Well, there you have it. Looks like degradation is the same.

I believe we need more data. These graphs just show average. But can we get also median value? Can we also get the worst and the best distribution, etc?

There isn’t any fancy measurement taking place, just a report of the miles displayed on the dashboard as a % of the original when the car was new. I heard (maybe not now?) that Tesla kept back some of their cells from use when new so that they could come online over time to disguise battery degradation. If that is the case then this study wouldn’t show that as a different number of reserved cells could have come online for cars charged differently if the degradation was different.

I linked a report (Canadian based research outfit I think) in the BaseLine Soh thread that basically states the opposite (but need to re-read)! When I get a chance I will add a link to that specific post.

UPDATE - that report from www.geotab.com and two of the relevant charts I posted in Post #1 of the Baseline Soh thread below - see 2nd/3rd last charts near end of post #1:
