I did all the real world mileage testing years ago. If fact I'll bet you are using some of my info when looking into tranmission gearing options.

Why would the downshifts kill the gains? To the average driver, maybe, but to an ecomodder who knows how to handle hills? I am not sure I agree with this. For example, if the ecomodder is driving with load and already knows how to drive up hills to save fuel, I think in the end the VX/CX geared transmissions would still come out ahead in mileage because of the lower rpm benefit.
Do you have some of this real world mileage testing for us to look at? It'd be great to see.
