Is Deng's Complete Collection of Four Fathers in Seven Houses accurate?

Unless you look up the seven strategies and four excerpts of the earliest version of ancient books, it is really difficult to have a unified standard, because different people use different calculation methods from different angles, and because the universe is constantly expanding, the position of stars in today's system will definitely change greatly from that in ancient times. There are fewer and fewer stars in the sky, and a lot of astronomical knowledge that we modern people can learn can only be known by consulting older preserved ancient books. In addition, what is important is the nature and method of astrology. No matter what method is used, as long as the final calculation result is accurate, it cannot be said that the method used by astrologers is wrong.
