Oh dear, is there really a majority against the idea of a standardised Poser system of measurement?
Seems to me it already exists (In Poser 7 anyway) - no real mystery about how it works. 

I'm not really an empiracle nut or anything, just that in my line of business (commercial art) if the clent asks for a 100cm wide canvas and I supply one at 105cm, the frame generally tends not to fit. 
You can see how a head or a foot gets easily oversized in Poser, not to say that some RW people don't have very large body parts.
