My conclusion, subject to change with more data, is that the 40kwh pack degrades much like the Wolf Pack (4/'13 - 2014): it doesn't degrade fast if kept cool but does if kept hot. It may be more sensitive to moderately high temps than the Wolf pack, which if true means that multiple QC sessions should be avoided in warm weather...
My conclusion about the 'Wolf' pack is that the range of experiences is wide. It would not surprise me if the 40 kWh pack fairs similarly ... which would actually be good news since it is a bigger pack and carries a longer warranty than the 24 kWh LEAFs. I would not care to play the LEAF lottery with a new car purchase but it does suggest that informed purchase of a well behaving 40 kWh LEAF coming off lease would be reasonable for gentle use in non-hot climates.
This is my pampered 'Wolf' pack over the past 27 months, which I think fits in the well behaved group -- for LEAF, anyway.
The initial loss seen in the graph is actually the tail of a 10% loss in capacity after I bought the car, I presume part of a reset calibration.
