Sorry, I thought that at first too, but that is wrong. The "overnight" drop is visible as a small vertical jerk of about 1% difference in the "Battery State of Charge" graph right after the 300 miles mark. That's why in my account I have the "expected around 90, saw 50 in bad lighting, misread it as 90" snafu. There is a drop, but not as precipitous as it seems. What happened at 400 miles is apparently a set of full stops as he pulled in to a parking space to talk on the phone and say "I'm not gonna make it," followed by a short reversal of highway time which ends on the 400 mile mark as he went into Norwich, followed by a lot of stop-and-go driving in Norwich to get to some Tesla charger which the NYT article says is around here: http://goo.gl/maps/cgctM http://goo.gl/maps/cgctM I can somewhat imagine his impatience and wish to get going again, if that's the situation.

No, I think overnight was at 400 miles. The Milford Supercharge was at roughly 322 miles according to the graph. Broder says he traveled 79 miles before spending the night at Groton, so that's at roughly 400 miles.

Sorry, no. The original NYTimes map makes it very clear the Groton overnight stop (point ⑤) is at the 399 mile mark (114+133+73+79): http://www.nytimes.com/imagepages/2013/02/10/automobiles/10tesla-map.html http://www.nytimes.com/imagepages/2013/02/10/automobiles/10t... And, the points on Musk's graph at ~399 and ~401 very closely match the reported night-before (90 mile) and morning (25 mile) range readouts. The big drop, almost like a charging straightline in reverse -- is at mile 400. Some have suggested it's the battery's own self-heater which prevents it from getting too cold; that makes sense, but I'd love to see an official Tesla reference to that effect, if it's sufficient to explain the charge drop.
