This part completes the discussion of dating deep-sea cores by examining the new method of paleomagnetic stratigraphy. Too many unsolved problems exist to objectively date ocean sediments by magnetic reversals. Other possible mechanisms that may cause reversals in rocks or sediments are discussed. The dated oxygen isotope fluctuations are statistically analyzed for the controlling frequencies by power spectrum analysis. The predominant cycle matches the exceedingly weak eccentricity cycle in the Malankovitch theory. Even though this is claimed to prove the theory, it has caused even more serious problems. The question naturally arises of how order can be generated from the chaos of uncertainties and problems to produce their consistent results. It is shown that extreme bias in the astronomical theory has caused the manipulation of data by various means, and the "reinforcement syndrome" acts like a traffic policeman to keep data and researchers in order.
