Good job SVOboy
I'm with McTimson, % over EPA. You could make those in a table right under the mpg's (2 rows - % & mpg, 3 columns - gas, diesel & electric).
SVO - Will this be a constantly changing list as people update their fuel logs? That would be cool if it auto updated. I liked Piwoslaw's idea so you could sort the 3 types of cars (gas, hybrid, electric) my mpg and % over EPA.
