Sometime stuff just escapes my attention. Such was the case with the 804 - 840 connection. My programs don't find that pairing because it has never happened the exact same number of days apart, but 840 has been reliably following 804 for a decade+ and I just hadn't noticed it before. Here is the history:

That one should have been the clue, but I missed it, again, because it has not duplicated at exactly the same number of days.

Someone could say, well, hasn't 804 ever followed 840? The answer is, No, not within a month. There's no hard and fast rule to it, that's just the secret life of the 804-840 pair...
