This was with the car parked. There is a performance tab that lets you watch many parameters, such as delta V across the strings, in real time, and a logging function.

My old car, now departed, had degraded from about 77.5 to 76.3 kwH nominal after 7+ years and 62k miles.

I believe that keeping the old MS cars cool, covered, and garaged at 55% SoC has a slight, but measurable effect on capacity retention. I don't believe running to 100% does anything more that add a temporary 1-2 miles of RR, even after months of storage at 55%.
