When I bought my 2014 P85 August of 2017 with 65K a full charge was 256miles. 25months later and 90K on the clock a full charge was 247miles last month last I tried. At one point I was doing very shallow discharge and 80-90% limit and 100% had fallen to 242miles, letting it run way down and filling back up a few times allowed BMS to re calibrate.
