30% capacity loss is generally considered EOL for battery packs. (And that typically happens at 1000 complete charge-discharge cycles.) The Volt should have gone 1000 * 380 miles = 380K miles before hitting that.
On paper, I wanted a Leaf over a Volt, but the real world difference shows that differing battery technology still matters a lot. I dunno how Nissan built such a bad pack but there you go.

And might have if not subjected to worst-case conditions which EV drivers do not subject their cars to. What are the real-world results in terms of battery capacity declining? They don't seem to be anywhere near that.
So again, as I already said in my first comment, I'm not seeing how this is really relevant - much less some sort of fatal proof.
