The only thing I would point out about the article is that it basically is a tabulation of model results, an extension of the model presentation, what do you get if you run the model over and over kind of thing. The modeling of dirt is in itself an attempt to extend a limited paradigm of MF measurements (aka commercial broadcast band), focused on measurements at the ground for very practical reasons (Norton-Sommerfield) and has its own set of well-known issues. It is quite common to model radial kinds of issues and then install a design and find quite different results. Dirt, and all its variability, remains notoriously resistant to being modeled. Modeling can, I say "can", get one in the neighborhood and it's back to cut and measure, and a degree of common sense.
