I'm actually commenting on you, Sharper...
But you mentioned my ignorance towards astro so here's a few thoughts:
First, the earth moves in 365 day. Now that's very close to 360. As you know Gann relates one year with 360 degrees. In another words, Earth has a natural cycle of 365 days(360). Now, if there is one cycle existing there are other natural proportions like 1/2, 1/3... and etc. etc. based on musical acoustics. Along with that you'll see resemblance with other Master Charts like Square of 9, 12, 360, Squaring the Circle Charts, Hexagon, Even/Odds and etc. I've been able to relate these scientifically and have a fair view of how they are applied.
My next step is astrology. As I said above, there are natural proportions, planetary motion closely resembles with the molecular structure's motion of electrons. I already know Kepler's Law and I've read some books on Astronomy and Astrology.
Because Planets move in definite law of motion and because Earth is part of the solar system. Disregarding the gravitational and electro-magnetic influences, there has to be some cyclical influences just based on Earth's cycle. Just like how upper partials of Earth, 4 seasons and etc are evident.
Now, the last part is still an assumption but that's my basis of looking into Astrology. I've found few but I'm looking into it.
Now, I hope you know I'm not ignorant about Astro.
