How many users behind a single public IP, before using PAT pool?

People who manage large enterprise networks, do you have a pre-defined number of users that you run behind a single public IP before you need to expand to a PAT pool?

I've seen situations before where it's been exhausted at peak utilization, and the obvious solution for this is to just expand to a PAT pool, but I'm curious about what experience others have had. Is there a spot that the line would normally be drawn, or do you normally just increase the PAT pool as required?
