Looking for clarification on Sustaining the Line of Compression. Assuming that the sweet spot is moving on an inclined plane during the impact interval, and the cluface is square to that plane at separation, what factors will provide maximum compression or compression leakage? Assume contact on sweet spot at impact and same clubhead speed at separation.
I admit I'm not sure if this has been addressed but why would we assume the same club head speed at separation? because this is not possible... Regardless of your assumptions to try and eliminate the variables, The factors that will provide maximum compression are....
A. Hinge action, a closing only club face (dual horizontal) will provide maximum compression whereas as vertical and angled will produce lay back therefore diverting the force losing compression comparatively
B. In order to sustain the line of compression the original contact point of face and ball must remain in contact through the entire impact interval ( which relates to hinge action) this is possible only if the motion or arc is uniform, Therefore there must be a perfectly centered action.
C. Any deceleration of the club unrelated to the slowing effect of two objects colliding. Such as bending the left wrist ( law of the flail) or any other mechanical inefficiency regardless of whether the sweetspot was hit or not will change the compression and separation speed
In other words... Hit that ball on the sweet spot with maximum separation speed by executing a horizontal hinge with a flat left wrist and a centered action

Please explain your reasoning. Do you mean to say that it implies that it rotates around the hosel because the handle of the baseball bat is at one end? Why does attaching a shaft to a little bat imply the face is rotating around the hosel? Does the little bat not also have a longitudinal center attached to a shaft? of course it does... If the little bat is attached to the shaft through the sweet spot then it would still be rotating around the sweetspot it's just that the hosel and sweetspot are in line
