I believe the "sweet spot" is aligned to the ball at fix to adjust your computer and thats IT. What are, if any, the Physics of the sweet spot? Like to hear an engineering - mechanical dynamics- reasoning on the "sweet spot".
COG of the club head. The head being "heavier" than the shaft and the heaviest part of the shaft being in the grip. Suspension of the club from trhe butt of the grip will likely place the COG of the club head directly "below" the point of suspension. EVEN IF he shaft is bent like a "7" and hung on the edge of a table with the grip pointed NORTH- ( that would be southern cross for that part of the world where the blood rushes to your head). So the sweer spot is aimed by the computer??? Unless OTHER phisics can be added??? This is a valuable discussion due to HK emphasis on Sweet Spot I believe. Yes?, No?, Maybe?
Seriously:
We must add/change our vocabulary.
COG is a very specific and limited term- relates to weight- a mass within a uniform force, gravity. I would like to hear the physics discussed using MASS, ACCELERATION and FORCE, CENTROID com and MOMENT. (basic F=MA) because therein lies the physics of the golf club/swing.

Reason: Add clarity
Interesting HB but according to Homer isn't it the LCOG? From the lowest point of contact on the aft of the shaft to whatever it plumb bobs? The sweetspot being a point without dimension and moveable depending upon where the lowest point of contact is (gripping up or down etc. )
The Golf Club has various balance points and the Clubhead also has a balance point (COG). The #3 PP senses and directs the Clubhead COG.
The Clubhead COG has an Orbital Path. The Ball has a COG.
It's important to note that the COG of the Ball always intersects the COG Orbit of the Clubhead unless you're hitting a specialty shot (i.e. Driver off the deck or sand shot).
Please note that the Impact and Separation points are for illustrative purposes only. Although Impact and separation points may be the same on the Horizontal Plane, it isn't necessary (or even possible, except during Vertical Hinging) on the Vertical Plane.

MY BOLD of quote;
Senses NO, Directs YES;
Lacking demonstrable knowledge of the Mechanical Dynamics. I start at the place that the "sweet spot" is a learned POSITION and is located by YOUR COMPUTER in a mechanical manner. Now, IF mechanical dynamics (physics) of the "sweet spot" (lets use Centroid or center of mass) can demonstrate a "sensable" effect we have something new. I have not found that effect.
