John, as I have been saying all along, we are talking about different subjects. And I feel that your note shows that this is still the case.

The system which I am presently studying is dominated by the rotation of the Earth and the moon around their shared center of mass, not by the Earth rotation around the sun or by the Earth rotation on its North – South Pole axis.

The central reference point for this system is the time of the month when the sun – moon - Earth are in a straight line with one another, in that location order. A secondary reference point is when they are in a sun - Earth – moon location order.

I feel that in part because you are still not talking about the same topic that I am discussing, your comments regarding triggering effects do not apply to this discussion.
