More energy expended for a shorter duration though. What you have stated does not appear to be in conflict with my theory.
I acknowledge that there are practical limits to my theory, such as running an engine outside of the efficient range, and wind resistance. However, I don't see any evidence to support the theory that going as slow as possible up a hill is best.

Thanks for throwing out the tip. I always buy manual transmissions and never run a cruise control up a hill. Generally I build up some speed before beginning a hill climb, and maintain that speed to the top, depending on what the conditions are like on the other side. For example, I will coast towards the top of a hill and let my speed bleed off if I know the back side will carry me back up to speed.
