The reason (as stated by Robert Schmidt circa 1994)
that 30 and 150 are not properly called aspects
is because you have a blind spot in your left eye that prevents Aquarius from being seen and a blind spot in your right eye that prevents Capricorn from being seen.
That's because the Moon represents the left eye (Cancer)
and the Sun the right (Leo).
(forget about sex differences here because this is a demonstration of a schematic).
The 30 degree relationships are also not visual rays
because adjacent signs are hard to see because they're sitting right next to you.
All aspects are a form of looking phenomenon.
Note that "aspect" and "spectacle" have the same root.
The other cancellation of aversions stated earlier are part of the other 4 senses of the cosmic soul
(part of Schmidt's early material first released around 1998) on testimony within the context of the "cosmic courtroom".
Note that if you cast rays out of each eye, that there are 7 rays (one for each planet) to the even and odd signs.
This is part of the Greek optical theory that Schmidt talked about around 1994 at the Back to the Future conference in Princeton, NJ.
Aspects are currently thought of as a combination of a pair of planet interactions but this is not quite correct.
That is because when a planet casts a ray toward another planet, that planet doesn't see the same thing that the other one does.
For instance when Venus looks at Saturn, she see's a dirty old man, but when Saturn looks at Venus, a beautiful young woman.
That makes a huge difference in delineation
because when the courtroom asks about marriage and the guest-host relationship is invoked,
the lord of the 7th has the job of asking the other planets for witness testimony.
Do you think that Venus is going to say the same thing as Saturn?
No.
You need to break down the testimony or you'll get vague generalizations.
