Right AA it should have been as high as possible at constant speeds. There is some evidence that it may actually be slightly better to do mini P&Gs when there are slight hills.

I experienced that with my CVT insight and it seems to hold true for my CVT Altima. Slight grades seem to make little to no difference in fuel mileage (read from instantaneous gauge) while the same downhill sections will see mileage jump to 60 Max gauge reading).

I did a 40 mile stretch of road today at 55 MPh and got 41 MPG in the Altima.

Definitely try to keep the readings as steady as possible if the terrain is flat, but even in hills of very shallow grade you might try to mini P&G and actually achieve better mileage than on flat ground.

Again very shallow grades probably less than 2%.
