Default Wrong MPG on display???

Hi everyone!
I have a 2015 CX-5 AWD Touring. This is my first time owning a car. I've noticed that the MPG displayed on my dashboard does not match the miles-driven/gallons-spent math. The funny thing is the MPG shown on the display is actually lower than what I get when I calculate it. For the past few months my display has being saying 19.5 MPG, but when I take the miles driven and divide them by the gallons spent (I've done it 3 times now) I get something around 22,5 to 23.5 MPG. Now, I know they don't have to be exactly the same, but the difference here is kind of big. Can anybody share some light here??
Thanks!

Are you resetting the MPG calculation display everytime you fill up?
