and again this post explain what pokemon will appear http://www.smogon.com/forums/showpost.php?p=1821938&postcount=5Question about RNG captures. When you do hit your delay and advance the frame to your target, is there a way to know which pokemon you'll encounter? I'm currently trying to capture a Swarm pokemon (Cubone). Do I have to keep hitting my delay/advance frame/Sweet Scent until I encounter a Cubone?
encounter slots determine which pokemon will appear for which frame in a certain area. To view them input the seed your using into RNG reporter's main menu, the IVs you want click generate. Then find the spread you want with its corresponding information right click and an option should appear that says " calculate encounter slots"press that and it should give you the encounter slots for sweetscenting.
