That was my point. And no, I don't complain, because I get an energy bill. Although they do charge me extra for peak power and average power factor as well.Well, to be factual, acceleration and decelaration are the changes in speed. Speed is actual and accel/decal derivative. I am curious if you complain to the Power Company when your 'Power Bill' arrives. Lets face it, this conversation seems a little silly and tends to lead to forum combat. It is really not a big deal for a game.
