I can recall multiple posts reporting on ranges far longer than LBC-projected at higher speeds, as well."RegGuheert"
...Ed's long-distance drives at very slow speeds tell us that much of the capacity is still there, but is is not available to those driving on the highway...
I suggest (those who can) actually test that fraction of the available capacity, matching all the conditions of any one of the 70 mph AVTA LEAF tests as closely as possible.
The higher the speed, the less any efficiency changes your LEAF or its tires have experienced should have on the results.
At the lower speeds I drive, the range loss is considerably less than my pack's available capacity loss, evidently due to lower rolling resistance (tread wear-adjusted) of my replacement ecopias, and/or a reduction in drivetrain friction from when I began range-testing, at ~3k miles from new.
BTW, in addition to your suggestion that the LBC may allow a lower % of access to the total capacity when driving at higher speeds, it is also entirely possible (IMO) that actual cycling efficiency (or, perhaps just discharge efficiency at high rates/high speeds) decreases as the battery ages.
There is an old discussion on the Volt thread RE the apparent decrease in discharge efficiency from AVTA data.
