Good work, Ron. If only everyone could make information so accessible and entertaining... there would STILL be people complaining about it. Never mind. :-) I used to use the 1PU = 100" rule simply because it made calculation very easy for the hard of thinking - but now Curious Labs have told us what the standard is, why not use it? It makes good sense when measured against the Poser folk; and if it doesn't suit, well, everything's relative isn't it?
