I'm not even sure how to calculate our deg! Same, 2018 3 long range. I think they advertised it as 305mi but some time later increased the capacity of the car to 315mi; I max charged it to 314 once but never quite saw that 315. I think we're around 273 as max now so 89.5% of the original quoted life, 87% of the "updated" life. Car has 115k miles, ~ 185,000km.
