The main reason I'm picky is to determine my level of battery degradation. So it started with 78.5kWh (75kWh usable after we remove the buffer) and it's now 69.6.
So a 11.3% degradation in 2 years, that seems high to me.
Probably started closer to 78kWh per the BMS (hard to know exactly for a given vehicle of that vintage). EPA test got ~79.5kWh, but measured differently (Hioki (?) clamps, rather than internal car measurements). This discrepancy tends to always exist to some extent or another but does not matter since we only can see BMS measurements.
Pretty normal capacity loss especially in a warm environment. Since this is for a 2018/2019, it is probably best discussed further in the other sticky thread. Prior to this, the general discussion was covering topics which applied to the 2021 vehicle too, so made sense to discuss here.
