Charging Over Night

I was wondering if others have seen the range decrease over night while plugged in? For example yesterday before bed I was at 241. I kept the car plugged in and woke up with 233 miles. Anyone else see this?

A software update a month or so ago gave the S similar topping-off behavior as the Roadster: it wakes up every 24 hours and tops off the battery pack's charge. Before the latest 4.0 release, your behavior was normal: vampire loads would suck about 8 miles per day of range. Now, with 4.0, the car shuts off its displays and such when you exit the vehicle and the vampire loads are expected to be much lower. I haven't let it sit for long enough since 4.0 was installed to know: a) how much smaller the vampire loads are, and b) if it still wakes up every 24 hours to top off the charge.
