I am just suggesting the refresh is related to energy density improvement. The kWh numbers in EPA tests are just too "random" to explain.
For example, Why didn't Tesla pick another 2021 LR car with ~80.8kWh after they performed a test with only 78.557kWh? Impossible for us to explain.
"OEMs do the range testing in-house to the EPA's specifications and provide the report to the EPA. In about 15% to 20% of the time, the EPA takes the report and conducts its own testing in-house to verify the OEM's data."
