I had a flash of insight about why it is I can never, never catch up enough to be the ideal "two to three months before due date": it's because even if I were to catch up right now and be working on January due dates, questions would continue to come in for October, November, and December. Since I go in due date order, I would tackle the new questions--and by the time I was once again caught up to January, it would be back to "two to three WEEKS before due date."
So possibly what I need to do is CLOSE months: I've finished October due dates, so perhaps now I could say "no more October due dates." Then when I finish the November questions, "no more November due dates." The problem with this---and it's a big problem---is that many questioners NEED help at the last minute.
Well. Still without a solution, aren't we? I'll continue to mull. I found your suggestions on this post very good mulling fodder.
