For Governorships, age, Family Rating, Level of Influence, and Estate Buildings are the main factors that determine this limit.
For Clerical Appointment, age and Level of Devotion are the main factors that determine this limit.
Children have a small scaling malus to this limit, while adult's limits rise as they age.
