I have not measured Max power at 100% SOC since the last full charge. However the kW display indicates less power. At 100% SOC the pack voltage is 391v, cell average 4.07v, 61.9 kWh usable full capacity. So Max power is definitely less.
I'm not sure to what you referring. FWIW, I did check the reported distance today — at 85% it's showing a range of 189 miles, which would calculate to ~222 miles full charge; I also rechecked the full-charge capacity while supercharging today (which again was capped at 60 kW, though it could be a faulty supercharger — one of the plugs was out of order), and it's now down to ~66.75 kWh… but my rate of charge doesn't drop off nearly as quickly as it used to — I was still pulling in 58 kW at 80%.
Looks like we've got a graduated soft cap being applied here; who wants to limbo? How low… will it go?

Sorry but that is just not possible.
That basically means your old values would state that you had NO degradation. On a 2012 car
71kwh is perfectly fine.
I had a little — it was around 77-78 kWh when I first got the car not-quite-2 years ago with a little under 43k miles on it, and was around 75-76 kWh (75.8 if memory serves) when last I checked sometime in April after having put on another 22k miles; that it dropped to 71.2 within the span of a month and a half, then to 66.75 another 2 weeks later (who knows how much further it has yet to go) is neither perfect nor fine, but at least there's some semblance of a rationale behind it.Sorry but that is just not possible.

Good point — it is an original battery pack (limited to 90 kW supercharging and all), but the original battery pack? They told me it hadn't been replaced, but who knows… I certainly don't know how to check the battery pack's odometer — I presume there's special equipment and/or a service (which requires my Tesla credentials) that could read that?

Interestingly, after not being able to charge beyond 97% three times, last night I reached 100%. I did not experience the same 2kW or so slow charging beyond 95%.
Note the pack and cell voltages below. The data is from a few minutes after completing the charge. The pack also seems to have gained a kWh or so from a few days ago.

My car stalled at 1kW and 96% last monday, like yours. After updating to 2019.20.1 (from the ominous 2019.16.2) my car exactly replicated your most recent behaviour. Supercharging to 99% now yields 328 km.

I just installed 2019.20.2.1 and SC this morning to 90%
I got no added range back (didn't expect it)
I did see limited initial charge current. I used to get 105kW or so, today it went to about 85kW before settling at 74kW

Does the lifetime chischarge kWh roughly match the mileage of the vehicle for your lifetime wh / mile usage?

It was immediate for me also. Which is why it was a concern when I noticed 3 miles degradation, then 10 miles on the following charge.

Sounds similar to my experience. Prior to 2019.16.x firmware, I was getting throttled Supercharging. Then it appears 16.x opened that back up when I think they bumped up the Supercharging rates to 150kW. Now it appears it has stepped down again after 20.x. My SoC wasn't as low as I liked and I was having problems with it displaying properly on my screens so that could have affected what I was seeing. Will know next time I SC with lower SoC.
