Well he did say in separate quotes that the strongest possible woman can do what the strongest possible man can to the same degree in general. He even said that in fight it would be equal.

It's potentially a mess. Remember that 100 represents a male channeler of ++1 or a female of level 1. It doesn't factor anything about flow strengths. At the same time flow strengths haven't been well elaborated on. Egwene is perhaps a great example of female extreme strength in Earth, but how does this compare to Ash'aman strength in Earth? My guess is that the males mostly have her level of strength in Earth, it's merely been elaborated on in her because she is a main character. For instance, Naeff is one of those rare men strong in Air and it seems like he holds himself on the level with a woman to the point that it makes no difference. It's not like Aes Sedai are watching him in awe.

Most channelers are strong in about two flows. We have seen Moiraine struggle with Earth and Fire, but she's strong with Air and Water - but does this mean that she is strong in those two or average? The men will be the opposite, which makes me think that effective strength will be a male using Fire/Earth/Spirit to get what he needs and a woman using Water/Air/Spirit - which is why the two sexes aren't directly comparable.

Therefore I think two theories are possible. It's possible that being strong in more flows can raise your effective strength. Maybe Egwene's effective strength is 95 if she is strong in all the flows, but I don't think so. Just because she can use anything easily doesn't mean she's stronger - a male or female of her power will merely find another way. The task at hand will therefore be completed either way.

It's more likely that 100 really is 100. I've never seen a strong channeler struggle with any flow. Rand uses Air and Water liberally and without issue. Alivia's first flow against Cyndane was Earth, and both Cyndane and Lanfear used Fire as their primary attacks. It seems like a minor issue to major channelers. I suspect strength in the flows becomes more important when it comes to small tasks rather than large ones.

Talents should be ignored. By definition they are rare and cannot be used to gauge effective strength, unless as you've done, you make a Healing strength table, but there's not much point to that unless you're hiring people for the Yellow ajah. Asmodean's statement about Semirhage and the weather implies that all channelers are good at things and bad at things. Even Rand can't Heal well. Therefore it's an equalizer, so Talents should be discounted.

It's possible that someone like Demandred could have an effective strength of 120 because of skill and practice. LTT and Demandred seem to be totally out there compared to other people even from their own Age. There's no doubt that Alivia could be defeated by weaker channelers.

Well as I explained, maybe not so much. It seems that if you are reasonably trained and your strength is 100 then you are probably at 100 effectively. Talents aside, it's unlikely that someone being strong in other flows could be better. A woman weaker than Rand can make a bigger Air bridge, but he can probably perform other feats that Lanfear could not. Therefore it's understandable that RJ roughly equated them. It's likely that a good mixed circle of two is so much better than even Rand.

As I said, I don't think so. Considering most women are strong in Air/Water, I don't see how their effective strength increases if they are suddenly strong in Fire/Earth unless it comes down to fireball throwing, and even then a normal woman can throw a big fireball, it just takes more concentration. To measure channeler effectiveness you would probably have to take Semirhage and Rand and make them do twenty things with the Power. Rand would exceed Semirhage in 10 and vice versa, but both could do better than what their respective sexes could achieve, so they get 100. Talents aside of course.
