I ride mine mainly in 15/30 - I have that as my Trail setting. My Eco is 5/10 (for emergencies, or riding with analog bikes) and my Turbo is 100/100 for those times where I need a boost up a tough technical climb. I wanted an eMTB for a little bit of help. I had a FF for a few weeks, and then swapped it for an SL as it was too much power. Yes, I could tone it down, but it seemed silly lugging about a 25kg bike to ride it in Eco. I'm now on a 16.9kg bike!
I had the Gen 1, and rode it mainly in 30/80... which to my legs felt about the same as 15/30 on the Gen 2. It also works out at about the same battery efficiency over the same routes, so they must be close.
Last weekend I was at a local trail centre, and had 2 RE's with me. I set the RE to run out first, and used Microtune to set the bike to 70 for the long slog of a climb. I then set it back to my Trail setting for coming down. I did this a couple of times, then swapped out my RE's and carried on. Once the 2nd RE was nearly dead, I unplugged it and used the bike battery.
I did 22.5 miles, but over 5000ft of climbing. Both RE's had about 15% left, and my bike was at 33%. My legs ached the next day!!
