Advice on gas saving on small up slope?

[SpaceShot]

In my area nearly all the hills are `rolling' and very much like a roller coaster. Most hills have at least a slight downslope on the approach or 50m or more of flat.
Slightly accelerate here and up the first 25%-30% of the hill.
Then back off a touch and hold the gas light and steady. (dropping 5 - 10 Mph when reaching the crest)
Accelerate briefly over the crest and on 10% of the downslope.
Coast the rest of the way down.
Just before the flat go back to holding the gas light but steady.

It takes a fair amount of practice to do it just right. But if you cross over the same hill every day you will get it, and will do better than trying to use `cruise control'. (by your driving or with actual cruise control)

Having a Scanguage or similar Mpg readout device can really help to get your driving tuned in with your daily route.
