Not sure if it will correlate or not, but at Caesar's Indiana, the 340 event attracted about 700 players...500 plus approximately 200 alternates who were brought in as others dropped out. I would register early if I were you.

As to quality of play, at my first table there were maybe 2 donkeys, 6 average, and 2 really good players. You don't have a lot of time to get going so if you don't catch cards in the first 2 or 3 levels you should start getting more aggressive. Hope this helps and gl.
