The info on this post contradicts what Terez read in the notes. Per those notes, Daigian, the weakest AS, is level 45/33, not level 72/66. I think this entry has a mistake, in that it says the 66 original levels were for Aes Sedai only. I believe it included all channelers, even Morghase and Sorelia.
So would be sorely lacking. Setting aside largely irrelevant types like Morgase/Sorilea who can barely even briefly rarely GRASP the Source, much less DO anything with it, many people too weak to be AS still have sufficient strength to actually USE the One Power. And any One Power strength scale omitting people who demonstrably HAVE such strength is incomplete and thus inadequate.
Such people are wilder scum and not worth taking into account. For practical channeling purposes, RJ could always have them do what the story called for, like the Kinswoman with a Talent for shielding. Note that Elayne made no mention of the specifics of the Windfinders' strengths, except for those who approached, equaled or bettered her own. Little literary touches like that means there was no need to apply the scale to anyone but the sisters, since they were the only ones to whom it was important, and the handful of non-sisters who stuck out, like the Forsaken, or Someryn, the Aiel godmothers & Aviendha or the top Windfinders.
WoT is about how people behave and react to things. We didn't get a whole of specifics about insane male channelers, because the important thing in the story is how 3,000 years of insane or trouble-making male channelers, plus an apocalyptic cataclysm, have made people view men like the main character. The relative strengths of the channelers is only important for the way it affects characters' interactions. When it is not going to affect those interactions, there is really no need to apply the scale.
