So,
How do we think that compares in reality to Tesla’s?

For one thing, these numbers aren't meaningful. A 7.5% cycle count difference over a few months isn't enough to actually see any degradation.

89% already on a 2019?

I'm coming up on another adjustment in about 2-3 weeks, but I'm hoping to see "not much" adjustment as the battery has been averaging around 48F the last few months.

Yes. Probably due to hot summers in TX, parked outside during the day, and almost daily QCs. My next vehicle will be a Leaf Plus or a Niro EV because I need adaptive cruise control and more range.

Don't feel too bad, I expect to drop into the 80's quickly this summer. We have cool winters but blazing summers, and I also park outside. I was at 91.74% as of yesterday and haven't even owned it for a year yet (May), AND I only have about 4300 miles.

I'm appalled at the idea, but I could drop into the SOH 80s as well this Summer. I was at about 92% last Fall. I only have about 3300 miles on mine.

So you're expecting >11% capacity loss in under two years?

This is a new generation of battery, so I don't know what to expect as the years pass. I do know that protecting my battery from extreme heat and driving it few miles, while keeping the SOC fairly low, has done little or nothing to slow degradation. I like driving the car, but I'll likely turn it in to lease an SV Plus with Around View, and then maybe buy that car if I'm still driving when that lease ends. I had hoped to buy this one.

Has anyone figured out a relationship between HX, which people seem to think is a measurement of the internal resistance of the battery, and SOH?

Tracking my data HX has been a bit odd. While SOH has slowed to a crawl during the winter, HX started going down in the early winter, I did one fast charge and it shot back up and then reduced a bit after that then started climbing again. Why would HX drop at the start of the cooler temps but now in late winter start rising with the same cooler temps? Seems a bit strange to me. Interesting to plot though. I'd also be curious to compare HX from one person to the next. We seem to focus a lot on SOH. (Assuming HX actually means anything)
