What happened?

Im driving a 2019 Model 3 SR+ with a NMC battery and since the upgrade to 1.28.5 the battery capacity values estimated on the battery health page are a bit optimistic. However the values on the page for the LFP battery seem to be correct.

I was running v1.28.2 previously, where the values on both dashboards were roughly the same.

66kWh estimated battery capacity when new for a 2019 SR+ with an estimated 62 kWh usable now. Previously it showed 49kWh new and ~47kWh now (350km rated range):

The estimation on the LFP page seems to be fine:
