I think one of the advantages of AD's plan would be called the "Hammer Effect." With the continuous vacillation of the monthly peaks and troughs of the Estrogen & Progesterone levels, it acts like a hammer on the hormone affected systems. When drilling through concrete, a hammer drill is much more effective than a standard drill. Likewise, it appears that the human body works in much the same way.

Just my never so humble observation and deduction.
