I've never gotten out of a single round in any kind of tournament. Not even a banded one. One particular tournament woke me up to a problem. In the first round of a banded tournament, I was in a "foursome" and every one of the other players either was....or was recently, several hundred points higher.
I would have even won this years Automn 1300-1399...coming in second to a guy who is now rated over 1600. He WAS rated over 1600 before timing out more than 25 games.
I'm usually in the 1300's....but I have at times cracked into the 1500s (and then get smakced right back down). BUT, my rating falls because I play and LOOSE...not becuase I time out or resign a bunch of games.
The "30 day window" is not enough to weed these guys out.
