That won't prove anything. That's essentially what the writer of the PM article that started this discussion did. What's needed is a net usage result as gealii posted. What we're trying to prove is that the gas lost while coasting in neutral and regaining the momentum lost during the coast is less than the gas that would be lost trying to regain the momentum lost after coating in gear.

There is no question that coasting in gear loses less gas DURING the coast than coasting in neutral ...
