Multiple Arrests

I am pretty impressed with this fellow who has been arrested 1,000 times. They don't quite cover it in the video, but the question then really is, what percentage of the time are you in jail versus out of jail. I mean, this guy must know the system inside and out.
For example, I assume he is up on this evidently common prison trick of getting seroquel for kicks. It seems like a stretch but I have no idea what seroquel does so maybe it's the best drug ever invented or something. Who knows.
