Great info. I'll play with it some more once I've got my ultragauge installed and calibrated correctly... maybe I'll see some effects in the end.

I know that on my most hilly trip, which I take a few times a year, I do see a difference if I DWL up the hills and coast neutral down the hills rather than maintaining a target speed... so I'm not saying that techniques like P&G are snake oil, I just have trouble seeing how they can be as effective as some folks say they are unless your transition points make use of terrain so you can convert potential energy into kinetic...

The UG should also help me determine (and monitor) the optimal throttle position for efficiency for those tests as well.
