Yes, but you do many QCs, which increase the estimated SOH.
Several experiments have shown usage and not method of charging has the greatest effect. Realize NCTC for me lasted only 90 days on my 2013 so it was charged at home on level 2 about 90% of the time. It did the same; had like new stats for first 8 months and 10,500 miles
This is complex, and I agree that usage plays a large factor as well. Also does battery temperature, not just for actual capacity (lower at low temperatures, maximum at some temperature around 25 C, lower at higher temperatures), and capacity loss (a longer time needed) but also temperature and temperature change impacts capacity estimates. Several experiments doesn't cover the complexity.
I look at the 97.35% (or whatever) readout from LeafSpy and remember that true State Of Health could be anywhere between 94% and 100%.
I've found ways to force the capacity estimate up and down. I don't have any reason to think this changes actual capacity.
