Almost Clear
 

I am trying to get an accurate understanding of goals so I can optimize my practice time..Yoda talks about the sweet spot plane as preferable according to Homer--the sweet spot is a "spot" rather than a line-therefore it can be on the turned shoulder plane while the shaft has infinite options of its plane..Is the correcd-TGM- definition of the sweet spot plane a line parallel to the shaft going through the sweet spot??I hope so--tell me its true---

precision
 

exactly what part of the grip area are we talking about??That puts the clubshaft even more upright at impact if we stay on the turned shoulder plane--seems as if the club lie angle must be jacked way up--

Pp3
 

Where PP3 touches the shaft, a line can be drawn to the sweet spot of the clubface.

A Hit Stroke Pattern would pull the sweetspot away from the ball and return it. Here,there is a defined difference between SweetSpot Plane and Club Shaft Plane throughout the stroke.

A Swing Stroke Pattern would move the SS away from the ball then align it with the club shaft plane as PP3 rotates under the shaft. At release position the SSP is now above the shaft and as the shaft rotates around the SSP returns to impact. Hitter never rotated it.

see Hand Action.

what the mind conceives the body will achieve
 

so---impact fix should have a line from the sweet spot through pp#3 through the turned shoulder plane ideally for a no plane shift motion---the line from sweet spot to pp#3 should point at or be parallel to the plane line throughout the motion---if my impression is correct I am on my way

In the backswing I think it is better to move the clubhead/sweetspot around the hands and clubshaft, not viceversa. Because in the backswing anybody cannot generate so much centrifugal to mantain the lever's center of gravity (sweetspot) in a constant angular motion (flat, 2 dimensional circular path) while applying other not on plane forces such as turning, hand motion.

You turn your hands, the clubhead moves more inward, but the hands don't move out, If the turn is made strongly.

However, in release, you can try roll the hands(a swivel at impact, just for the experiment, because hinge action gives more precision). Sweetspot always stays on plane (for example the square shoulder plane), the hands rotate/move around it. So clubshaft/left arm come to near to the ground and closer to the body.

I remember reading on a chapter that the clubshaft moves around the sweetspot. I think Homer Kelley was referring only to the downswing.
