One of the things with the old challenge is that, if a team did very well early on, they would reach a brick wall of e.g. 240% above EPA. Then they will become the losers from then on,, whereas a team with gradual improvements up to 180% EPA might 'win' more often overall.
I think there should be some kind of formula, where you set your current mileage (e.g. 20% above EPA) for each car as the 'zero' mark. Then, if you are 15% above that, you score 15 points for the team. But also, there should be a 'delta' score, for the percentage change.
So, if someone starts at 20% above EPA, and gets to 80% above EPA, they will get 60 points + 60 delta points. If they remain at 80% above EPA next cycle, then they get 60 points + 0 delta points. This would give a way to reward people who keep high MPGs but can't improve as their MPGs are already so good.
Starting the competition with the car's starting % above EPA as being the 'zero' mark would allow newcomers and longer-term hypermilers to compete on a more level playing field.
If I join the competition I will be making some BIG jumps with my manual gearbox, when it gets fitted, and extreme aero mods
