The higher the SOC, the faster the loss. Yes, even down to 10%, the lowest tested.

Unless there is substantial vampire loss due to very low temperatures, a LEAF doesn't lose SOC very fast. SOH is lost faster at high SOC.
So only looking at calendar life, lower SOC is better, all the way down to 10%.
There isn't much reason to leave at 80%, again unless the temperature is low enough for the battery heater to activate. And if it is that cold, you might just want to leave at 100%, as calendar loss is very slow at subfreezing temperatures.
