I was trying to discover the rate of conversion when you stick a bishop in a heathen country. With 7 bishops, one of whom was 3 star and the rest 0 star, the jump was 14% in one year (from 32% to 46%), the initial year. In a subsequent year, there was only about a 7% change.

Anyone else know what the numbers are? Does the number of stars affect ANYTHING or is that simply a reflection of difficulty to assasinate? I don't know how to raise the valor of a bishop, nor do I see application if you did manage to do that.

Now, those numbers on top might be wrong or skewed, but I didn't have time to do more experimentation with it. When I put 4 bishops in Livornia, the AI sent 3 more foreign bishops in, as well. This clustering of bishops also occurred in Antioch, when I sent in 4 bishops; 4 more bishops from factions which were NOT adjoining the land (nor did they seem to have any interest) appeared the next turn. Sure, they all work for the same church, but allied to governments with very different agendas, so I was puzzled about that one.
