Well those are direct quotes too. How about a new tactic where you don't call people moronic for recognizing verifiable quotes in the series? Logain has been at the BT - he knows that gateways size is linked to strength, which it is. This was a theory that was put into place for most of the series, and confirmed by Logain. It's also not like Logain was beaten to death by everyone around him when he made this 'moronic' statement. It's clearly true.

We have seen that Rand is the strongest channeler in the series and he can also make the biggest gateways at 4x4. Then there are channelers who are slightly weaker than him like Sammael and Osan'gar who have smaller gateways. Not only this but Rand himself has used gateways size to see how his Ash'aman are growing in strength.

Considering Asmodean thinks that two women together equal a man, I think we can take much of what he says with a pinch of salt. That said, it seem like gateway size is linked to your strength in the Power, but not the amount of saidin/saidar you put into it. Your mind probably grows in strength as you grow with the Power, and this allows you to handle it without burning yourself out - and so it's probably this factor that determines gateway size. It's likely that Rand puts in as much strength to make a gateway as an Aes Sedai does to make hers, but his strength in the Power passively allows the size. I'm pretty sure that the ++1's can all equal this and that the ++2's are a little smaller etc.

Then there are also factors like strength in Spirit and even Fire in men, as well as the Travelling Talent that Androl has. Androl is rare enough that he draws looks from people because he is so weak in the Power and yet he can Travel, meaning that in general he defies a trend that everyone uses.

So say what you want, but the high strength channelers can make big gateways, the average ones smaller gateways, and the weak ones no gateways.

It seems like splitting flows doesn't split strength, which is really strange if you think about it. One should be careful though - Egwene is never a good example of anything. She's one of those extremely rare channelers who is strong in all the five flows and also has multiple gifts and Talents.

Well indeed, and it seems like Rand could probably hold 14 weak Aes Sedai, but maybe not seven stronger ones.

I would agree with this because kids who are taught to be skilled often retain that skill into childhood, but adults often struggle to pick up new skills. I know people who have taught their kids three languages as infants and this would be very difficult for someone of our age. It's almost like you have to fix this into your developing channeling brain while you have the chance.

Rand was also completely untrained, and not only that but his weaves were highly skilled. He melted metal and knitted it into chain mail, and did all sorts of other things. It was a clear demonstration of multiple strengths and gifts that he wasn't aware of. He didn't even know how to shield a woman at that stage and yet he did.

Flow splitting is likely a combination of several abilities and strengths, though the precise formula is unclear. Why can Aviendha not equal Elayne? I think perhaps one could practice but I have strong doubts that everyone could be as adept as Egwene or Rand.

With what you and Darius have half proved is that perhaps her full strength is present in all her flows. Flow splitting seems to not split strength.

This is likely similar to Rand's statement than an Air bridge has limits. I doubt using a sa'angreal would improve on this.

As long as you aren't too much weaker than them.

Yes you probably have to establish this early on as a channeler. Once you believe that it's difficult the neural pathways set in and it really does become difficult.

This is likely true, but considering the risky nature of shielding, I think channelers try to increase the odds of success. Rand says that shielding a woman doesn't take 'mere trifles' of the Power, so clearly you have to make a weave of reasonable strength. I'm also a strong believe in precision weaving and that if you get a shield to have nice sharp edges you can not only shield someone, but sever them at the same time, as we saw with Moghedien/Nynaeve.

Remember also that Logain split his flows into a gateway and a shield, and Demandred considered the shield to be the bigger threat and went for it. We know that this shield was at best as strong as Demandred was but even the Forsaken knows that if this weave gets through by chance he's toast.
