I got to thinking more about it arcosine and I think you are right. If I climb that hill in the morning, I can convert most of that potential energy back into kinetic with minimal braking along the rest of the route. On the way home, I'm engine braking and disc braking all the way down that hill to the stop sign.

Peaking the hills at speed is key to not braking at the bottom - hopefully not too many people will get angry at me for taking part of the route at a slower pace.

Climbing the hill will allow me to spend time at my best BSFC too based on what I can find on the topic. Anybody have a chart for the 2002 GM 3800 engine?
