Hi Robert,
Well spotted with the avatar. I am interested in matters barycentric, thanks for the links. The relative distances of the planets from the sun and relationships with the solar cycle is given a different and interesting treatment by the (unfortunately banned) Ray Tomes in these threads:
Harmonics Theory
Explaining Planetary Alignments Relationship to the Sunspot Cycle
He finds the outer planets on the nodes of a 160 minute lightspeed wave and the inner planets near a 5 minute wave.

Landscheidt has interesting things to say about jupiters motion, barycentric motion of the sun, and earth's geomagnetic index here:

he links this motion to El Nino here: (among many other of his papers)

All of which is as you say, tangential to your thread, although as a non-statistician it would seem that Landscheidt is reasonably rigorous in performing tests for confidence levels and null hypotheses.
