I see. I don't think I've ever had my Leaf under 7-9% SOC and normally I charge when I drop below 20% so that probably makes it pretty easy for me.
My Leaf is a purely in-town car and while I've done over 100 miles on a single charge (while staying within my self-imposed SOC limits) that is pretty uncommon. Most of my trips are 30 miles or less and for that, it is still just perfect. Hopefully the drop in SOH will slow down now that it's approaching 90%. At least that seems pretty common from what I've read here.
