In fact the ultimate in chimping happened in the movie business.
For years now when shooting a movie in film, the director and DPs would shoot a video assist that they could play back to see if they liked the shot, the blocking, the acting, the lighting etc. It saved them a ton of money on extra takes and hours of time.
They simply mounted a digital video camera with the main camera and captured the identical shot on both cameras.
Then they'd have a "group chimp".
