Thanks, Happy Easter to you as well!

I don't have a tremendously large amount of bandwidth at present for these matters, but if at some point that changes I will spend a bit of time carefully looking into these matters and attempting to understand how to extract some useful and terse mathematics out of it. Parsimony seems like a good policy, but [as a well known writer adroitly pointed out a bit more than a century ago](https://www.goodreads.com/quotes/21422-i-didn-t-have-time-to-write-a-short-letter-so), it is often easier to write a long commentary than a short one. I'd rather aim for quality and brevity here, if possible; and that sort of thing requires effort and time.
