I had this happen once so far, it spike to like ~90%. I did notice this was after having the car for about 3 ish weeks. I do wonder if it is like, it more adjusting itself to my actual driving. For example, if I am getting higher miles per kwh than what is hard coded in. I think it realizes that my 80% range is not true anymore to the rated mileage (which is currently about 281-285 miles when I leave in the morning). Well if that is true, that is about 88-89% of the "rated" 319 miles. Which while that math doesn't 100% line up, I think at least points towards not an over charging (for me) but more it recognizing it can/does get more range than projected (which for me makes sense, I rarely drive on the highway and most of my driving is stop/go city driving going about 35 mph). Wonder if that explains some of random range spikes for some.

If I am reading your message correctly you think the SoC (%) is adjusting for the GoM (Guess-o-Meter). If anything, it should be the other way around.

The SoC should be based primarily on the voltage of the pack, with the voltage corresponding to some calibrated level of battery charge. The GoM is based on the SoC plus some formula which adjust for prior conditions and driving experience.

After all the 319 miles is not fixed-in-stone, but based on average driving conditions at a 100% SoC. It can be higher this time of year and maybe into summer, but lower in winter.

That's fair, I just have noticed that my guess o meter now settles at a much higher mileage after that event compared the SoC. But point well taken
