I agree, however the test road is about 15 miles from my home, so hopefully at least for the direct drive-train, that should not be an issue starting from the similar ambient conditions with a cold car.

I have been aiming for consistency in how I test for that reason. I don't expect everything to jive with extended open-road efficiency.
