Partial fill-up clarification
I'm a little unclear as to what is done with the partial fillup data. Is it completely ignored? Or are the total miles and total gallons between fillups calculated to determine mpg?
For example: say you fill up, drive 400 miles, put in 1.4 gal. because it's close to empty and you only have $5 on you. Drive another 20 miles, get some cash and then fill it with 9.1 gal.
Wouldn't the calculation for the fillup be:
(400 + 20)/(1.4 + 9.1) = 420/10.5 = 40 mpg?
Or would it not calculate mpg for the second fillup and wait till the next fillup? That would seem strange to me.
