How much zeal is enough for the AI to consider converting their lands with the Nature "Unyielding"?

In the wiki it is written that when you use the Nature Unyielding the AI only converts their lands if it is zealous. Not the trait Zealous, but zealous in the sense that the AI has aquired enough zeal.

Asking because I can't take Bloodthirsty Gods and Proselytize together, but saw that some traits of Bloodthirsty Gods add AI zeal.

I always assumed it meant that AI characters would only set the chaplain to try to convert a county if they had the "zealous" trait.

But now I'm not so sure.
