hi there, i'm a new (<2 week) owner so still very new to the amazing Model S experience. i've been tracking my daily SOC for a variety of reasons, and noticed that my morning SOC is typically ~3 mi of rated range lower than where i left it after my daily commute home the evening before. in other words, when i park in the evening it might read 203 mi rated range, and the next morning it would be 200. is this simply due to the ambient temperature? the temperature differential is on the order of ~15 degrees lately (i.e. 70F in the evening, 55F in the morning). note that i don't plug the car in most weeknights since i charge at work. i'm not concerned of course, just trying to be appropriately educated. thanks!
