he!  i think i did.  i can be scatterbrained, too.  and here's a trick a non-Blender user might not know: i make sure to scale by the cursor rather than by the midpoint or anything, and have the cursor at 0, 0, 0.  also, i keep my exported .obj singular, but let my scaled duplicates pile up.  that way if i want to go back a few versions, i just scale one of the tiny duplicates up.
