S 70 delivered 11-19-15 with 90% charge reading 210 rated miles. Every subsequent 90% charge yielded the same 210 rated miles. Suddenly the most recent two 90% charges have read 217 and 218 rated miles respectively on the charging window of the 17" display and on the dashboard display. Both of those charges were after the most recent ver 7.1 update. Total miles now is just over 2,000. Wh/mile since last charge, as displayed on the instrument panel, is running just under 290 in mixed city streets and freeway driving with TACC set to 70mph. Did Tesla change the SOC algorithm, perhaps using the car's recent average Wh/mi history instead of EPA rated usage? 218 miles at 90% equates to 242 miles at 70 kWh full charge.
