One thing to remember is that we vary in our ability to cope. There are all sorts of little tricks, and then some of us will cheerfully attack a Poser datafile with a text editor. Being aware of the scale variation is one of those little tricks, as is the stuff about body proportions. And working through geeps tutorials will expose you to a lot. Yeah, I know about this metric/Imperial stuff. I'm old enough a European to have tangled with both: 22 yards to a chain, 10 chains to a furlong, 8 furlongs to a mile. And 10 square chains to an acre. And there's always the firkin-furlong-fortnight system. The current official Poser scale is stupid. It isn't a round figure in either system; not in inches, feet, or metres. Not 100 inches. Not 8 feet. Not 2.5 metres. Stupid. People don't often make props in Poser, so Poser's built-in conversion isn't much use.
