I believe the idea is thru a test, set a ISO rating for your choice of film and developer to give a normal development for zone 5, which you carry across into your paper exposure and development. This sets a logical sequence that gives you a standard from start to finish. From there you set your N- and N+ film development, which is easier shooting cut film and from the beggining. What I did was to shoot a roll of a scene with no brightness change with under, average and overexposure up to three stops either way and develop the film in Diafine. I compared the negatives (either thru printing or scanning) and found out how much I could deviate and still get a good negative. But if your not interested in using a compensating developer, just shoot multiple exposures based on your tested film/developer. Film might not be as cheap as it use to be, depending on the film of course, but it's easier to carry one body then three, and perhaps a tripod as well. As concerns 3 backs for a MF body, it's the same amount of shoulder/backpack fun cause your lenses and accessories are going to up the pack weight. When I was younger I carried a big pack which became smaller and smaller till now it's a body with 2 lenses and a light tripod normally. Of course it just depends on what you need to accomplish.
