I have the same EVIC system and there's no magic algorithm on my truck that gives it 0.1 accuracy.

Not slamming the 6.4 gasser on mpgs, just the EVIC and it's accuracy :B
It shows 99mpg because it cuts fuel to ZERO. And most EVIC readout, GM HD trucks excluded, are more accurate than most people are at math.
