I don't understand "the fuzz" here properly, I think. I do a LOT of importing from different sources (Poser, Xfrog, Onyxtree etc.) and never think of scaling until I have the object inside Vue. Then I scale it manually to the wanted size (using the "lock XYZ" option, of course). I also have a selfmade "metric bars" object that I sometimes use for correct scaling of e.g. an imported house, a doorway should be about 2 m tall (give or take for the presumed age of the house). A similar object is available for free at C3D, "Measuring Stick" I think it's called.
