With your comment about the longer gears and using less fuel. If the engine is turning more rpm, there fore in a more efficient rpm range, but using the same overall fuel per mile. Shorter squirts, but more of them. The advantage is gained when on hilly terrain (Ohio is not flat!) I'm not lugging or having to downshift for the hills, aka "transient response" as some of the Honda Engineers called it.
Now if there was a 7.5 mile oval that could have been used for near perfect test conditions....like right next to a major automobile production facility....
