am trying to get the only decent HRE ancillary but having some difficulty-

Trigger hildegard_von_bingen_anc_trigger
WhenToTest GovernorBuildingCompleted
Condition FactionType hre
and SettlementBuildingFinished >= church
and I_TurnNumber >= 20
and I_TurnNumber <= 50.

Do i interpret this right after turn 20 any settlement with a church which a general constructs something entitles you to the charactor.

Does being excommed effect the chances.
Can more then one general aquire the same ancillary or is it one only available
