Personally, I found the difference between the computer and manual calculations due to the odometer under reporting the mileage by about 2% which I find a positive as it also extends my warranty by the same.

.07%/day *is* almost no evaporative loss
I didn't know about the mileage underreporting in the odometer, but I like it!
So, as the bottom line, it seems that the 2% odometer under-reporting and the ~1% evaporation taken together account for pretty much all of the difference in computer vs. hand-calculated mpgs.
