The few times Tesla has addressed battery degradation, they have simply lied and dismissed it.

FWIW: without using any more or less fancy app, my 2020 LR AWD started at 504 km displayed range. Now, 144,000 km (89,500 miles) later, 100% charge equals 474 km. Maybe there is more to it, but to me, that's 6% less mileage than what I had when the car was new. I can live with that. I regularly charge the car to more than the recommended level but I start driving right after I reach my target, and then arrive at home at the recommended 80% (or 90% when that was the recommended maximum).
To me, range continues to be a non-issue.

You mean you cycle from say 95% to 80%? That's not the optimal practice.

Depends on what you are optimizing for. If battery life is all that matters, yes, then it's probably best to keep the car at 50% SoC in an air-conditioned garage.
To answer your question, it takes about 5% SoC to return home from my daily commute, so I used to charge to 95% and arrived at home at 90% when Tesla thought it was okay to go to 90% for daily use. Now that the changed their mind and think that the battery shouldn't be sitting at more than 80%, I charge to 85% and when I come home, it's at 80%.

My personal car is an automobile, and I like it that way. It happens fairly often that I decide later in the day that I want to go fly (roundtrip to the airport ~200 km) or that I have something to do in Ottawa, which is roughly 80 km away. I want to be able to jump into the car and just go. To me, it's not paramount to optimize the last little bit of longevity out of the battery when it can clearly handle being charged and stored at 80%.

Also, correct me if I'm wrong, but hasn't Tesla debunked that "supercharging is bad for you car" myth a while ago? That may have been an issue with older models, but as far as I remember that's no longer a thing.

I'm finding the approach a bit puzzling. Why charge to 85 instead of 80? The way you are doing it, the car is spending some portion of time above 80% ... and possibly not an insignificant amount of time either, depending on when you put that charge in relative to your next drive.

Like I wrote in #13: I start driving right after I reach my target, and then arrive at home at the recommended 80%. If less than half an hour is a significant amount of time, then so be it. I've logged almost 90k miles with my car so far and don't have any crazy degradation.
To me it's more important that I can drive my car if and when I need it without spending hours to charge it first. This convenience is worth dealing with a slightly increased wear that, at least in my view, probably won't make any difference.

if you drive within half an hour of charging, seems mostly fine. It just appeared that you were going off Tesla's recommendations, and the recommendation is pretty specifically not to charge past 80% except for trips ... the advice isn't "charge past 80% daily and bleed it off immediately". FYI, the battery undergoes more physical stress when charged to its highest levels, so charging and then driving immediately only avoids the calendar aging portion of degradation, but not cycling stress.

None of that is to say your approach is wrong ... if you sleep better with 80% range, then go for it.
