This may just be a P7 thing(?), but the Poser reference manual claims that 1 PNU = 8.6 feet - NOT 1PNU = 1 foot. This may have changed, I don't know.

With Poser's interface units set to PNU:
I take a box primitive, scale it to 0 in the y axis and translate it to 1. 
I then switch units to Feet and the y trans of my squashed box prim does indeed read 8.6(feet).

This does make Geeps scales incorrect, at least to Poser(7) internal unit measurements. It also makes most figures I've measured so far to be well above average height for realistic humans, although given the mediums leaning toward the 'ideal' and 'heroic' themes perhaps this is understandable.

Am I way off with my theory here? It would seem to be a good thing to have some kind of accepted practice when it comes to scaling.
