Beats me. My 11 bar '13 is at 4279 L1/L2s and 0 QC since it has no CHAdeMO inlet.
The count has quirks anyway: https://www.mynissanleaf.com/viewtopic.php?p=589843#p589843. For all we know, it might've been intended to measure something else like contactor cycles rather than being an actual L1/L2 count.
It is hardly driven now as I'm driving my Bolt which isn't driven much either as I'm WFH due to COVID. Pre-COVID, I'd go to work and L2 charge either car for free there. Now, Bolt is mostly getting free or discounted juice via https://drivethearc.com/ (limited parts of Nor Cal only) which doesn't help my CHAdeMO-less Leaf.
I'd imagine that older cars than my Leaf which are still being actively driven + using timers have way more than me.
