Below are my CW reports, available at the bottom of the "regional rankings" page.
Month and Year Grade Rank Energy Economy
May/2011 Gold 492 5.4 miles/kWh
Jun/2011 Gold 695 5.7 miles/kWh
Jul/2011 Gold 1651 5.3 miles/kWh
Aug/2011 Bronze 3622 4.2 miles/kWh
Sep/2011 Silver 3457 4.5 miles/kWh
Oct/2011 Silver 3640 4.2 miles/kWh
Nov/2011 Gold 2471 4.3 miles/kWh
These numbers need to be corrected for charge efficiency (relative to EPA m/kWh) but do seem to be entirely consistent with my driving, since I had the NTB11-041 CW update done on 8/3.

I think I can explain why the monthly results are not showing the approximately 5% reduction in cold weather m/kWh performance, I posted here:

I do a lot of my driving on mountain roads, and with both wet surfaces, and more driving after dark, my speed has often been restricted. Also, the (about 5%) lower cold weather total available battery capacity, has also meant that I need to watch the bars closely on some of my longer drives, and slow down. For instance, I used 18 kWh (CW report) for the 77.7 mile drive I made on 11/13, went from 11 bars to 1 bar, and got the VLB warning for the first time (when I wasn't trying to) since I got the car. I also haven't had to use the heater very much, other than pre-heating, which probably is not reported as "energy used" by CW.
Interesting that CW has moved me back up to "gold". Both a larger proportion of LEAFs now have probably now had the update, to correct CW, and weather has dropped others' m/kWh results, more than mine.
Happy Thanksgiving, to all.
