I just recently awarded a
+100 bounty to the user @Mark Bouchard. After the "day" ended I decided to look at his reputation graph to see the effect. To my amusement, the graph appears to predict his reputation up through October - what's more it seems to think he's in for a big slide tomorrow.
Please don't tell him as I'm planning to break the news gently - who knows how he might react after such an emotional rollercoaster.
