In my Tesla group, the advice continues to be given to occasionally take the battery down to 10% and charge back to 100% to keep things well calibrated. I think doing that just because is not the best advice, but fine if doing it as part of a road trip or something like that. If one charges 10%-100% regularly just to keep the battery calibrated, noticeable degradation may eventually become a self-fulfilling prophecy.

that effect depends on the chemistry used in the battery, and is a problem particularly with LFP packs. It is because their Voltage vs SoC curve is very flat. Couple that with the reality that the BMS in every pack "guesses" SoC based on a few things, one being the voltage, it makes it hard for the BMS to accurately determine the SoC if the current voltage can apply for a broad range of SoC. This is why Tesla instructs ppl to regularly full charge a LFP battery to help the BMS recalibrate.
