Okay, here is another engineering geek putting in his $.02 worth. The power factor is based on momentum for two reasons: it was an easier calculation using the ballistic pendulum and (2) the forefathers of IPSC wanted to make sure that the "wimpy" 9mm would not be considered a "man's gun".

As far as changing the power factor goes, yes, I am all for it. The one problem I see is all the folks out there who shoot 45 acp. That gun is set up to shoot a heavy projectile at low velocity. I am not sure it can be downloaded to a pf around 150 or so. I do not have much experience with 45.

It was mentioned on another board that instead of lowering the power factor, we raise it instead. That way, the people who would benifit would be the folks who are shooting hot loads and choose to do so. The recoil they would have to deal with would be the price they would have to pay for scoring major.
