Smartcraft. How is this right?

[Bridog]

On a recent trip going very slow most of the time my Smartcfraft trip history log showed this. How is it that we went MORE miles then gallons of gas used, but yet the MPG is lower?? Am I reading this incorrectly?

the .9 MPG is you're fuel brun rate. so you can do the claculations one of a couple of ways.

miles traveled * burn rate = gallons used
Gallons used / burn rate = miles traveled


So base on these calculations and allowing for some variation in speed or current. I would say the smartcarft looks right.

Doesn't look like smart craft is so smart after all. It seems close enough though. I would also think the calculations would be more accurate.
