For fun, after looking at my ranking (769) after only posting one game, I decided to see just how far along on the ladder I was. So I brought up the ranking page and skipped to the very last player (1140-odd).
The player in dead last managed to play 4 games and only score 8 points. I don't see how this gets done without retiring in 5 turns or less. I just found it amusing. Normally if I retire a game, it's normally to see what kind of pointage I have at that particular turn and I've never had less than 300 points on that screen. I just don't see why anyone would do that.
