From TezLAB that tracks such things:

New in March 26, 2019 about 53,084 miles ago, it reported 240 miles. So this gives (227 - 240) / 240 ~= -5.4% range loss. Best of all, it looks fairly flat.
My understanding is the battery management system (BMS) needs a periodic min-to-max cycle to 'calibrate' the estimated range. I've not done it but there is a Gulf Coast casino I may take my good woman to while the water and weather is warm.
