Oct 8th 2008 4:52PM Maybe one of his arena partners was coordinating the win trading, and he was carried along for the ride?
Maybe he was tanking his rating intentionally just to power-through a few games at the lower ranks (possibly with an extra guy in tow for the personal rating jump). That looks like intentionally losing a bunch of games to a team, then beating that same team a bunch of times. Unintentional win trading.
