I understand that the bars and miles do not have an exactly linear relationship, but any guess as to how far off the two are? Joe, it sounds as though you don't believe there is that big of a difference. Would that mean, in general, we could probably take the miles driven divided by the bars used to get an average miles per bar and "roughly" apply that to all the bars?
On my way in to work this morning, I measured exactly the miles driven over the entire course, 15.3 miles. Once I parked at work, I saw that two bars had been used. Granted, I have no idea if the second bar had just dropped off or if it was very near to dropping the third bar or halfway between. In any case, doing the math and assuming a linear relationship (which it isn't), I would get roughly 7.5 miles per bar if I continue driving in the same style as I did this morning. Being kind of iffy on the state of the 2nd/3rd bar, my total range on this charge would be anywhere between 80 miles and 120 miles. Obviously, it most likely is NOT going to be close to 120 miles, but if I can safely assume 80 miles on the low end, I would be happy with that.
