Default why do 2008 models have 1 MPG better EPA mileage

Just noticed that 2008 model impreza automatics have one mile per gallon better EPA ratings on the highway than 09-11 models (20/27 vs. 20/26 mpg). what's up with that? is this related to different mechanics/ECU tunes?

It might just be an error in the listing... but if the ECU is to be believed I managed to get 28.8MPG on a recent trip (all highway) without modifying anything on my '09.
