Actually, I slightly changed my opinion on this matter - http://skyscript.co.uk/forums/viewtopic.php?p=105986#105986. They were actually proper siderealists, not pseudo-tropicalists.
Keeping the VP stationed at that degree and using a formula instead of just changing it, does favor the theory that many thought it was a trepidation and that it will return to it at some point. One of the ''ancients'' mentioned by Theon might have been Valens and Manilius as a result. There is no other way to explain this 8 VP confusion without this view. Everything falls into its place, once you think from the viewpoint of Theon's ''old astrologers'' and trepidation theorists.
Having a formula with an equinox is proper sidereal astrology, even if you do not realize precession is a one way trip. Every ayanamsa in India is calculated in this way, using an offset from a tropical zodiac, in fact some of their ancient astronomical books surprisingly? also contain trepidation theories.
