"But the A.'.A.'. system is not a closed system, and has plenty of room for improvement, no? Perhaps I'm misunderstanding what you mean by "formal"?"
By "formal place in the system," I mean it is not assigned in any grade, taught in any grade, tested in any grade, nor part of the system per se in any way.
In terms of "plenty of room for improivement" : In the sense that everything is subject to improvement, yes, I'd have to admit that. However, in practice, for the long foreseeable future, it's "closed" in the sense that our duty and commitment are to deliver it exactly as its founders created it. This is my commitment to Soror Meral, and I see no reason to waver from it.
The system works as is. One needn't mess with success. Having the some tasks and means of testing for all people is pretty basic to its constitution. All of us in the system do, of course, also explore all sorts of things that are not in the system - that's what people naturally do. But that doesn't change the core system itself.
