MPG change after ASS off service

I noticed this and I'm hoping some one can clarify this for me, since the dealer can't.
I took in my car to get my ASS to remember last. I had about 1,500 miles on it. It took me driving on Highway during break in on eco pro to get over all MPG to be 26. So when I picked up the car for some reason it was at 22... Not sure why it dropped all of a sudden. And for it to drop like that it'll take ton of miles driving crazy.
So now I'm having to 'build up' to my 26mpg (entire ave) by driving more on highway for another 1,000 miles.

Does this make sense to anyone?
I know my trip mpg can go up to like 33 when on Highway allot. But still can't figure out this over all mpg changing like this.
Dealer said it's because my ASS is off and told me to do master reset and see if help change it back.

Have you actually calculated the mpg?

No just going by what's on my dashboard.

Please ignore this post.... Learn something new everyday about this car.
Founded out I can reset that mpg in the dashboard. I realize this number really doesn't matter all that much.
Just need to stop looking at these stupid things and just enjoy car!

Haha, I only did that during the break in period. Want to go past 1200 miles so bad I just got in the highway and drove. It wasn't for the mpg
Still enjoyed the ride. Now it's much more fun to drive!!
