Not individually, but in combination. DW by itself doesn't tell us, 
although we know friction to be contained within. Same thing for UW. 
Their spread is the indicator, as you correctly point out.

The same way you do, with static UW/DW comparisons.

It's a friction problem if (DW-UW)/2 is out of bounds (guidelines of 
your choice). It's a mass problem if (DW+UW)/2 is out of bounds 
(again, your favorite guidelines). (DW+UW)/2 is the formula for BW. 
Once we begin working with BW, friction has been stripped out of our 
measurements. Not that friction isn't there to be dealt with. 
However, now measuring with BW, we no longer have the muddy mix of 
friction and mass which we had to put up with DW and UW. Friction is 
a separate matter from mass, and shouldn't be present to confuse our 
exploration how mass and leverage play out in this action.
