So today I noticed that one of my answers had gained a strange amount of rep (+17). I checked it out in my profile, and saw that it had gained 15 points from being accepted and another 2 from being upvoted.

Now, I've never seen any scenario where one of my answers gets accepted and upvoted, but the upvote only counts for +2 rep. What is this? (Sorry for any incoherence, I'm pretty tired.)
