Morning, Lewis. I use the trip B ALL the time - to see what I get in the city; on the highway; up a few hills; down some hills; with people in the car; into the wind; against the wind. Usefull? I don't know. I think so, but it's just more game factor, I guess.

One 11 mile stretch with an overall drop of ~400 feet and into town with a first stop at a traffic light, I received 74 mpg! The tank finished at ~36, but fun nonetheless.
