After our S 100D was delivered, we were getting about 307 miles of range at 90%. After a software update, that dropped to 301 - which has held steady for several months. We took a 600 mile road trip, charging at superchargers, HPWC (48A) and for an hour on a J1772 (40A). Now the 90% range has dropped to 297 miles - losing about 1% after the trip - and this time, there wasn't a software update installed to explain the difference. Has anyone else seen this?
