I think to get the hypermiling star in Greenhybrid's database you have to average over EPA for 3000 miles.
I snipped this from GH Database page:
Hypermiler! The driver of this car has achieved "hypermiler" status. To qualify, a car must have higher fuel economy than EPA estimates over more than 3,000 miles. The EPA city/highway figures are weighted for each car. If no percentages are specified, 55/45% is default.
Need fewer troops to support.
Drive a hybrid.
Best tank 71.65 MPG.
Before this car I spent two years learning hypermiling on my 2004 HCH1.
