shooting ratio doesn't necessarily correspond to scenes cut, simply takes and set-ups. For example, Steven Speilberg has a low shooting ratio--he might film a scene from seven angles and do four takes each, and use six of those angles in the final cut. Francis Ford Coppola is usually known for his high shooting ratio--he might film a scene from ten angles and do eight takes each, and use only four angles in the final cut. This also extends to deleted scene material--speilberg might only have twenty minutes of deleted material in a film, while Coppola might have forty.
