The bonfire quote can obviously not be taken literally, otherwise Nynaeve would be hundreds or thousands of times stronger than Egwene. It does indicate that a big gap separates them, but if one considers that Moiraine spoke the statement, it's really no surprise at all. The key to these statements is often to look at who spoke them... Reanne's statement on Alivia's considerable advantage may not be so considerable considering Reanne would use herself as the standard. By the same token, Graendal saying that someone is 'not negligible' implies that the woman is incredibly powerful because of Graendal's own innate power.

If Nynaeve has a strength of 95, Egwene 70 and Moiraine 30, then we can see how immensely powerful Egwene is. Aes Sedai have hardly ever known someone to be twice as strong as some of their most powerful members. Now imagine Moiraine finds a woman who has almost her whole strength on top of Egwene's. That would certainly be a massive discovery and worthy of 'bonfire'. Everything is relative.

I obviously don't agree with Shannow's post below. In my opinion he takes far greater liberties with OP strength assumption and then goes further and labels them as fact or logical deduction. For instance, although RJ said that Egwene is between Moiraine and Nynaeve, he never said it was linear or part of some grand scheme to make all things equal. What is most likely is that he has categorized the channelers into Forsaken, Strong channelers and Aes Sedai.

One can take any statement and label it as fact. Take for instance, Moiraine's statement that Egwene and Aviendha could match one of the Forsaken together. 'Logically' one could assume that they have a strength of 50 because 50+50=100, but one need only point out the following points...

1. Moiraine is often wrong about the Forsaken.
2. Who is she comparing them to? Ishamael or Moghedien?
3. Alivia really is high Forsaken strength, and with a strong angreal she was on equal footing with Cyndane. Therefore for Egwene and Aviendha to match one of the Forsaken females they would need a strength of 150 or more. Therefore 75 is a more likely strength for Egwene/Aviendha. It also implies that Moiraine thinks that the two can overwhelm a highly trained and super-strong channeler, meaning that Nynaeve is probably considerably weaker than the two of them combined, thus once again suggesting that either channeler alone is not massively below Nynaeve as suggested, but certainly one level below. Therefore strengths of 70 and 95 are more than reasonable.

I don't know why anyone would come here and suggest that their list is fact when all but one statement in the series can be refuted regarding Forsaken strength. If I decided in my mind that Mesaana is second only to Lanfear, there is not a single quote in the series to contradict me.
