"sweet spot" physics- where are you?

Throwaway.

Absolutely! More common than many would think.

It's rampant - moving the hands independently of the pivot, or as Ben Doyle says, "adding".

Now, lets displace the Center Of Mass of the club head from the axis of the shaft. 2 additional pieces of Physics are introduced. Toe up/down and torque.
1. with the COG thailing and on the plane we have toe up when accelerating and toe down when decelerating.
2. as the COG leaves the plane of the shaft we have toe down equated to radial force and torque- laging (tending to lay the COM back-open if above the shaft plane) when accelerating and leading(tending to have the COM pass the shaft- close of above the shaft plane- Roll under if COM is below the shaft plane (Driver as example)) when decelerating.

All making the dynamics a computer learned event.
ie. learn a motion then let the computer learn how to hit the ball.

I include some shaft dynamics data as illustration.

Interesting stuff!

PS.
This data shows that the pro's have a forward bend in their shaft at impact- Throwaway- I think so, Also a loss of effective Club Head mass. But lets hold that analysis for another post.

Had the sweetspot passed the hands though?

Had the sweetspot passed the hands though?

Your question requires more information on dynamics.
If you are questioning forward lean- maybe, maybe not but forward lean is not the critical factor.
If you are questioning COM vs. hands on grip, the answer is yes. The shaft will be bent forward- lag gone, effective mass decreased. Mass is developed from the ground or the last lagging component closest to the clubhead.

ps. Quick reply Huh?- just happened to be here editing.
