I'm pretty sure it means elevation as a a per cent of distance traveled.
That is, if the change in elevation is 7 feet over a distance driven of 100
feet, then it's a 7% grade.
I'm not sure if it's measured as per cent of the actual distance traveled
(measured on the hypotenuse), or of the horizontal, or level, distance
(slightly less than the odometer distance).
