Sorry for the incredibly late response; I haven't been on Smogon in forever.
Anyhow, the only RNGing I've done in B/W so far is C-Gear Reshiram (entry-level). I've been doing other stuff in Emerald, like replicating Negator's Latios and stuff. I can read over the standard RNG/Entralink stuff and give you a rough interpretation, but I can't promise that I'll know the answers to everything you ask.
