You stated in the sub-thread above that Androl's gateway talent disproves Logain's gateway comparison as strength evidence.

Well, it does not. Look at the context.

Yes, there exists some form of gateway talent, just like Berowin's shielding talent. But channelers' own comments prove to us that this is rare enough that gateway size in general is very strongly associated with channeler strength.

And in particular, Logain's comment tells us that in the Logain/Rand case, it is stronly correlated.

Logain is a leader of the Ashaman who has direct experience of the strengths and gateway sizes of hundreds of male channelers.

And clearly, based on his experience with such a large number of channelers, strength and gateway size is correlated in such a vast majority of cases that Logain feels Rand's gateway size is a very strong indication of his comparative strength.

And furthermore, Logain only makes this comment AFTER sensing Rand's full strength, and commenting on the fact that this indeed is Rand's full strength.

Hence, AFTER sensing Rand's full strength, he still states that their comparative gateway sizes are in correspondence with their strength difference.

Logain himself makes this evaluation, having both their comparative gatway sizes and comparative strengths at hand to make this comparison. And he STILL is comfortable that the one is in correspondence to the other.

So definitely in this instance strength is related to gateway strength, and quite accurately too, and judging by Logain's confidence in the obviousness of the correlation, also in the vast majority of other instances, gateway size is perfectly correlated to strength.
