welcome to AZ, Sorry I cant help you with the APA rules, but you will get your answere here for surre, there is more information here than you can imagine, i been a player for 25 years and I still learn things here everyday, I learned more here in the first couple months than I did my first 5 years in a pool room.
if I can help feel free to contact me here,
Best regards,
Eric aka Fatboy(I'm not that fat, its a old nickname since 86)
