You know, I did misinterpret the study data pretty hard. Hazards of rushing a comment I suppose.

Though, the same article I shared does highlight that the major EV manufacturers do warranty for 30-40% degregation within a 8-10 year period depending on the manufacturer, which even taking the best combination of those 2 values (30%/10 years) does mean that the manufacturers have decided that they could, in their worst case scenario lose up to 3% capacity per year before they'll honour a warranty. So... take that how you will I suppose.

As for the cherry picking, I'll admit that was disingenuous, but not intentional. Again, rushing research causes sloppy mistakes.
