The longer the hosel, the higher and to the heel side the cg usually is, which is not good. The more offset, the higher the longer the rearward cg dimension, which is good. You can have a good rearward cg without a lot of offset and you can have a bad rearward cg location with offset. It simply depends on how the overall mass is distributed. Generally speaking, more offset will improve the rearward cg number. Shorter hosels can give designers the ability to put more mass in good places that can increase the playability. Does in it mean they all do and that all shorter hosel irons will be more playable, no. Longer C-dimensions (horizontal cg location), lower vertical cg, more rearward cg location and higher MOI are all important to the stability of the iron and thus a higher playability / MPF rating.

Hi Sean, the following is a link to determine the MPF of an iron head
http://ralphmaltby.com/method-of-determining-mpf/
in regards to the hosel length and offset, they are factors that make up the club head, so it would have an effect on the MPF formula…i.e. effect the center of gravity, both vertical and rearward (away from the face).
If you are asking about the MPF of a golf shaft, the iron head doesn’t isn’t a factor of the shaft MPF. It will effect the frequency (stiffness) of the shaft, however the hosel length and offset won’t effect the shafts MPF.
I’m sure there are others that can expand on this more than I, the above is what I understand about the Maltby formulas
