Strange Rep Count

Question

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.)

You hit your daily reputation limit:

You got a +2 from an upvote to since there was a -2 from a downvote. If something will take you over the reputation limit, then only as much reputation to get you to the limit is granted from it.
