High and low are quantifiable risks. Starliner risk is a divide by zero error NaN instead of a value. . . . as we know, there are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns—the ones we don't know we don't know. https://en.wikipedia.org/wiki/There_are_unknown_unknowns https://en.wikipedia.org/wiki/There_are_unknown_unknowns
