So basically in other words what this means - is that if battery capacity was over-provisioned by mere 13 percent with battery firmware keeping it essentially hidden - then in effect there would not be any degradation at all.

They already over-provision to prevent users from charging the last few percent. That top end is where the most significant degradation happens when charging.

Like SSDs, the more expensive the drive the more extra storage cells it's got for the controller to use later

That raises the question og whether they study factored this into their analysis. Don’t carmakers already overprovision?

Some do, some do not. AFAIK Tesla does not. My Ford Lightning definitely does.
