If your going to drive with load, your going to be varying your speed considerably. And if your going to coast down hill, well, your now your just doing P&G. And P&G on a level road will always get you better mpg than a steady cruise, with the exception of leanburn.

Oops, bad math on my part. I still like hills because a hill that is 15 mpg up and 150 mpg down describes a worst case scenario hill. As you show it is still better than the lower end of flat ground cruising. If a hill is steep enough to be 15mpg the way back down will keep me over 65 (at .26gph idle or on DFCO)
