The progenitor's ranking seems to be dependent on their agehood, so I thought not only think Saito is stronger than Krul, but because he also lived longer than her. The higher you're in rank as a progenitor, the older you're and how much power you will possessed than the rest below your rank. However, vampires of the same rank like Krul and Lest as third progenitors are uncertain.
