That’s not really bracketing 50% then, that’s bracketing 60%
By straight math averaging you are correct but it stays closer to 45% to 50% for a much longer period of time than at 75% based on my driving habits.

85% once, 80% five times, below 30% three times, else always driven 30 - 75%, store at 57% a year ago now store 50%.
I don't think I ever was above the degradation threshold. Some packs are better than others. Maybe I'll get a new pack in next 6 years.
The downside is that you're not getting battery management recalibrations at different states of charge. Nobody drives exactly the same amount every day, so the SOC when it sleeps before charging is somewhat different, and that helps the BMS.
Your proposed way would only see sleeping at 50%.
Personally I would keep as you're doing now, charging late at night/early morning. Even if your electricity price is the same, the reality of the utilities is that they're using dirtier and more expensive generation in peak hours, which are late afternoon through mid evening.
I am uncertain that is critical for day to day driving especially when battery % instead of km. It is more critical for Maybe for a long drive where distance between charging stations requires more accurate battery estimations.
Additionally, does the "late night charging" mean the car is charged immediately upon arrival home or does it mean charging late at night to take advantage of lower electricity prices which suggests that the car had a sleep between arriving home and commencement of charging.
True, but there is little to be gained from starting charge immediately, unless you're starting a long trip late at night, a very rare occurrence for most. If anything the environmental issue can make the otherwise even choice go to one side.
The second. I use off-peak time scheduling. My off-peak ends at 6AM so it finishes charging by 5:45 automatically. It will sleep for hours then from the time I get home and plug in until start of charging.
Of course I'm in San Diego which has extortionate electricity rates outside the EV plan and super-off-peak. But even if the rates were the same all hours, I would still do the same thing.
That's what I mean . I suspect that when Kenblub says "late night charging" he could be referring to charging at some point in time after car arrives home - not charging immediately.
I really meant off peak charging. I just couldn’t remember what it was called
. Thanks for the advice. I now still plug in when I get home but jiggle my off peak charging time to coincide with when I plan to leave. For example, tomorrow it’s set to 11:00 am.Just a little comment to reduce a risk of mixing up terms:
I usually describe ”charge late” which means to charge so the charging session is finished not very long before the next drive.
This has nothing to do with off peak charging in this case, and has the one and only* reason to shorten the time at high SOC this reducing calendar aging.
*)There’s actually one more reason in winter in cold climates = to have the battery at the maximum temperature before the drive which gives lower consumption and longer range for heat pump equipped Teslas.
I wish people would stop obsessing about the battery. My LR rwd 2019 model 3 I’ve had since 27 miles on the odometer probably has degradation but frankly it works, gets my to road trips and all that and I charge primarily at home with supercharging few times a month. Reminds of macrumors posters posting about their iPhone battery health going to 92% after 1 year. Just use the damn thing and get on with it. Jeeeeeez. Big woop it went down 10 miles. Could be bms getting all wacky but why does it matter when it works and your not stranded.

Because some people like to do that. Like me, I don't care about loosing a km here or there but I do like to keep my battery in good shape. I find the subject interesting so motivated to learn more. I don't bother you about your likes and dislikes so leave me to bathe in my battery gloriousness
How often do you wash the car?
How often do you rotate the tyres?
To each their own and if people want to obsess over it so be it. My only concern is people might overhear people nerding out about getting the most out of or taking the super best care of their battery and think that's expected overhead of owning an EV and it's not.
I'd rather nerd out about the battery (where there is some interesting science) than ceramic coating mumbo jumbo (where pseudoscience abounds)
And the very nice thing is that it does not take a lot of effort to cut the degradation in half.
And the ones that doesnt care at all could better skip reading posts on the subject than complaining about it
