Rlafoone’s explanation is accurate. Generally speaking a higher bounce angle raises the vertical cg which can negatively effect the playability. The front to back sole radius plays a roll as well. You have to have the right amount of bounce and proper sole radius front to back and we would never reduce a bounce from what is proper just to lower the vertical cg. However, I have started to see some models with a lot of bounce on a #6 iron (for reasons I don’t understand), and it does negatively effect the vertical cg.

just a comment as Britt will have a more specific answer.
MPF is a mathematical formula, so all things being equal as you mentioned, would indicate that bounce would have no effect on the MPF.
On the other hand, if you would increase or decrease bounce, that may affect vcog, moi or rcog, etc. which of course would change the mpf (but all things aren’t equal then).
the following link shows how MPF is determined for iron heads..
