I like the idea, but IMO, the gray scale that is presented should be in keeping with a bonifide zone system gray scale, especially if references to zones are going to be your norm. I realize you are in the beginning phase of it, but for example, your Zone I contains way too much detail to be Zone I and the same for Zone IX. I would simply refer you to The Negative and the chapter on the Zone System and the sub-sections of "The Exposure Scale" and "Dynamic and Textural Ranges"------------it's all there and is easily understood. I've created the gray scale as described (after doing effective speed tests of course) and it pans out that way very well. Again, it's a good idea IMO.
