This isn't an accusation ... I am just trying to figure out why User 328857 's graph starts wildly fluctuating like a provisional player even though he's not. It happens after he leaves the site and times out in all his games. At first, it's a steady downward slope, and right after it hits around 1550, chaos ensues.

Originally posted by SwissGambitHe won a bunch of games after leaving the site. Tournament games time out automatically, he had some long timebank games against 1700+ players where they'd left the site before he did. For some reason the system was changing his rating by over 200 points for each of these games. Possibly they added some kind of system that makes inactive player's accounts behave like provisional ones to prevent rating inflation over the site?

Originally posted by SwissGambitYes I believe you are correct. It seems like the only logical explanation to the issue. I have wondered what caused this to happen on other rating graphs.
I think I figured it out. It's a problem with sorting on the graph. The games are simply in the wrong order.
All the games in the 'chaos' period finished on the same day. They apparently were all losses by timeout - even the ones where the graph goes up are losses.
