Well we have to start somewhere. When you first put your foot on the gas the acceleration comes first, then the velocity, then position. Poo-pooing the initial acceleration because you haven't moved very far yet is rather short-sighted.

Heavy industry isn't a freaking SAAS startup with an indoor playground and free beer where profit isn't expected because you're just going for a buyout. It takes many years if not decades to build out brand new physical supply chains on any meaningful scale. Yes we're just getting started, but without this metric we'd be going nowhere.
