My (75 kWh MS 2017, December 2016 build) only gets around 236 miles on a 100% charge. And gets around 208 miles on a 90% charge.
The car only has 28,659 miles on it.
Well it beats mine. Mine is a 2017 September build (newer than yours, mine came with HW 2.5). I would get 219 at 90% when new. I get 205 at 90% now. I've done those recommended "recalibration charges" with no change. There was another thread about a month back with other folks with the 2017 S and similar numbers.
