One of my problems is that where I live in the Santa Monica Mountains there are lots of elevation changes. During my gentlest run, which I previously reported, there was an elevation change of about +450 feet over 12 miles and I drove over slightly rolling hills. I suspect the "up to 15 miles" (or 35-37 kms) range is tested where the elevation does not change.
Yes I made sure it's electric only, in fact was monitoring on status page. Got warning and heard engine turn on. I did an almost perfect loop (same start/end) so net elevation change was 0, but was climbing and descending. Next time I'll log elevation but in guessing from my experience with my leaf logger that I have +/-200 ft delta. That's why I want to find a better course.

In fact I'll repeat loop with leaf and use the logger app and report back.

Final note: estimated range dropped to -- (no estimate) and I still went 2 miles before engine turned on.
