I think I can take the blame for the DW confusion. I knew, when I wrote the Ops Manual, that the only suspension-type adjustments that we were making in ITR were the live axle RWD deduct, and the front-strut FWD deduct. I think maybe I just didn't get it written down right and during the review process, I didn't notice (and I guess no one else did either!)

I think if you review the weights, you'll find that those two adjustments are the only two used.
