How far can my electric velomobile go - a range test of three different levels of e - assist.

I set out on some test rides to see how far I could ride at three different levels of assist. I rode until the battery level display started to indicate that the last of the battery was almost depleted. I expected to be able to ride a little further as the assist level lowered, and that my rides would prove this. I know that there are many things that affect range, but I figured since most things in each ride would be the same, the rest would not make to much difference. Five key things that were more or less the same in each ride were as follows: 1. Rider (me), 2. Velomobile (my DFxl), 3. The road surface (same route), 4. Luggage, and 5, Effort put in by me (relaxed effort). It is very difficult to say how far my e-assist lasts, as there are so many variables. For example in the video I ride 50km at max assist when the battery has been almost depleted, but I rode 92km going the opposite direction on the course (a slow downhill gradient made a difference of 42 km). Well I hope you enjoy the video, and I hope you put in a comment on what sort of things you think are variables to consider when explaining range of an e-assist to someone.
