Two questions on preaching

[General Tacticus]

As far as I know :

- Preaching has a chance of success equal to your God dominion * 10%. So if you gave your God Dominion 6 at the start, preaching has a 60% chance of success.
- Every five temples you build raises this chance by 10%
- If it succeeds, your dominion in this province goes up by 1
- Preaching can't raise the dominion of a province above the preacher holy (or unholy) score. A lvl 2 priest can only preach to level 2. You get a message ("XX cannot raise the dominion of the province any higher") if you try to preach but can't raise the dominion (but the order to preach stands).
- If you put a priest on "preach" order, and leave him there, and he hits his limit, you won't see any message, and he'll keep preaching without further effect.

And finally :
- preaching in an enemy province makes your priest more likely to be discovered, but can be done. Searching in an enemy province can't be done, but don't ask me why...
