When you reset accumulated totals, it resets the miles/kWh on mine to 3.4! All the rest are 0.Where did you get that 3.4 m/kwh figure from?
(3.4 x 44.5 = 151.3 and we don't get a usable 44.5)
From what I've seen I'm pretty confident, that they have set it up on purpose so that when reset in Normal 3, at full charge/balanced it tells you the WLTP range of 163 miles.
It makes sense to do that, otherwise people would say why doesn't it state the range you've said when it's been reset (to "factory settings").
