Read this thread if your LEAF needs the NTB-11-041 CarWings update :

If your LEAF doesn't need the update, probably the only thing wrong with your LEAFs CarWings kWh use reports, is that you are not using them.
In the OP:

...We drove about 69.2 miles until Low Battery Warning (LBW) at 3.9 miles/kWh, and an additional 8 miles (12.9 km) to Very Low Battery (VLB)...
Unfortunately, I cant find any report of the dash m/kWh at the VLBW or at the end of the 2/24 test.
Pchilds, do you know what your dash m/kWh was when you got the LBW?

...100kph GPS, 36 psi tire pressure, 5 temp bars at start, 6 at finish.
Start GID 249
LBW 65.7 miles
VLBW 77.2 miles
End GID 18
m/kWh 4.8Total miles 79.9
Weather, traffic and temperature were the same as the last test.
Even absent the report of what both LEAFs dashes, nav screens, and the more accurate CW kwh use reports showed at the same LBW or VLBW, is pretty clear from the rest of your accounts, that the dash m/kWh was much higher in your test, than for the "new" 2013 LEAF in the 2/24 test, and so the 2011 was reporting a much lower kWh battery capacity, as both LEAFs got an identical 77.2 miles to the VLBW, right?
Take a look at this recent range test by camasleaf comparing his 2011 and 2012 LEAFs:
I want my 281!

Where again, two LEAFs got substantially identical ranges but had a large disparity between the (more accurate than dash) nav screen m/kwh, 4.4m/kWh for the "new" 2012 and 4.7 m/kWh for the "old" 2011.
And now look at my range test results from last Summer, on a single LEAF which had the the kWh use report and all the m/kWh reports change over one year:
..I chose a day with very close to the original temperature condition, and drove the exact same route over the first 87 miles of the trip, using the same mode (eco) and used my original trip logs to closely replicate the same elapsed times for each of the three (same distance) legs of the trip.
The results from 8/30/12 were:
97.3 miles to VLB, 98.9 miles in total, by the odometer.
CW: 96.5 (~2.5% under-report) total miles, at 5.7 m/kWh, 16.8 kWh used from 100% to about the same capacity level, slightly past VLBW.
Compare this test with my first test on 9/7/11:
91.5 miles to VLB, 93.4 in total, by the odometer
CW: 91.1 (~2.5% under-report) total miles, at 4.9 m/kWh, 18.7 kWh used from 100% to about the same capacity level, slightly past VLBW.
Use CW report from range test to determine battery capacity

I think it is very likely both you and camasleaf are seeing the same thing I first did last Summer, a large decrease in reported kWh use (and battery capacity) over time and miles driven, that is
not showing up in a similar decrease in the actual driving range.
You, however, are probably seeing it with less accuracy, and noticing it much later, because you have not been using the Carwings kWh use report data, just less precise dash and nav screen m/kWh readouts, and may not have not been range testing your own LEAF on a fixed route, with controlled variables, over time.
