As the author of an early software app which calculated a number of obscure astro. variables for observers, Dr. Pete's observation are close for an observer on earth--approx. 1 degree every 72 years. As you probably know, western astrologers stopped including precession in their horoscopes long before the first millenium CE, thus they depart from real accuracy in a number of ways since that era. Interestingly when I purchased a slew of texts from the library of a Sanskrit scholar who passed away in the 80's, among the works I got was the Surya Siddhanta, an old Hindu astronomical text. Apparently the Indian astronomers had a very old understanding of precession as this text included the formulae for these calcs.

As you may have seen in my original post  back to  peter (to which you responded) if procession does not imply  the sun rising from different directions, for example from the west  13,000 yrsr agos (half a precessional cycle), then why and how does  it make SV invalid in the long run -- as Peter has argued. I don't think your mental model is quite right, Not the first time its been off. :) Gee thanks. :) But its certainly true. but I'm not sure exactly how it's off, so I don't know how to help you correct it.  Do you therefore feel Peter's model is correct? If so, can you explain why? Precession is clearly real. The issue is does it effect the sun's directional relationship to buildings over long spans of time. It does not appear to. So why does precession invalidate SV as Peter argued? It changes by a few degrees over time. The 1 degree per 72 years  sounds off. Perhaps 1 second of arc per 72 years?
