I have a recollection that, pre-P5, it was generally accepted that 1 PNU = 96 inches. Which is 8 feet. And it's been reported upthread that D|S makes 100 units DGS come out as 96 units by its own internal conversions. So D|S must be using that old 96-inch standard. As for proportions, I suppose the best thing to do is point folks at da Vinci'sVitruvian Man. When I'm importing a mesh I use DGS. It's sitting in the middle, and doesn't look obviously wrong. I've paid for Poser models which are badly out of scale, a 50% error rather than 5%. It looks careless, but it isn't a huge problem.
