I haven't downloaded the telemetry but we drive it every day and the range we get is extremely consistent. I'm sure there must be some degredation but my point is we haven't really lost any range. The weather and our driving behavior is the main cause of range variation.

If his claims about losing 50% capacity after 500 cycles were remotely true that would be the main cause of lost range ina 2.5 year old LEAF.
