I watched A&E's biography of the Gambino Family on Sunday night and one of the things that stuck out to me was when they mentioned that at its height under Carlo Gambino they had about two dozen crews. I take it that a crew is the same thing as a regime. If that's the case is it unrealistic that the Corleone Family, which was as fictionally powerful, if not more so, than the Gambino Family was in real life, had only two or three regimes?
