"...The averaging of the two runs is just to eliminate any effect of elevation change on the test runs...."

Oh. Fair enough. :)
Still need to be avoiding a route with too much elevation changes as while those offset each other significantly better than tail and head-winds do they still don't quite balance/average out.

Even with head/tail winds, averaging a run in both directions will give you a more accurate measure of energy consumed than just using one or the other

If you were driving north/south with a 10 mph north wind, averaging the two runs should give you something pretty close to the energy you would use on a calm day I would think

Thought I'd link this thread to the iMiEV Range Chart from jumpjack which shows the (theoretical) decrease in range at very low speeds due to all the fixed loads powering the system. Without climate controls, the speed is about 12.5mph (20km/h). Has anyone taken any CaniOn data which might corroborate this?
