I still don't think we have defined:

A. All the functions of the pivot
B. The Components that make up the pivot
C. Sequence of Movement in the Pivot
D. Relation of Pivot to Plane Angle
E. Relation of Pivot to Plane Line
F. Relation of Pivot to Hand Path
G. Relation of Pivot to Clubface
E. Relation of Pivot do Low Point

Does that get us back to the task at hand?

So let's start with Function

1. Deliver the Power Package to the desired Impact Hand Location with the corresponding amount of Shaft Lean
2. Develop Angular Momentum and/or Support of Muscular Thrust
3. Allow the club to satisfy desired Plane Line/Angle requirements via the amount of Axis Tilt
4. Produce the desired Hinge Action and comply with Grip Type Requirements
5. Produce the necessary amount of Pivot Lag (for full power shots from the ground up i.e. Swinging from the Feet) Transfer momentum from "joint segments"
6. Balance the Machine
7. Have a Center that produces a consistent Low Point and Angle of Attack

That's my 5 minute stab at it . . . in no particular order.

B. Components:

One way to analyze the pivot summarizes the component parts as:

Feet
Hips
Shoulders
Power package
Club

Of course there is soft tissue and other variables in between these points but these in particular seem to be a good starting point.

C. An efficient pivot occurs indeed from the groud up, with a kinetic link sequence of the segments listed in B above beginning with the ground and ending in the club compressing the ball through the impact interval.

I am still not sure how you are going to tie this to alignment, though, Buck.
