Daniel and I have a recurring argument about "less" versus "fewer." Unlike most of the rest of the world, I care about that distinction. Daniel thinks I'm being pedantic. (We do have other grammatical arguments where the roles are reversed.) Daniel likes to quiz me, offering grey areas that involve decimals to try and catch me up. "Is 1.3 gallons of gas less or fewer than 1.7?" That kind of thing. I particularly liked his most recent attempt. Which I aced, by the way.

Is 4mph less or fewer than 10mph?

The answer is, of course, slower.
