[O.B.Left]

"If two players wind up at impact separation with the clubhead, face and shaft in the exact same alignments all at the same speed and hitting the ball in the same spot on the face with every other alignment matching with the only difference being that one player arrived there after a Horizontal Hinge action and other player arrived there after a Vertical Hinge Action."

Exact same alignments, same spot on club face , same speed, etc.
The ball would have the exact same compression - how could it not?? That being said it is easier to add loft using a vertial hinge but that is not relevant to the question at presented.

Hey mb.

I know that the question as posted is not the one you really want answered. Change the question if you want.......

To spell it out.........how can "the clubhead, face and shaft ....all at the same speed" happen given any # 3 angle? It cant. The butt end and the head are not traveling at the same speed for HH vs Angled vs VH. .......Its impossible.

So his question must change. Which makes things more apples vs oranges ......to my mind.

Sorta like two cars doing 60 mph....one a vw beatle in fourth gear the other a porsche.....ya they're both assumed to be going 60 but does that mean they are equally powerful in a general sense? Of course not. Does this make the Porsche's power advantage "irrelevant" .......no , of course not. HH is the Porsche in this example which relates to velocity only. Id suggest that there are other considerations to compression for HH vs VH beyond this point.
