@johnzajac @EricLawton @bonaventuresoft What I'm saying might reduce to "don't call that efficiency, we need another word". ("Effectiveness")
Because efficiency-the-word is pretty strictly the cost-efficiency zero-margin meaning and fighting with the mammonites for it is a lot more work than I think we have to do.
Jane Jacob's guardian and trader syndromes ("what can I get for this?" versus "what's the most I can turn this into?") come to mind here.
