:) You're right, of course. It's simply a thought experiment. The top one percent of Sykers...

Country of a million souls, 2% (20,000) are Sepcarim. Divided by three (if we assume rates of Monk, Shaman and Syker are roughly equal, which hasn't been discussed, as far as I know), we get 6,500 to 7000 Sykers in all. The top one percent of that? 65-70.

How many in that group are skilled with mental manipulation en masse? It only takes one.

EDIT: It isn't unreasonable to imagine a group of less than a dozen in the entire world, all attempting to out-plan and out-predict the others.
