Well, if he is making millions of parts then there isn't an issue?
one of my product lines measures things in ppb. because we really are looking at billions. so I guess if I were measureing or making trillions I'd use ppt

It's not just the idea of PPM that's bothersome; it's the idea that because someone made 1000 of something and there were only 2 bad ones, that that proportion can rationally be projected out into infinity.
