I'll be honest, I stopped reading after that sentence. You are wasting your time. Game Freak completely screwed up the breeding mechanics for egg generation in B/W2 so RNGing one is, for all intents and purposes, impossible. If you want to breed flawless pokemon, RNG on B/W instead.
If I missed something important in the other information, just repost after you try some B/W breeding.
