defined as Ball Control

"And any Hinge Action is Ball Control (Zone #3)."

From 2-B Trajectory Control:

"Clubface Loft (2-C-1) and Hinge Action (2-D) determine altitude and backspin and are the basic elements of Ball Control. Also study 9-3." [Note: 9-3 is Zone #3).

From 7-10 Hinge Actions:

Subtitle is "Ball Behavior"

Again from 9-0: Zone #3 is defined using three interchangeable terms. One of these is "Hands". In fact, the subtitle under the title Zone #3 in 9-3 is The "Hands" Lane. Given these facts, it's tough to see any other place for Hinge Action when you read this opening sentence in 7-10:

"Hinge Actions describe and control the manipulation of the Hands through the Impact Interval."

From 10-10 Hinge Actions (Hinging):

Subtitle is Ball Control.

Still again from 9-0:

Another interchangeable term used to define Zone #3 is "Direction". With this in mind, consider 2-G Hinge Motion:

"Direction Control (2-D) means Clubface alignment control. [The two Clubface] motions actually duplicate the three possible hinge mountings: horizontal, vertical and angled . . . "

The above references are merely the tip of the iceberg. Quite a number of additional conflicts exist -- either specifically stated or implied in the various chapters -- when Hinge Action Component is moved arbitrarily from Zone 3 (Ball Control) to Zone #2 (Club Control) [Note: the listed interchangeable terms for Zone #2 are Arms, Force and Power.] Not exactly the "finesse basis" mandate for Zone #3 activities.]

In a prior post (see #5 above), I provided the only rationale for including Hinge Action as a Zone #2 Component. If one accepts that rationale -- I personally do not -- I think we can all agree that substantial editorial work is required to put the 7th edition right.

An immediate and far simpler solution is to take a pen, go to 9-2 and cross out Component #10. Then, go to 9-3 and add it in.

Voila . . . No problem!

But Hinge Action when executed correctly influences distance = Power. Take the extremes of Horizontal hinge action versus Vertical. Huge distance/power difference.

I believe at this point Joe Daniels would have to provide details on errors between the 7th edition manuscript and the actual printed copy of the 7th edition. Unless someone else has a copy of the 7th edition manuscript.
