So, unplugged from work today with 155 rated miles charge  at 3:55 pm today. I went to the gym near by, drove on home. I just checked my app to see what my current charge was (just being bored and plugging thru the apps on my phone) and noticed it was at 154 rated miles  . I thought to myself: "thats odd, im almost certain i left work with 155, and i drove about 5 miles since then." So I then proceeded to go check my car to see if this was just an app screw up or something weirder  . TL : DR: drove 4.6 rated miles yet only dropped 1 rated mile on my charge. Anyone have any ideas on this? Product of the batteries balancing themselves, perhaps?
