When I first started using ABRP my Tesla was new and the battery degradation was actually negative (-7%) since the 2020 Y has an 82.1 kWh battery and the reference capacity was based on the smaller capacity battery. Since then I have driven 17,000 miles and it is showing the exact same -7% that it did when I first signed up to use live data in ABRP. I know that I don't have a magic battery that is not degrading :)
