which somewhat contradicts your section # 4

From tFoH, chapter 54:

Four paces was as large as Rand could make it. There were limits for one man by himself, Asmodean claimed; it seemed there were always limits. The amount of saidin you drew did not matter. The One Power had little to do with gateways, really; only the making. Beyond, was something else. A dream of a dream, Asmodean called it. (emphasis mine)


I'm not saying this necessarily disputes your claim, it's just the original quote we have from the books concerning the making of gateways. The only thing that really doesn't seem to make sense is that Aviendha has to use so much of her strength to open a gateway, while Rand's pov states that the amount of Power you draw doesn't matter.

One theory explaining her difficulty is that she is having to relearn a weave she used before she knew what she was doing. (I find that hard to believe since she only used it that one time, and she did it without thinking out of pure panic.)

Others think that she gets embarrassed thinking about what happened the first time she Travelled, and that is the source of her problem. (That may have held true the first few times she used it again, but I'd think she would outgrow that fairly quickly.)

And still others put forth the theory that she time-travels when she makes her gateways. (One of my older ones, btw)

Other than her, I think most of the quotes in the books would support your idea. Even when the women link to form a gateway, they are probably just increasing the potential Power, and not using the full strength of the link to make it.
