My M3 has different mpg reading

It used to be exactly the same but the past couple of weeks I noticed that the mpg on the cluster display calculates differently from the mpg displayed on the nav. screen. Any idea what's going on? I took a pic of the cluster showing 17.8mpg and the display on the nav showed 18.5mpg.
