Estimated range is a rolling average of the last 18-miles or so. It does not 'learn' your long-term habits, it only bases the range estimate on the last chunk. So, your short trip to move the car likely tried hard to bring the cabin up to temperature this time of year, and especially if you have a REx, all of those heat watts come directly from the battery. So, a short trip could suck up some watts. Batteries can flow more of their power when they're warm...so, your results are likely to change once the ambient weather rises.
Note, since the car does not know where you WILL be driving, or how you'll do it, your future results may not represent what happened last. Say you previously were driving on the interstate at a good clip, but your next trip is stop and go in the city...your estimated range will be way off.
