I think LeafSpy is going by voltage? In the above case, 97.6% SOC (329 GIDs) is 100% on the dash, while 27.3% SOC (74 GIDs) was 20% on the dash.
We should probably ask Turbo3 about that since he wrote Leaf Spy. I'd like to know what SOC actually measures and why it shows 97.6% at full charge?
Update: I e-mailed Turbo3. The answer is: SOC represents the actual state of charge of the battery as reported by the BMS. The Dashboard % is an adjusted value that takes into account Nissan's safety margins for charge and discharge limits. SOC is absolute capacity while Dash % is useable capacity. Turns out that this is buried in the help file for Leaf Spy. My bad.
Okay, I didn't reach LBW, but came pretty close at 53GIDs. LeafSpy reported SOC of 21.2%, while dash showed 15%.
So with my "healthier" battery, it seems I have more access to the lower voltages?

Not really, I'm pretty new at this!
Lots of possibilities and theories of course:
bad batch of batteries,
chemistry need to be tweaked,
jamming 30kw worth of batteries into the same space as 24kw was a bad idea.
Best case, by the time my degradation warrantee kicks in, Nissan will have figured something out.
Worst case is i'll get multiple replacements over the 8 years; and once the car is about 9 years old it will not be very practical, though short range doesn't bother me too much as I'm used to bicycle.
Really like the car, though. our first EV.

You know this as fact based on your overall rigorous analysis of all potential factors and can arrive at a conclusion, right? Please!

Bolt battery degradation is unknown, and the GM warranty replacement at under 60% capacity is nothing to swoon over.
