I suspect that monthly probability of a revolt doesn't equal to displayed revoltrisk... How to calculate true RR?
Revolt risk (RR) depends on whether the province in controlled by a player or the AI. RR for a player is a percent chance per year (so divide by 12). RR for the AI is a percent chance per month.

If a rebelion happens in occupied province, does the rebels represent land technology of the occupied country or of the invader? Which technology level determines their morale?
If the rebels fight a player, the rebels have the exact same tech level and morale potential as the player's army. If the rebels fight the AI, I believe the old rules apply. Rebels have their own tech speed and investment. Rebels gain technology more slowly than the AI. The AI has a better chance of beating rebels than a player does. If there is a rebellion in one of your provinces, an ally or enemy army can wipe them out easily for you.
There is a trick where you attack rebels with a tiny force at the end of the month at 50% maintenance. Then you follow that attack with a large force arriving on the first of the next month at 100% maintenance. That is the only way to get the morale advantage over the rebels once the rebels have reached their full morale potential.
