Does this sound right?

Alright, so we know that the car accelerates faster downhill. Even faster depending on the degree of the hill.

I like to hold the gas pedal( just regular pressure) downhill and by the time i am close the the top, i will only need to gas a little bit, since the speed i gained downhill pushed me up.

I tried to let off gas when going downhill, but i gained speed slowly, and the engine had to work hard from bottom of the hill, as a result the RPMs will be high.

So if i speed up down hill( the engine doesn't have to work that hard since gravity helps it gain speed with low RPMs.

So low RPMs=Higher MPG (car doesn't have to work hard climbing a hill)

What do you think?
