For the lack of better term. ( If anyone could introduce me to one, surely there is a term for it ) If we use the Normal distribution or empirical rule, we would get a top end number of ~83.9%, 97.5%, 99.6% of things are crap depending on your definition of crap.

And if your taste just sit between the 83.9 and 97.5 number. It turns out to be just about 90%.
