I posted this in the most generation RNG helpthread before I noticed the 5th gen rng help page.. so i will c/p it here. a mod can delete one if they feel it is necessary, my apologies
Here is my problem. I am playing Pokemon Black, and am currently trying to RNG a shiny Woobat
I am using a Synch and have it as my lead. I am doing the proper  keypress and starting my game at the correct time (as I start it 1  second before and have RNGed non-shiny pokemon) and my Timer0 is  correct. There are also not any roaming NPCs (I am in Wellspring Cave).  My Shiny Frame is 58, and I have 2 Chatots, I go back and forth counting  to 58 chatter cries and then use Sweet Scent. If I find a Swoobat, it  is not shiny and does not have the desired IVs. Can anyone help me  determine what the issue might be?
