Thank you lal.
The “ultimate two supersets” I commented on may not be what you had in mind. I was also thinking about whether that approach could be “too deep” for beginners. Please proceed the way you planned.
True. Not really useful to share the document with absolute beginners.
I really created the document for use of ariyas for their quick reference to various concepts, firstly for their own contemplation, secondly at the time of teaching someone, they can teach 4NT using document in various ways.
