For additonal reference, refer to DOF in the Technique archives (about 1/2 way down) where Ron Shaw wrote:
An article in Photo Techniques (Mar/Apr 96) on view camera focus used this method. Basically, you tape or glue a mm scale on your bed, and then focus on the nearest object of interest, read the position on the mm scale, then focus on the farthest object of interest, and note its position on the mm scale, and then, using this focus spread (in mm), refer to a chart for optimum f stop to use, based on line pairs per mm resolution. I photocopied the chart and taped it to the back of my camera for reference. I hope this helps.

...and Alan Gibson did some fancy typewriter diagramming as a follow up.
I have copies of the articles referenced by Ron and they are useful, practical, flexible and well-founded. I don't have to take my calculator out nearly as often now. --Henry
