And yet I have 12% degradation on my 2020 SR+ after only 42k miles. Tesla can cherry pick all they want but on average most of their battery packs are around ~13% at 100k if things like teslascope etc are to believed.
I think a lot of it has to do with luck of the draw, but most tend to loss 10% in the first year then hang out there losing a 1% or so each following year.
