Does anyone yet have any insight as to why some batteries flatten at 91% others 93% (my cars included), and one report of a battery staying at 97% (battery lottery winner?)
Yeah, I do. Don't put too much into the early results. Remember a few weeks ago, I was one of the ones in the 91's... so "flattening" anywhere in the first 2 years is probably not a the best term to use.

Actually, given the short time of the data sampling interval, about 3-4 months and the randomness of data between vehicles,
one might reference an area of statistics defined by a Stochastic Process. In summary, the data sampling yields
no conclusions attributable to the population of vehicles, i.e. the 62kWh Leaf+ battery.

And in a very uncharacteristically moderate tone, I might add.
