I have primarily supercharged my 2018 Model S (100kw) over ~140k miles and only have 8% battery degradation.

That assumes the battery degradation number calculation is 1) accurate and 2) isn't lying as to not discourage people without access to regular slow charging from buying their cars.

Provided by a third party, not Tesla.

[Nextgrid]

You mean a third-party is giving you that number? How do they obtain/calculate it? Do they just read a data parameter via the car's diagnostics port? If so the lying argument applies just as well.

And you might have less degradation if you had L2 charged it primarily.

The evidence does not support this when scoped to Tesla battery packs.
