Looks like there's a new schedule and they somehow figured out how to add 26 more slots. Originally, they were going to take 1008 players (72 x 14 courses). Then they juggled schedules and eventually hit 1099 for a while. Now the total slots stand at 1125, if my math is right.
They added mostly juniors (18), pro seniors (4), and pro master/grandmaster women (4). Interestingly, there were two former world champs on the wait list and now, magically, there are enough slots to accommodate them. Cynics might say there is no registration deadline if you're really good, but I'm sure this was just a happy scheduling coincidence.
