Isn't that a judgement rather than a test Sam?

x:y is good, anything less is bad?

It is one of many metrics that could be used to form a judgement (albeit a subjective one more suited to an 'informal' test like an acid test).

What's the pass fail test?

If an in-spec action results in unjustified out-of-spec directives you fail (unless the correct in-spec directives are also present).
