Bill, as you know, I'm a stickler for test design. Given the difficulties involved, in addition to repeat testing (obvious) it is often helpful to do things a few different ways, which is what I always do. It takes time, of course. I remind everyone the point of this exercise was to compare shapes and the major characteristics of the curves. It is obvious repeatability to within 1 density point is not possible, nor is it necessary. Unfortunately the context of Mark's original post has been lost. In addition, nobody said fine prints cannot be made from this type of curve, nor is anybody knocking TMY-2, a wonderful film. As for the "curves shmurves" business, there is nothing about the posted curve shape that would indicate the film cannot hold 12 stops of good separations, although it should be pointed out a variety of films can do that.
