Thanks, it's encouraging to hear that I'm not alone here.

This is a great discussion, and perhaps I can make a quick comment.GaslessInSeattle said:In any case, if there is a consistent way to do better than Tony's chart we better nail it down, as the Jalopniks out there are going to use overly conservative numbers as cannon fodder for their war on EV's.
I've been experimenting with several ideas that would allow more dynamic battery capacity estimates. This would be based strictly on instrument readouts. It looks like it's possible, but it won't be as accurate as if we utilized CAN bus data directly. I believe that the best accuracy we can hope for, all things considered, is about 2 or 3%. This could easily translate to 2 or 3 miles range difference, and it might not be always acceptable.
TEG brought up an interesting idea on the Tesla board. What if we came up with a connected device, be it a smartphone or a tablet computer, that could access the CAN bus and deliver a more accurate real-time battery capacity and range prediction? Some say that this cannot be done, and if it was possible, Nissan would have already implemented it.
With all due respect, I disagree with this view. I think that with the known CAN bus codes, and our current understanding of the battery, we should be able to come up with better DTE gauge.
