As far as the outer planets are concerned then you are dead right. It's difficult for people to look back at their notes of "what happened last time" if there wasn't a previous time observed.
The solar system has an obvious religious element as is demonstrated by the planets being named after gods. A lot of scholars went beyond simple observation and correlation, and extrapolated that since Mars the planet is red it therefore belongs to Mars the god of war, so tended to emphasise martial qualities in their writings.
The job of modern astrologers is to try and make sense of thousands of years of sometimes contradictory history. When I was a kid at school our chemistry teacher taught us that atoms are composed of protons neutrons and electrons. Then he said this is not strictly true but it is a good way to visualise what happens to them. Astrology is the same - it doesn't matter if it is "true", just if it is practically useful.
