Do you drive it like a maniac? That has a huge effect on mileage. It calculates to around 19-20 mpg assuming you are putting a little over 10 gallons in which is a little less than what I am getting.
On a side note, I calculated my MPG just driving around in boost and it calculates to around 6.6 MPG, so you can really see how a lead foot can affect your mileage.
