I've been a dormant wannabe hypermiler for some years now.
I finally plunked down the $160 and ordered myself a SGII. So far, so good! My one big question is what is the AVG gauge? It appears to be an MPG average of some sort. It doesn't seem to track exactly w/ trip MPG as shown under the TRIP screen. It looks like it's a lot smoother than the instantaneous MPG gauge, though. Does any know how this is calculated?
I couldn't find any mention of this in the manual, in their FAQ, or through my cursory browing here on the forums. Any help would be greatly appreciated.
