So I've had my MBP over a month, and after 36 cycles, my battery health was down to 97%. Decided it was time for a calibration. Charged it all the way up, ran it all the way down around 11:30 PM last night. Let it sit for way more than the required 5 hours, until about 11:30 this morning. Sleep indicator was not flashing, so I knew it had worked. Connected the battery cord, booted her up, and I saw what you see attached to this post. A reboot later and everything seems fine--but should I be concerned?
