Can you add a checkbox on the "Add a fuel-up" screen that indicates that there's been (at least) one fuel-up that hasn't been entered since the last one, so this fueling shouldn't be used for MPG calculations?
I've just imported a bunch of olde data for
my Civic, which I had kept on MyMileMarker until April this year.
Since then, my car has been driven from Boston to San Francisco.
I fear that when I enter my next fuelling, it's going to see that I've driven about 4,000 miles on "a tank" of gas, and decide that my little Civic somehow does 400 MPG.
