Okay, usually I don't like "what's going on with my rep cap" questions, so sorry for this; things just don't seem to be lining up for me today, though. There were service problems earlier, which makes me wonder if something out-of-the-ordinary is going on, even though MSO was reportedly not affected. My /reputation results:
2 67012 (10) 2 67071 (10) 2 67040 (10) 2 67071 (10) 2 67071 (10) 2 67012 (10) 2 67071 (10) 2 67039 (10) 2 67071 (10) 2 67071 (10) 2 67039 (10) 2 67071 (10) 2 67071 (10) 1 66934 (15) 2 67039 (10) 3 67143 (-1) 2 67144 (10) 1 67144 (15) 2 67144 (10) -- 2010-10-09 rep +189
Sixteen upvotes, two accepted answers and a downvote do equal 189 rep, which all told is still short of the cap value, 200. Without the accepts, that's 159. There are no square brackets in my rep report, and my rep cap was reached via rep from upvotes *only* on x days counter didn't go up. So, no sign of hitting the rep cap.
The envelope page does shows signs of capping. In short, the two rep lists don't sync. I did click on "reputation" and "today" manually. Individually, the tallies on the two pages do add up correctly. As far as I know, nothing of mine — at least, nothing that received votes — has been deleted recently. What's going on here?
EDIT:
This appeared a few minutes ago. The "hit cap" counter went up a tick, too. Maybe caching is to blame? It's looking more like Ether's answer is correct.
