I got it Jason, thanks. And a big thank you for working on it.

I'm not sure how the data presented will be used, but I have to mull it over some more.

If I may go back for a moment. I am looking for a way to answer these questions with more accuracy:

1. If I had car A rather than car B, what mpg differences might I see ?
2. I am thinking of purchasing car A. What mpg might I expect to see for my locale and average trip times, if I am a lead foot/average/hypermiler type driver ?
3. I own car A. How am I doing mileage wise, compared to my nearest peers ?

It seems that one would want to cut across every driver's experience, rather than one driver at a time, to answer these questions.

Cheers -- Eric
