There are no tropical and there are no sidereal TECHNIQUES. There are only astrology techniques. Good techniques work better with any zodiac choice or ayanamsa. I spent two years testing all my techniques and tropical tested out to a higher percentage with Every technique. That's why I started to use it. Its not a matter of believe, its a matter of testing. But those who want to use sidereal can use all my techniques with sidereal, just don't ask me to analyze a chart in sidereal.
@ernst Since you do not want to analyze a chart in sidereal, it can't be just techniques, can it.
What would be the difference if you analyze a chart in sidereal, and why would you not want to analyze a chart in sidereal?
I would not analyze a chart in sidereal as my results would be less than with tropical. Like I said, I tested all techniques on both zodiacs after using sidereal for 12 years and tropical tested out better on all techniques. So why would I want to reduce my accuracy by using sidereal?
