It seems that it is ever so slightly possible to break the reputation limit, or I am misunderstanding something. Here is what I think happened:
- I hit a daily reputation limit from upvotes only. (+200)
- I received a down vote. (+198)
- I received another upvote (back to +200)
- The existing downvote was removed, so I got credited +2
From my reputation tab:
So we see 277 rep. Answers don't count against your reputation limit, so if we factor those outwe do 277 - (15 *5)
= 202. So it looks like I got 202 points from upvotes.
