Cultural Takeover takes too long?

I've had cities flip at 40something percent, and I've had a city go five turns at 0% without flipping. I have no idea what the algorithm is.

Similar experience here. Maybe someone can find a piece of Python code that's determining whether a city flips or not, and can gleen something from it?
