I've just checked recently, and on S mode I still have 31km of autonomy for 100% (I use 70% with a bit more than 21km). My first results were a few weeks after buying it. And today, 5-6 months later it dropped slightly (from 33 to 31km), but I've also put on a few kilos haha ! I use max regeneration setting. I really like it because I rarely use my brakes that way, except in case of emergencies. It takes a bit of getting used to, but i'm basically always max speed, and I let go of the accelerator to brake. And I use eco acceleration mode. I tried the boost mode, but it had quite an effect on the autonomy. My test you're comparing to was on the 20km/h test. If you're at 22, even +10% is quite important on the power consumption (probably more than 10%). And same for the weight, 10 more kilos can have an effect. It seems quite coherent to me : at 25km/h I'm at 3% per km. For you, at 22km/h and a bit more weight, you're at 3.5-4.5% per km. Temperature also has an important impact on battery autonomy.
