The reason I found your CW results interesting is that your driving/charging/climate conditions contrast so strongly with my own. You drove in level city traffic, I drive at almost all higher speed on open roads, with frequent large ascents/descents.
Temperatures here were 25 to 55 degrees most of last week, here in far-North California. I usually charge to 80%, during the coldest part of the night (PG&E off-peak rate) and on all my long range tests so far, I have also topped off a "cold" battery, previously charged to 80%.
So while your CW reported kWh use indicated about 22 (?) kWh available to "stop", my numbers were about 20.4 kWh under mid-60 degree F ambient temperatures, and 19.4 for a top-off done in the mid-30 degree range. Both my available charge estimates also have a greater uncertainty, as I finished driving with higher SOCs, and had to extrapolate further to "stop".
I plan to try a long (to heat the battery) 100% charge at higher ambient temperatures as soon as weather permits, and sometime in May or June, I may be able to try a charge at over 100 F, and, perhaps, even exceed your 22 kWh?
I don't think high or low regen levels themselves can be considered good or bad unless the type of driving is taken into account. It is always preferable to use regen rather than friction brakes to slow your car, but it is also preferable to avoid regen whenever possible, as those kWh cycled through regen are reduced by an (unknown) efficiency loss.
In traffic, you have to decelerate frequently, and so higher regen is unavoidable. What your high levels of regen, coincident with record range, do seem to indicate, is that LEAF regen may be more efficient than most have guessed, and possibly also, that available battery charge is quite variable, due to temperature, and/or other factors.
Of course, much of what is above is dependent on CW being consistent between vehicles, which is unproven, at this point. So I hope others will continue to post their observations. I wonder if newer cars, like yours, could even have another CW update, which Nissan hasn't deigned to announce.
Please post your odometer/CW miles driven accuracy test results, when you get them.
