And what happens with the next cycle. Do we use the current 90 day average and make that the starting % value?

Hmmm. Seems logical. Except that "on the other side" of summer, when temps and weather start to interfere with good FE again, we'll be picking "winners" based on who's losing the least, rather than gaining the most compared to their 90-day average, if you get what I mean.

If we have a minimum fill of 3 gallons and a reset every 28 days won't that even out over a couple of cycles? SG reports are not official, you have to have a fill. It was also intended when we started this that the car of choice was suppose to be a daily driver. I think the min fill requirement will take care of it. 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.

Yea kinda of interesting huh. Sorry to be so slow on this. Ok so the plan is to just go with the original %EPA value when the team was put together? What happens if a team joins late?

No, you're right. For that reason (potential of new teams coming in), it's easiest to re-start each session based on the current 90-day figures.

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???

Nice math, rh77. That looks like a fair way to factor in miles driven. But would we use % over EPA, or use % over our current average at the start of the competition? With the math you've laid out it would be easy to substitute one for the other.

How would you handle those that don't have SG and don't report weekly FE? Or would this be for the 28 day official tally.

But if it is a last 90 day % above total there is pretty much no way a winning team could stay a winning team becasue they would have to beat them selves by maybe 15-20% each month? Or am I reading that wrong. And any new team should have a pretty good advantage as well? So really each team is only competing against themselves from the last month?
