Newbie: Relative size

I've come to another stop in my reading of Cascading Style Sheets.

In the book the authors compare relative sizes to absolute. With
absolute one may specify a two step increment in one go (P: font-size:
medium; -> P: font-size: x-large;). As I understand it this is not
possible with relative size, where the increment is always one step a
time. Am I wrong?
