Give it up, Bagpuss. The premises (ie assumptions about astrology) that underlie your so-called "experiment" are fallacious to begin with. Therefore, the whole exercise is a waste of time. You wanna break your brain cells over it? Be my guest. And if you still cannot comprehend what I'm saying, try the following:

1. Study my hundreds of posts here, over and over and over again. WIth enough effort, someday soon a bit of the information might sink in.   

2. Pay very close attention to the links, quotes, and articles from the masters of science, philosophy, spirituality and psychology that I've provided. I mean it -- I'll quiz you on it later!

3. Go back to the Astrodienst site and click on FAQ. They do offer a good introduction to astrology in language even a newbie will understand.

4. Forget it.
