What happens is, often the PTO's sanction a new tournament for a separate division either right before or after the event. Then they upload the TOM file for that tournament. Eventually the Pokemon.com site will recognize that new tournament as a Premier event, and it will appear on the list that I pull results from. It's not a manual process on my end...so I have nowhere to stick those Jr and Sr attendance numbers yet.
UPDATE: just re-ran my import, and the two other Washington tournaments are appearing now.
