I wish we could refer to long distance energy consumption concerns as range discussion and around home daily driving as efficiency.
Daily driving and errands mean a high number of initial cabin heating events. Where as a long trip might mean just 1-2 initial cabin heating events for a full charge.
I could claim a 70% range hit in cold weather due to Green Bay getting sub-zero combined with my 7 mile drive. I don't make that claim though because if I am using actual range as in worrying about how far I can go I am not reheating the cabin every 7 miles. On a long trip in single.digits I don't think I saw but a 10-15% hit.
People really want to figure out their theoretical range to make sure they made a good decision, and thus attempt to extrapolate from daily experiences. This goes poorly.
To the point of the OP, he should be accepting only submissions which are from single drives, and clearly indicated as such. The first couple responses in this thread were to the point, and then the thread got derailed by people talking about distance traveled between recharges, which is not helpful.
People need to define their terms extremely precisely.
