I charged almost exclusively at DCQC stations for the first 2 years. 95% of my trips are for local around town errands, which typically use between 5-20% of a charge, so I could easily go 1-2 weeks between charges, only stopping by when the SOC got down to about 20-30%, and arriving home/storing at 80%. With DCQC stations at multiple shopping centers near my home, I found it convenient to charge while grabbing some quick groceries. No waiting, no real hassle. I also live in a relatively cool temperature area (battery averages in 56F-63F before QC) so no big temperature concerns.
If I had a daily car commute, where I had to QC daily, that'd get old pretty fast. Different circumstances. I don't need to shop daily.
Once NCTC ended, I installed an L2 OpenEVSE charger at home and use that pretty exclusively now. It is nice almost never having to account for charging when driving, since I always have enough charge when leaving home. That said, I still don't "leave with a full tank", I keep my SOC between 30-80% to maximize longevity/calendar life, only charging higher when I anticipate needing it. As before with QC, Given recent battery studies I might aim more for 30-60%, given that that's still multiple typical trips for me, probably 3-6 days on average. Given how fast 6.6 kW charging is, it's easy for me to add some back quickly if I think I might need it.

I like in UK and it isn't too hot outside very often. when I get my car serviced the battery report says "avoid frequent use of CHAdemo". Does anyone have an idea of what is frequent -is once a week, once a month etc. All help much appreciated
In two years I did 116 QCs or 1.1/week on average. A few dozen of those were part of multiple QC-in-a-day range extended trips. On my Nissan battery checkups under the category "Charging: Frequent use of Quick charging" they scored 4/5 with the Recommendation: "Your score is very high and good for your battery." So I'd guess if you average between 1-2 times/week they'll consider it fine. Frankly, based on the LeafSpy data I've seen from other users who QC frequently, it doesn't seem to have much impact *if* your battery stays cool. An occasional twice-in-a-day in a cool climate seems like not much to worry about.
