Metaara I think is the name you are looking for.



So in approximately 12,000-15,000 women who can channel (6k WO, 2k Kin, 2k AS and Novices etc and anywhere from 2-5k WF and Damane) we now have 4 women (Egwene, Elayne, Avi, Metaara) at this level plus 7 (Alivia, Sharina, Sommeryn, Nynaeve, Talaan, Tamela, Viendre) higher and the 5 FS. Even if there are another 10-100 women at this level it's clear that Egwene level is extremely rare.

And as an aside, we don't actually know that Pamela and Vienre are in fact stronger than Elayne in total potential. We know that they are currently stronger than she and Aviendha, but neither of them have hit their full potential so they may only have been stronger than them at that moment. In fact we don't even have conclusive proof that Someryn is stronger, only that she's never met a WO who has more strength than her. We have no evidence that she's even met T&V!



Then why does Cadsuane work so very hard at building her reputation? Yes there is a good difference of strength between her and the next levels of AS, but not so much that she doesn't have to go about working toward having the AS around her be in awe of her in non-strength related manners, Alanna was even ready to challenge her over Rand.



But we also know from Elayne's POV that she is close enough to Nynaeve to be willing to disobey her, if Nynaeve was dramatically stronger she would have never even considered that! We've also seen that Nynaeve wasn't enough stronger to cut Elayne off from the source once she had embraced it. If she was vastly stronger a poorly woven shield wouldn't make that much difference.

And aside from Aliva, Nynaeve and Sommeryn no FS has ever even noted the strength of any female channeler aside from Elayne (or another FS level woman), seems to me that they'd need considerable strength for Moghedien to make something of it for no reason. Clearly (IMO) Elayne's level is much closer to the FS level than the rest of the field. I'd say at full strength they no more than 10% below the FS.



But we know neither angreal was particularly strong, and linked sisters are slightly weaker than the combined strength of each AS.



I think that quote from Moiraine is mostly hyperbole. If you look at the context it has more to do with the political ramifications within the Tower than with their actual strength potentials. Not to mention how often Moiraine's estimations were dead wrong.
