This is an interesting comparison:

Wall energy using L1 charging from 0.2 miles below VLBW to 100% prior to drive: 27.17 kWh

Car charged the night before to 100%, and left plugged in for another four hours after charging was complete.
I'm fairly certain I left our LEAF plugged in for the extra four hours, also.

Total number of legs driven: 10
Ambient temperature range for the driving: ~65F to 85F
Battery temperature range for the driving: Mostly at 6 temperature bars but a small amount at 5 bars
NullPointer said:
Temperature 81F, crosswind (from west) at 8mph, climate control off, fan on low, regular 200W draw from other systems. The route has speeds of 30 - 55 mph, typically 45 mph, occasional lights, moderately hilly with the elevation regularly varying between 500 and 900 feet. Route was straight out and back, destination same as starting point. Six temp bars throughout
Conditions were quite similar except my drive was broken up over a couple of days/drives.

Miles to LBW: 88.7 mi. (FWIW, 10 was showing on GOM.)
Miles to VLBW: 100.3 mi.
Miles total: 101.0 mi.
Dash efficiency: 5.7 mi./kWh

LBW 100.1 10 8.6 5.7
VLBW 108.7 -- 9.4 5.8
Same dash efficiency for the drive, but NullPointer's LEAF goes 12.4 miles (13%) farther to LBW and 8.4 miles (8.3%) farther to VLBW.

Recharged to full overnight at 120V. Measured 27.1 kWh using a Kill-a-Watt meter. Total charge time 19 hours. Charged in garage, outside temperature range 91F - 67F.
Nearly identical energy used to recharge after the drive, even though NullPointer went all the way to dead.
So what can be concluded from this data?
The most obvious (and very possibly the correct conclusion) is that NullPointer's LEAF has more battery capacity than our LEAF and therefore more range but the recharge energy reads about the same due to inaccuracies in one or both of our energy meters. We could probably find out the answer to that question by comparing our meters.
But what can be made of the fact that our LEAF went 12.4 miles versus 8.6 miles (44% farther) between LBW and VLBW? Unfortunately I did not record efficiency carefully like NullPointer, so I don't know if I achieved over 8.2 miles/kWh during that portion of the drive. I may have, but I do not remember what I did that evening.
Could edatoakrun and GerryAZ's theories about LEAF instrumentation degradation and more capacity lurking below LBW be in play here? Maybe, but I suppose that may just be wishful thinking on my part.
So, NullPointer, do you want to compare meters sometime?
