SUGGESTION: Fuelly Average OVERALL MPG

[ChewChewTrain]

Fuelly reports that I'm getting a healthy 45.3mpg for my last 10 gas tank refills.

I feel a 10 tank average is way too long a period. Primarily, because once you get the hang of how to get a good MPG score it takes too long to raise your overall MPG score with 9 previous "practice tanks", so to speak.

In other words, Olympic judges don't score an athlete based on their 10 previous competition scores. Their score is earned for that particular performance.

I think a 2 or 3 gas tank, MPG average is more realistic snapshot of one's true MPG, because it ignores all the prior "practice tanks", so to speak.

Thoughts?
