Another observation I had that may help is that (on a short run at least) current is capable of some level of accuracy.
I drove to the supermarket earlier and Current (large digits) said less than 0 mpg (0.4 or something), however, on the way back I arrived home with it showing 28mpg which is pretty realistic.
