Hehe, yeah there's some terms that just are linguistically unintuitive.

"Skill floor" is another one. People generally interpret that one as "must be at least this tall to ride", but it actually means "amount of effort that translates to result". Something that has a high skill floor (if you write "high floor of skill" it makes more sense) means that with very little input you can gain a lot of result. Whereas a low skill floor means something behaves more linearly, where very little input only gains very little result.

Even though its just the antonym, "skill ceiling" is much more intuitive in that regard.
