My impession was that the AI was likely to assault the castle if it had a large army and the garrision was small. In one case, I think the AI assaulted on the turn before the castle was going to surrender possibly because the garrison was weakened by the abstracted losses it suffers each turn. The AI may be multiplying the strength of the garrision by a factor that depends upon the size of the castle in making its decision to assault.
