This is the classic problem where people use averages as a metric, but ignore the fact that variations are not distributed evenly.

I remember looking at the economics of a clinic for our product. Someone said "let's just give them a 5% discount as on average they will break-even.

That works if you look at on average how much they make, but ignore the fact that every clinic has a different mix of insurance companies and *their own economics are all different."
