Yep, that's my point, although the it isn't necessarily useless (and I see you said to "just about everybody" so you aren't saying that...).
We'd need to know more about what that information was looking to show...
If it was looking at a "How would batteries perform assuming we remove heat/QC as a variable" then it might still be valid for that exercise.
(Although I can see a lot of reasons that is also problematic, so probably not.. ;-)
My point is just that studies can be flawed, or they can just be taken out of context...
That isn't necessarily the fault of the study, but the person misunderstanding it's focus...
My Leaf, even in Oregon, had more degradation than that. But I was QC'ing multiple times a day.
Yeah, I know.. I had a 120 mile round trip commute. And no L2 at work. So initially I would QC when I got to work.
As it dropped after the first year, in the Winter, I would also have to QC on the way to work and on the way home. Initially, just 5 or 10 minutes (on the way to work, it was nice because I would QC at a place that had a Gas station/mini-mart and I'd get my hot chocolate too). So that was 3 QCs a day. Over the next two years, my mid drive QCs were closer to 20 minutes.
But, as I was using the West Coast Electric Highway ($20/month unlimited) and I could get some work/reading done while QC'ing, it was still fine (and the car was paying for itself that way).
That said, my wife made me agree that when an EV we could afford and I liked came out that could make the commute without having to QC, I'd move to that... And so after 3+ years with the Leaf (which I liked and saved me a lot of money), I moved to the Bolt, which I also really like (although doesn't save me as much money, but lots of time). ;-)
Sorry, that was a bit off topic ramble.. 
Anyway, studies and data are great, but we all need to understand them in context.
It's the DIKW concept.
Data -> Information -> Knowledge -> Wisdom.
The above stats are probably just data (although they could be Information depending??), but by themselves they aren't knowledge or wisdom. ;-)
