I know when I drive (and I do about 1000 miles or more a week. I try and keep it in my power band, I get from 1500rpm to 2200 rpm (which is 80mph at the top end for interstate). And I save greatly. And to say that a fast start is a good thing, is just silly in itself, look at any car computer and see what it says when you get above 2500rpm, you start seeing great drops in fuel economy. so slow off the line and steady on the gas the whole way and you will save.
