Well, in the thousands of posts I've made, I've detailed it a few times. It's not complex. I got it in December of 2018, and set my nightly charge to 80%, within 6 months, I had changed to 60%, based upon reading that the cathode cracked at 3.92V. I estimated that was 63%, so I decided to charge up to 60%. Much later, I found out that 55% seemed to be the sweet spot, but I had been doing 60%, and it had been working, so I decided not to change things up. My car lives outside in a carport, and I don't baby it.
Now, roadtripping, I charge up to whatever level required, 80%, 90%, etc. I just don't leave it at high levels for too long. That's from the Recurrent app, and it too shows my car is an outlier:

As you can see, I set my nightly charge to 60%, but sometimes I charge at higher SOCs, and sometimes I charge at really low SOCs. The 80% line at the beginning of March was just spurious data. I charged to 80%, then went to the airport and parked. I left the car at 60%, but Recurrent thinks I was charging for 2wks at 80%, when it was sitting in an airport parking lot dropping to about 53%.
I always plug in at night. My daily trips are about 20-30miles, so 60% down to 50% and back to 60%, usually. I tend to drive a higher proportion of road surface vs highway, but I usually drive about 10-15mph above the speed limit.
In the SMT data you can see how much of my charging was AC vs DC, so I did plenty of Supercharging. My car is set for max regen, and I don't raise my SOC to balance cells or anything, they've always been in the 4 to 10mV range, but usually 4 to 6mV.
Seriously, I don't micromanage the car, I set the SOC to 60% and that's been about it.
