CK2's depiction of seniority is wrong, as sorts the succession by age, in reality, the seniority system functioned like a ladder, where the ruler was succeeded by his brother, and when the last brother died, he was succeeded by the oldest brothers oldest son, and after all oldest brother's sons were deceased, the property moved to their oldest uncle's children and so on.
Rota system, on the other hand, is an interesting variation of agnatic seniority, where they would exclude the descendants of princes who died before they ascended, making the pool of heirs significantly smaller and easier to track.
Correcting seniority and adding rota system variation of it would be a nice addition
