you generally want to do the opposite. you get a bigger percentage bump in speed by putting in more power when things are hard (headwind, uphill). when going fast downhill, you have to work much harder to go ever so slightly faster.

think of an extreme case: 15% hill going up and 15% going down. makes sense to work harder going up, as you will spin out going down no matter what. this still applies to less steep hills/rollers.

the reason i asked about the hills is that you are using a 404. there are faster wheels for non-hilly courses. you could gain some speed there.
