My reason for asking is because when you sit at idle you can just watch the econ drop a/b .1 MPG like every 5 seconds??? IDK can somebody explain this to me? It said i got a avg. of 19.1 last tank and i did the math * how many miles i drove/gallons of fuel put in vechicle @ fill up. & it said 15.5?
So what has been y'alls experience?

I've felt it was always too high. But, according to Bill it uses a sample of 100,000 readings (about 27 driving hours or maybe 6+ tankfuls) as a database.
It's not going to match your calculations at a fillup. But, if you sit, going nowhere, the miles driven is zero and the average is going to drop - even faster if you've "zeroed" it out recently. So, when did you last "zero" it out? Last year?
