However, from graphs of the current, the LEAF takes a substantial "siesta" before the last "burst" of charging.
Thus, the constant-current assumption that you were using is substantially wrong, especially for short-duration charges like your 1.8 hour charge. Perhaps 0.4 hours were "siesta" (zero current), and another 0.4 hours with the current tapering off (perhaps averaging 75% of full current).
During the "siesta", the cells MIGHT be doing some voltage-equalizing.
That's an encouraging concept - but do you believe it holds true to that extent even for an 80% charge? If it is the case, and the described L2 charge took less than the estimate based on constant current, that would indicate L1 charging is vastly less efficient, because the 14.85 kWh L1 charge to 80% (and accompanying low m/kWh) was measured, not estimated. That L1 charge measured total was also pretty well in line with the max constant L1 current multiplied by the elapsed time (14.85 kWh/11.5 hours = 1290 watts), which points to minimal "siesta" time if any when going to 80%, at least at L1.
