The more printing skill and tools one develops, the less mechanical/formulaic one has to be when making exposure and development decisions with the ZS (or with any system). The negative becomes more about recording the information needed to support the visualization, and less about simply increasing or decreasing CI to fit the paper. Particularly when dealing with high contrast scenes, a "naive" approach to the ZS (eg: highlights on Zone XII = N-4) can sometimes lead to more loss than gain. Printing is power!! Or something like that anyway.
