I am going to share something once again that not ONE person here has actually taken a very close in depth look at.

You'd be wrong about that (although I agree with you overall). I've been posting for some years, here, for discussion, those graphs going back many hundreds of thousands of years, or even millions of years. Here's a link to one:

Note the change in cycle periods starting about 1 million years ago, and note the increasingly wild oscillations in general.
