Of course that begs the question, "What is the mpg score and how is it calculated?"

As well as other detail questions such as "Are there specific fillup procedures before or after the competition?"

Not knowing how the car will be topped up for scoring after driving the loop, I'm inclined (for both fills) to fill till it pools at the top of the filler neck. Normally I stop at the first clickoff but for this relatively small amount of fuel I think it may be more precise to bring it absolutely to the top both times.
