Let me rephrase that. You don't have to be lucky that you encounter whatever Pokemon you want, you just have to be lucky enough so that whatever spread you need is located on that encounter slot, which as I said below, involves plugging in every seed that PokeRNGDP gives you into RNGReporter. Here's the rest of my procedure. When I have my list of seeds, I go into RNGReporter and limit the constraints to ==31,31,31, none, ==31,31, chose Method K (for sweet scenting), then plug in each seed and hit Generate. If the spread appears (sometimes it doesn't for various reasons), right click on the spread and choose "Encounter Slots." It'll show you what encounter slot it appears at with Sweet Scent, and there's a link that shows you which Pokemon show up in certain encounter slots in every game. Make sure you're on the bike, then advance to the frame prior to your target, sweet scent, and voila.
