The GNC splits have already been posted to the GAOC site - see

In my opinion, when a club is finished putting on an A-meet, they should post the results/splits on their website, hopefully, in a timely fashion. In my opinion, GAOC did this. They are not obligated to post them to AttackPoint.
Since I had access to the files, I have posted the Green, Red, and Brown (the courses which had a number of AP members participating) to AP.
