I came late to this and dont really understand, (sorry) but are you saying the earth spins perfectly on its axis and there is no wobble or deviation even after 24,000 years?
SI, walter Cruttenden, a wealthy SRF member, has been hiring consultants (astronomers) to work on alternative hypotheses on the cause of the equinoctial precession (among which: the sunA-sunB binary star system). Cruttenden was inspired by SY's 'The Holy Science'.
Some hypotheses, based on scientific facts and observations, are outlined in his site:
