If you want to trust the miles/kWh figures from the CM/Nav, which of course are calculated by using figures over the CAN bus exclusively from the Battery ECU, of course you can. If you insist, then I have to agree to disagree.
Maybe when you get your LEAFSCAN
you'll come around...
Until then the only hard data anyone can really have is miles per wall kWh, as long as the odometer is trusted. (Unless you want to believe the Gids)
Oh, I'm confident that I will love LEAFSCAN, and of course, we both agree that driver presented data is whacked. From the viewpoint of my range chart, however, we have to work with the tools presented. If I discount everything, there's not much to work with. As a percentage of LEAF drivers, few will have a Gidmeter or a LEAFSCAN.
So, the GoM and CarWings were rightly immediately eliminated from consideration. Even the fuel bars are a bit mushy, but two measurements have held somewhat consistent; the two battery warnings, and for those of us with a Gidmeter, the corrected watt/hour measurement at those landmarks. So, I put a good deal of reliance on those two points, and the Gids. Currently, no other tools exist to do that.
The other piece of the puzzle, of course is miles and economy. We know CarWings isn't accurate, but even if the odometer is not accurate, it should somewhat consistent over the fleet. The same should be somewhat true of the economy meter. Granted, the resolution is crap, and all the games of "processed" data, as opposed to raw data, come in play.
But, without that, we quickly run out of tools to determine the most readily available information to determine range. As is, we can do a remarkable job in comparison to the fleet of engineers who pieced together the GoM.
So, back to the original question. Until such time as more refined, accurate data is available, with the aforementioned tools at our disposal, a Gid appears to fall in the 75 watt/hour range. That merely amplifies the inaccuracies of the economy meter that we use to calculate that number, but again it's consistent (somewhat) until such time that new tools arrive.
For those that never acquire those tools, and must rely on the LEAF presented displays, it's not even a factor, because they won't have a Gidmeter to consider.
By the way, I'll probably make a new range chart dedicated specifically to the LEAFSCAN, since none of the data, like battery capacity, Gid value, etc, will work from the existing chart.
