The commonly cited figures for Psycho — the shower scene: around 78 camera setups and 52 cuts across roughly 3 minutes of screen time, storyboarded by Saul Bass and shot over about a week of the schedule — an enormous spend of resources for a film made on a TV-unit budget. Numbers vary slightly between accounts; treat as order-of-magnitude correct rather than exact (Rebello).
The analytical payoff isn't the trivia, it's the ratio: dozens of shots, and not one shows the knife penetrating the body. All the violence is manufactured between shots — Montage doing what a single explicit shot never could, and doing it so effectively the censors saw nudity that wasn't photographed (The Production Code and Psycho).
