Personally, my sense of smell is my least favorite sense. Freaks me out for some reason. Then again I have OCD

The measure doesn't come from a smell test, it comes from how prolific the cellular bind sites are for the scent receptors. More of a "look at cells under a microscope and see what the receptor properties are" kind of thing and less of a guess and check by smelling stuff.

Dogs have around 300 million scent receptors, which is why they have such an acute sense of smell. We smell more scents, but less acutely.
