yeah, looks like your April fills are off. I took a look at all fuel ups and on April 20 your odometer said 88221, and then on April 21 it said 87811, so there are probably some fuel-up dates transposed along the line. If you fix those up and re-import you should be set.
Why wouldnt the system sort fill on teh same day by the miles ?
It should, so I'm not sure why you had the glitch with that day. It could have been a problem with the import process and having fuel-ups recorded at exactly the same time on the same day. I recalculated your mileage manually on this end and it looks like things are lining up better on those problem days now.
heh, nothing is angry. When you mark a fill as partial, Fuelly skips calculating the MPG for that tank and the next one. Fuelly needs a baseline full tank to start calculating MPG for individual fuel-ups again. But all of fuel-up data goes into calculating the average MPG of the vehicle, so it's still worthwhile to include partials.
