Red number in parentheses within profile

Does anyone know what the red number in parentheses is when viewing the "avg MPG" and "last MPG" information in my profile? I tried searching but couldn't find anything on it.

It's your change since last fuel up or change from average, depending on where it shows up. It turns green when things are good (MPG goes up, price goes down, etc) and red when things slip.

It makes perfect sense once someone tells you what you're looking at. Thanks so much, mathowie.
