You cannot say Egwene, Lelaine and Romanda need to match Rand's RAW strength to equal him, while Lanfear simply needs to meet his effective strength to equal him.

So you say Rand has a raw strength of 500.
Then you say Egwene + Lelaine + Romanda = 320+200+200 = 720. That's 50% stronger than Rand. Even if you take 10% off for the linking loss, they're still on about 650 vs. Rand's 500.

And then you still have to take into account the females dexterity advantage, which means that in terms of EFFECTIVE strength, Rand is only a 400 on your list. Therefore, you have Egwene, Romanda and Lelaine on 650, an Rand on 400. They would totally destroy Rand or any male channeler if that was the strength difference between them.

In fact, even if you just took Egwene plus Romanda, that would equal 320+200= 520. Take away the 10% linking loss and you're sitting on 470 EFFECTIVE strength. And due to the males dexterity disadvantage, it means that Rand's RAW 500 is actually equivalent to only 400 on the female scale. Meaning that Egwene pus Romanada on 470 are 20% stronger than Rand.

You are inconsistent in your application of the data, in order to MAKE your list fit the evidence.

How can you say Lanfear on 400 is comparable to Rand on 500 due to her dexterity advantage, but Egwene, Romanda and Lelaine need to be compared to Rand's RAW strength, with the female dexterity advantage suddenly ignored?

The bottomline is that if it takes Egwene plus Romanda plus Lelaine to match a male Forsaken, it should take Egwene plus Romanda plus Lelaine to match Lanfear as well.

And since Egwene plus Lelaine plus Romanda are around 700 in strength, together, they are vastly stronger than Lanfear who is on 400. This is not supported by the evidence in the books. In fact, it contradicts it.

Instead, you should put Egwene at around 50% of Lanfear's strength, and Romanda and Lelaine each at around 30% of Lanfear's strength. That would make everything fit perfectly, because then Egwene plus Romanda plus Lelain would - on the 100 point scale - equal 50+30+30 = 110, and after the linking loss they would be very close to Lanfear's strength.

On your strange 400 point scale, you then multiply the above by 4 to get to 440 vs Lanfear's 400, and after the linking loss you'd be at around 390 for Egwene's circle vs Lanfear's 400.

THAT fits the evidence. Not a scale where Egwene and Moiraine/Lelaine/Romanda are vastly exaggerated in strength as you are trying to claim.
