Really? What goes from 7-5 or 8-4?
The left arm.

If it is the clubhead- AM would be 9-3 since the arms go to parallel.
IN the Golfing Machine the Right forearm level to the ground is the measurement for acquired motion.

And going to any of these clockface numbers can be done without traveling on an Incline Plane- and what does that get you?

Mike,
I assumed via his question that he was looking for a non-golfing machine answer- since he liked the left arm and clock analogy for adjusting swing length. I just gave him my own quickie answer- making my own "Golfing Machine Translation". Regarding "what does that get you"- you'd have to ask him. I assumed he was just taking a three dimensional movement (inclined plane motion)- and converting it into a 2 dimensional measuring system (the face of the clock) for determining length of swing in a mirror. In a similar sense you do the same thing with angle of approach measurements etc.- taking a three dimenisonal movement and looking at it in a 2 dimensional format.

I did like your previous post- in that you said you should monitor the hands and not the clubhead. Probably would have been a good idea for Homer to measure the basic motion length via hand motion and not clubhead motion so that the focus is in the right place.
