Sure, but what did that 40 hp lathe cost? The cu-in/min is very
impressive, but what's the cu-in/min/$? It's the "/$" that's the great
equalizer. Although I do suspect that there's an economy-of-scale thing
here, where bigger is cheaper. So the vol/time/cost number is most
useful for comparing like-scale tools. E.g., a home shop lathe to a
home shop drill press, etc.
