This has been discussed a few times in these forums, including my post here https://mirageforum.com/forum/showth...rip-MPG-report
Since that thread, I've been keeping records by resetting my MPG-B meter every time I filled up, so here is some real world data. A minus (-) means an optimistic measurement. Plus (+) means pessimistic.
MPG-B difference from calculated (in MPG)
-2.1
-1.1
-.15
-4.2
+1.9
-.20
-1.0
Summing, and dividing by 7 equals -0.98
So I will assume my meter is approximately one MPG optimistic.
