Just FYI on the charging speed on the 90KWh pack. After 2020.48.37.1 or later, Tesla restored back the charging speed. I use to be capped at 87KW charging rate for many years after the 1st year of owning the 90D with heavy supercharging usage. Now I can get up to 116KW at peak and it stays there for most of the early charging up to around 60% before going below the 100KW mark. As for degradation, that is still in the air because Tesla did cap me at 87KW - 90KW for years so maybe the battery wasn't hit as hard. Again I am a very heavy supercharging user.
