We're saying exactly the same thing.

That a different distribution applied to the Age of Legends population as opposed to the Third Age population.

And I'm saying that the only way that RJ's "Bell Curve" description of channeler distribution can fit the facts as presented in the books, is if the Bell Curve he was referring to is the Age of Legends distribution, not the Third Age distribution.

Because, (to use the simplest possible example), on a Bell Curve the strongest possible channeler will be exactly twice the strength of the average channeler, and we know that it takes about 3 channelers of Moiraine's strength to match a Lanfear level channeler, therefore Moiraine cannot be higher than about 30 on the strength scale.

Hence the average strength channeler at 50 is almost twice as strong as Moiraine.

Clearly, therefore, all Aes Sedai weaker than Moiraine (which equates to about 99% of them) must fall under the lower part of the curve.

You cannot get away from that simple argument.

Hence the Bell Curve cannot apply to the modern day distribution of known channelers.
