Wow I never realized that I could just put my combined mileage in, not being teh same as EPA combined. I say this because most of my driving is done in a city/suburb area with lots of stop signs and traffic lights.

I don't think people are actually cheating. Why would they cheat there is nothing to win. I mean if they "cheat" they are just getting a false sense of accomplishment. Most of these decrepencies are most likely from what others are saying as the combined routes being different from another hypermiler's and some errors.
