Jeff, and why not ? The clubhead and the hand are so relatively distal things from each other that it does not change practically anything in the hands relation to the clubhead. If we assume that the club rotates around an imaginary axis coming through its CoG (assuming it comes through sweetspot as well) it is natural to suspect that the sweetspot remains on the same inclined plane all the time forcing the shaft and the hosel change its original plane to a slightly higher one. It is very logical for me.

Here is photo of Tiger Woods and Adam Scott in mid-downswing.



Note that the back of their flat left wrist/hand is against the inclined plane. Note that their clubshaft hosel and clubface sweetspot is also along the same plane.

Now, you stated "why not" - which means that you can imagine that the cluface sweetspot can be on a different plane than the back of the left wrist/hand at this time point.

To me, that means that you really do not understand the relationship between left hand movements and the clubface. If the clubface was not on the same plane as the back of the left wrist/hand at this time point, then the left wrist/hand cannot be flat - it would have to be bent. In my mental universe, the left wrist/hand must always remain flat throughout the entire swing. If the left wrist/hand always remains flat and the clubface is always exactly in a straight line relationship with the back of the flat left wrist/hand, then the clubface must always rotate at the same rpm as the back of the flat left wrist/hand.

You wrote-: "Homer defines "the" plane as the hands (pressure points) and sweetspot. Not shaft. You may not understand the relevance of the physics, in fact, you clearly don't (nor do you understand the bold section above)."

I clearly do understand that point. The orbiting sweetspot travels on the imaginary sweetspot plane and it is directed by PP#3 acting through the sweetspot of the clubhead. A golfer doesn't have to ever think of the clubshaft in this scenario because the only important relationship is between PP#3 and the sweetspot. During the downswing, PP#3 aims/directs the sweetspot at the base of the sweetspot plane. The ball sits on the base of the sweetspot plane, so the sweetspot is precisely directed towards the ball at its ground location on the ball-target line (which is the base of the sweetspot's inclined plane).

However, I personally think that you need to better understand the relationship between the sweetspot plane and the clubshaft plane if you want to efficiently swing Yodas Luke's big club.

Jeff, you are right, I don't understand what trigonometric influence on wrist flatness can make an inch of distance between the hosel and the sweetspot when comparing to 40 inches distance between the wrist and the clubhead.
Enlight me, please, but I still think you are missing the big picture while concentrating on not important details that usually darken this picture.

Cheers
