Hey Mike, PDGA might give you a rating for GPB and PSO. I know when I first signed up it was after my first tournament, but they still based my rating on it.
You will probably be rated with the December update.
Good point Job. Mike, if the events you played go official this year and you still don't get rated from them you can always email the PDGA and have them added. They still keep track of all that because you paid the $10 non member fee.
