I don't know how you would figure out how to weight it. But then again I'm not the sharpest knife in the drawer. If someone repeatedly misses the min fill or no fill in 28 days they are disqualified. I'm open to a vote on how everyone wants to proceed because really all I'm doing is trying to get better FE every day and not paying much attention to detail.

If you lose the required fill-up, for those who do not use 3-gallons regularly:
Example
Driver A - 100 miles - 10% Over EPA
Driver B - 10 miles - 50% Over EPA
Driver C - 500 miles - 60% Over EPA
Driver D - 200 miles - 20% Over EPA
Driver E - 50 miles - 40% Over EPA
Traditional Calc avg. assuming 3-gallon fill =
36% Over EPA
Weighted Calc Explained:
Total of miles = 860
Driver A drove 100/860 = 11.63% of the driving
Driver B drove 10/860 = 1.16% of the driving
Driver C drove 500/860 = 58.14% of the driving
Driver D drove 200/860 = 23.26% of the driving
Driver E drove 50/860 = 5.81% of the driving
(0.1163 x 10) + (0.0116 x 50) + (0.5814 x 60) + (0.2326 x 20) + (0.0581 x 40) =
43.60% above EPA
As you can see, the one who drove more, yet had the best % over EPA brought up the weighted average.
Regarding driving less, maybe another challenge could be who emits the lowest amount of CO2 in a cycle???
