I've been wondering the same thing and I'm guessing it varies somewhat from car to car and only something like a Scangauge or vacuum gauge can give you the real answer. When I'm on the hilly roads near my house with not a lot of other people around I'll build up an extra 10 or 20mph going down hill and bleed it off on the way back up the other one. But what happens if you get stuck at a stop light at the bottom of a hill? I dunno, time, and some equipment will eventually give me the answer.
