Paizo has dipped their toes in sactioning Adventure Path material for PFS credit. They are starting with the RotRL Anniversary edition and the current Shattered Star APs. You can check out the announcement here: http://paizo.com/paizo/blog/v5748dyo5le7p?Sanctioning-Adventure-Paths-for-Pathfinder
I need to do a bit more research but I think that our Saturday game may qualify for credit under the following in the announcement:
"Alternatively, if you are participating in a Pathfinder Adventure Path with an ongoing home group undertaking the entire campaign, you may receive credit for playing the sanctioned portions of the adventure as if you had played a pregenerated character. In this case, GMs running the Adventure Path are not bound to the rules of the Pathfinder Society Organized Play campaign when running the campaign or the sanctioned portion of the adventure. Pathfinder Society characters and characters from an ongoing Adventure Path campaign may not play in the same adventure."
I believe that this means that I can give you credit that you can apply to a new pregen. More information to come.
