The Merean reference is an overreaction on your part. You seem to think that I was trying to make a point about the weight of the people Merean was holding in her weave of Air. In fact, I was doing no such thing. It was not really important whether she was holding three men, or a man, woman and child.

The point of that post was that Merean was holding 3 other weaves, and was still defeating Moiraine. Moiraine herself stated that she was losing the battle and was hoping that Lan could intervene to help her.

We know that holding two weaves is more than twice as hard as holding one, and that holding three weaves is more than twice again as hard as holding two, and holding four weaves is again more than twice as hard as holding three.

So here we have Merean, wielding three substantial weaves (holding people in weaves of Air), and at the same time wielding a fourth weave which is gradually overcoming Moiraine in a one on one battle.

So the whole issue that you're raising is in fact a non-issue. Moiraine's herself raised the fact that Merean was so much stronger than her that she can handle those three weaves and at the same time be more than a match for Moiraine. This was borne out by the ensuing battle.
