There might actually be something else happening to RaVeNLoRD here...
I checked my own stats, and even with a ~65% win rate, my split is only 880 games in first position, and 909 games in second.
A quick look at WW's stats shows a 4727/4755 split, but his win rate a bit lower at 60% since he matches mostly (exclusively?) against high level opponents.
RaVeNLoRD on the other hand, has a win rate pretty close to 50%, but is still playing from second position a disproportionately large amount of the time.
My expectation would be that the higher your win rate is, the more games you would have from second position. It is possible there isn't anything going on, but the numbers make me wonder if RaVeNLoRD is somehow logging out after every game, putting himself back in the Winners pool even after a loss. I vaguely remember a thread where another forum member had this issue.
