OB.

Interesting point.

If I remember correctly, the more #3 accumulator the more head travel for any forearm rotation. Am I saying that right?

So, for horizontal hinging which employs more #3 the club head is accelerating more then with vertical hinging?

Am I correct so far?

Would that mean that if I can accelerate the club more over a shorter time frame that I get more umf than going at a constant speed?

I hope I haven't just confused myself. Is this what you meant with your car analogy?

The car analogy was a little different. It was more about assuming they ( beatle and 911) are going the same speed and then deducing they are equally powerful. They're different cars. For any given hand speed you get more clubhead speed with Horizontal.

The #3 angle is set when you grip the club really. So Horizontal and Vertical have the same amount of #3 angle. No difference there. But Horizontal (in simple terms) has the left arm rolling. Angled has it not rolling. Vertical has it reverse rolling. So Horizontal's clubhead travel is greater (than the other hinge actions) for any associated distance the hands travel . Vertical a reverse roll has the clubhead traveling less. Angled has zero cubhead hinge " travel".

Did i say that correctly ? Now Im getting confused.

Try this....hold out your left arm and hand as if to shake someones hand , now drop it down on the inclined plane. Now grip an imaginary golf club and take your hand back and forth a foot or so. No left arm roll equals Angled. Roll equals Horizontal , reverse roll is Vertical. Imagine how that change in roll changes the distance the head travels though your hands are only going back and forth a foot or so. Now adopt a putting grip with the club running up the life line.... hinging has zero influence clubhead speed, "zero travel" via a "zeroed #3 accumulator, just different clubface rotation.


So the hinge action employed influences clubhead speed and the rate of clubface closing and layback.

In regard to closing , the clubface is in the process of continuously closing through impact however brief that may be. The face will be more closed at separation than at impact unless impact is 0 seconds long. Same deal with layback, the clubface will be more lofted at separation. So the question is does this influence ball behaviour, compression? My chips and pitches suggest it does.
