I see what you are saying about the possibility of differences, but it was my understanding that for any vehicle you are kind of taking a "smeared" number, meaning that it's an average of numbers, and is meant to get you as close as possible. I think that's what is happening on the gasoline versions also. For that matter, I think that is what happens in all vehicles with this technology, since they are not actually measuring the fuel used, they are measuring the amount of time the valves are open or the amount of air used.
