Actually, measuring the kWh accepted on recharge from "100%" to stop (or at least turtle) using an accurate external meter is a second, more accurate method.
Not really, there are losses...
Of course, but since those losses are known (much more precisely for the "24 kWh" packs, than the "30 kWh" packs, unfortunately) you can use the metered kWh supplied, to find the error in the kWh used report, as I pointed out in the other thread I linked in my previous comment.
Range tests, on the other hand, are very difficult to conduct accurately, since there are many variables that cannot be easily controlled.
No, in 2011-12 LEAFs the kWh used, as displayed on the dash, nav screen and in CW/NC reports is NOT the same value as the LBC's (BMS's) far-less-accurate estimates of kWh remaining in the pack, and I expect that's probably also the case for all LEAFs to date

Yes, but miles/kWh
will be corrupted if either factor is.
And, if you do learn how to do a (fairly) accurate range test, I expect it will be obvious to you that LBC kWh values are so FUBAR that they are best disregarded entirely, if you are trying to get an accurate
estimate of your pack capacity.
After all, if the LEAF's LBC kWh values were correct, this entire thread, and the hundreds of threads and tens of thousands of posts preceding on the same subject, would have been unnecessary...
