I just think it is extremely hard to keep all of this accurate given the wealth of data out there.

I think the most likely scenario is that this is somewhat vague in the notes, since we really do not see much 'typical' sa'angreal use in the books.

I would bet however that you could easily call it a Resevoir, vs a magnifier since essentially its the same thing for most people.

If the CK grants you 50,000 times your power... a "strong" sister which was I believe 15-25 in the old power scale.. gets 750,000 to 1,250,000??!? And Rand gets 5 Million?!!? I mean these amounts of power are so vast to be irrelevant.

Also I would not put much stock into the clensing comparison of a mountain to a molehill for Saidar and Saidin. Remember that the conduit Rand weaves of Saidar is JUST that... the funnel through which the taint cannot pass but he has to in essence funnel the entirety of Saidin through it. Of course there is a difference in the 'amount' of power used.

I believe more conclusive is the explanation for how angreals buffer the user from over use. As does Sa'angreal which was stated about Nynaeve at the cleansing. If it granted a well, how could there be a flaw in Callandor? It grants what it grants, you can't 'flaw' that and kill yourself. That imo is the evidence supporting its a higher multiplier, even though it could be viewed as a huge reserve of power given the numbers. I believe the power required to use these strong devices are because lifting 200 pounds is far harder than lifting 50 regardless of the relative ease of the stronger person, they still use far more energy or calories to do it in proportion.

So Egwene on forkroot is a 5? Strong pre WoT Aes Sedai are 30's and 40 for cadusane? well Vora's granting some insane multiplier like 1000 makes her a 5,000. Case closed in my opinion.
