Jeffro --
I haven't gone back to read carefully through all of the messages from the last few days yet. I have a nasty cold and my brain has turned to cotton. 607, 586, 70 this, 70 that ... blahhh.
But I have to tell you that my antenna are quivering over the way you've taken hold of my comparing it to a "collective noun." I am not at all sure I feel comfortable with that. I only meant to explain (away) the singular form of the demonstrative and I fear that I have unwittingly emphasized the noun. Narkissos's explanations are far superior to mine. I hope he'll jump in.
As I said a couple of days ago, you should try reading two times through the list of verses I posted. Read them with "these" and then read them with "now."
Since I haven't gone through all of your messages line by line yet, I may not have grasped exactly what you're saying. I want to be sure before I comment.
Incidentally, I did want to point out that there are literally hundreds and hundreds of verses with the demonstratives. If you add up all of the masc. and fem. singular and the common plural occurrences, there is a vast number. I wasn't sure if you understood that? I was culling the ones which had to do with time, but I left out all of the general time expressions and focused on the ones with exact numerical units.
