Here are a couple of points I have wondered about that will be significant in the MPG contest.
1. I've got carbs. If I stay in gear as I release my foot from the gas pedal, does it pull more gas through the jets than at idle? I'm thinking yes, but...
2. Does it make more sense to slowly accelerate to traffic speed, or give it more throttle for a shorter period? My guess is that a lighter vehicle might benefit more from going to cruising mode as quickly as possible. I'm thinking that there must be a balance somewhere between mass and rate of speed increase and WOT consumption vs. cruising consumption.

Anybody wanna speculate?
