When I did coastdown and cruise control testing, my test track was 2km (1.25 mi), with an extra 1km at each end to turn around and adjust speed. The 2km was enough to coast from 100km/h (62.5 mph) down to about 40km/h (25 mph).

I found out that my test track had a slight slope. Very small, not enough to see, but enough to give a 20% difference between E and W runs. I wonder how much this offset my data, since on a slope the weight plays a larger role.

I know how hard it can be to find a good stretch of road, but if you have 2-3 roads to choose from, pick the one that is closest to straight. On each bend you lose some energy.
