I'm in the same boat as Bernard, south of Seattle with a 74 kilomile 2016 that hit 63.4% SOH on 1/27/22 when I set my dealer appointment for warranty EValuation.
A job change meant that I went from over 151 miles per day of driving (with 4 DCFC) to largely virtual work, and usage dropped to maybe 12 miles per day average in warming weather. By the time the dealer measured SOH, it was a freezing cold day but the BMS reported a lousy 70.3%!! Faced with my SOULSPY data, KIA of Puyallup opened a TechLine case and tested again the next day, but Corporate told me to come back later with a reading below 70%.
Appointments are still running 6 weeks out, so it'll be mid-April before I take another crack at the SOH meaurement.
At least I got a car wash out of the deal....
Hey Bernard, come on up to the Seattle EV Association meeting this coming Tuesday and we can compare notes. https://www.seattleeva.org/wp/
