In general I think you are correct (although we know the weakest AS is about 1/3 the strength of the strongest, not really a small gap)...

IMO run of the mill AS in general are rather weak in the grand scheme... but your range IMO is far too narrow. There is no possible way that Daigian can be stronger than nearly 40% of all channelers and be as weak as you place her. Personally I think AS span a range from about 15-45 (Daigian-Moiraine) with the vast majority in the 20-30 range. Note 4 women could hold the shield on Rand (which means Logains shielders were very weak indeed) ... linked they'd be about 80 (-10% for linking) assuming some were on the high side of average AS, but as soon as the 4th left the other 3 didn't stand a chance (they dropped down to about a 50 at that point).

We've only seen about 30 or so AS with Beonin level strength or higher (which seems about the level an AS needs to be in order to be a leader in the Tower), along with maybe as many more from the ranks of the other Channeling groups and only a handful between Moiraine and Lanfear, and that includes:

2 Damane (Alivia and probably Sera)

1 Kin (Garenia)

2 WF (Metaara and Talaan maybe a few more that I'm missing)

5 WO (Aviendha, Therava, Tamela, Viendra and Sommeryn)

11 AS (Sharina, Nynaeve, Egwene, Elayne, Bode, Nicola, Cadsuane, Meilyn, Kerene, Elle, Jancy)

and the 5 Forsaken women (not including Cyndane since she's kind of a repeat really)

If Moiraine is a 45, Cadsuane a 60 Egwene an 80 and Nynaeve a 95 it seems to fit that AS in general fall in the lower rungs of strength (with a few women that are outliers, and thus carry a lot of influence in the Tower. Egwene + R and L would be a 150 linked and as we saw with Alivia probably couldn't take down a FS Male due to skill differential, and may not have enough strength to cut him off from the source without some effort.

It would take 6 average Sisters linked to match Rand, but make even 1 of them weaker than a 20 and they have problems. 13 Daigians could probably overwhelm him by close to a factor of 2x.



I don't think the vast majority of AS are close to a 50, only the very strongest Sisters are close to that level. See my comments above.



I'd place Verin and Alanna at about 30 each, making them no match at all for Rand!



Liandrin is overestimating them IMO, if she's a 30 and the other 2 are 25 each they wouldn't even likely match her in raw strength ... much less skill as Liandrin soon finds out!



The Strongest sister out in the field was Nesune and I doubt she's much beyond a 35, linked with Daigian a 15 and Beldein who's what a 20 plus a boy who has just learned to channel? ... together they may equal 1 Forsaken! Flinn is considerably stronger, but he was linked with 2 middling sisters (20-25 each) which would map to equaling Demandred. Verin at 30, Kumira at 20 and Shalon at 40 plus the angreal seems about right to match Graendal.



If Amys is a 45 and Melaine a 35 that makes Egwene an 80, I don't find that hard to believe, we know Amys is at least close to Moiraine and Melaine "stronger than most AS" so probably at least a Myrelle or possibly Sheriam level.



I still chuckle that you quantify once about every 1000 years as "frequently" But see my point above about Rand's shielding. If a Strong FD is a 90-100 it would take at least 6 level 20 women to have a chance against him.



I've always thought this quote was out of place since Rand could not break a shield of 4 women at DW ... but if the 6 weakest women in camp (level 15s) were holding Logain's shield they may struggle and if you take that down to 5 he could feasibly have broken free.



I agree with this overall, I think we just disagree on where the weaker "highest strength channelers" fall on the scale... I can live with that.



3 Moiraine levels linked would equal a 120 ... perhaps enough to overwhelm in pure strength, but IMO you need at least a 50% strength advantage to easily cut someone off from the Source while they are already holding it. Thus Egwene smothered Sheriam without a thought, but Nynaeve couldn't do the same to Elayne.

But it would still take 3 Egwene's to completely dominate Rand level, as only then would they by 2x his strength.
