I'm considering RNGing a gastly in Sprout Tower. I've read on one guide (
http://www.smogon.com/forums/showthread.php?t=78139) that sweet scent frame advancements are inconsistent when a pokemon is behind you (and you can't get on your bike inside). I'm curious what precisely is meant by "inconsistent."
Let's say I hit my seed and advance up to where an advancement of 1 is needed. Let's imagine sweet scent advances more than needed, perhaps advancing by 2. If I hit my seed again and then stopped a frame short and then sweet scented, would I be sure that I hit my frame? Or does this "inconsistency" mean that I could get different frame advancements depending upon which frame I'm on (such that I get an advancement of 1 when I need 2). In other words, does this inconsistency mean it is possible to get a situation where it is impossible to hit your desired frame because it either advances by 1, or 2, at precisely the wrong frames?
