I've developed a gut feeling that my range isn't actually 260 (264?) miles, so I've started to keep track of the stats. After long trips, I back-calc the range as:
[(Miles driven) / (battery % used)] / [(actual efficiency) / (rated efficiency)]
For example, in a recent trip, I traveled 112.2 miles, used 52% of the battery, while averaging 267 wH/mi. I back-calced the range as:
(112.2/0.52)/(267/240) = 240 mi
I've done this a half dozen times, and each time the calculated range is between 235 and 245 miles with an average of 240.
Has anyone else noticed this? Is the extra 20 miles range held in reserve below 0%?
