This link is simply amazing. He gives the numbers I've been searching for. Finally!!!!!Now, here's the deal: http://forums.civfanatics.com/showpost.php?p=12621735&postcount=6
Cities gather religious pressure points, being atheism considered a religion. Population follows a religion with the same ratio as the religious pressure. If a city has gathered 1000 from judaism, 1000 from atheism and 2000 from shinto, then 25% will be judaist, 25% atheist and 50% shintoist.
A missionary spread religion action adds 1000 pressure points of its religion to the city. If the missionary is injured it may be less. The Prophet spread religion action removes previous pressure pool and adds 1000 pressure points of its religion. The inquisitor removes 'heretic' pressure points.
A newborn citizen in a city adds 100 atheist pressure points when the city isn't following any religion, and 100 religious pressure points when the city is following one.
Beliefs can increase the religious pressure strength or make it more resilient against religious actions.
EDIT. The guide should be right now.
Do you know if this has been changed for this mod?
Also I still don't know the changes in this mod for passive pressure. People have mentioned that distance is now a variable but won't say what that variable is.
