Playmaker, WGT has to verify all the scores before they issue winnings... sometimes it takes days, sometimes it takes longer.
They need to weed out the liars, cheats and thieves who have more than one account. If they can get a couple of them ahead of you, you could actually place higher than you thought.
Patience, though... the only time you don't want them to verify your score is if you are one of the people they are going to disqualify.
