And one more question about revolution components. I am out of city to check it for myself, but RI keeps all my thoughts even at countryside

How exactly separatism_revolution works? Let’s say I set that value as 8, and my state religion is hinduism. As far as I noticed, all cities not having hinduism present will have half of the penalty (4 points towards separatism). I guess if there is a non-state religion present - I will get the whole (8 points penalty), if there 2 non-state religions, do I get 16 points towards separatism and so on, right? I mean each non-state religion further increases the penalty by 8 points each? And what about situations where ONLY non-state religion is present compared to situations where BOTH state and non-state religion(s) are present? Does also having state religion present lowers the penalty? Also I guess, under civics with no state religion, I get no penalty because of this parameter?
Sorry for so many questions at once
