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.
