New bests

Odometer: 4672.3
Tank Mileage: 634.5
Gallons Added: 16.157
Long-Term Average: 39.4
Short-Term Average: 39.4
Calculated Average: 39.3

I miscalculated my route to the Green Grand Prix and ended up driving beyond "E". I now know that there is an audio warning at zero in addition to the already discovered warnings at 50, 25, and 10 "miles to E".

I set new records in miles driven on a tank, gallons added during a fill-up, and calculated MPG for the tank.

I reset the Short-Term Average as part of the Green Grand Prix Fuel Economy Run. More on this later, but I did get 46.6 mpg for best in my class (and there was at least one other car, a Camry Hybrid, in my class).
