Fuelly data is way off.

[12stormtaco]

I'm putting in the odometer reading, then price per gallon and then the number of gallons and a p if it was partial or not like so. 52014 3.67 11.4p for example. However my mpg estimate is way off and increased my mpg in my last fuel up to 24 mpg avg when it should've decreased it as I calculated I only got 19 mpg. Any help with this??

I do not see that fuel up posted to your log book.
