Stephen, I like the long luminance range (single set) example actually. I think this type of illustration is powerful.
I disagree with PE - I don't find these tone reproduction discussions over the top technical. In fact they are quite straight forward.
One thing I'd throw into the mix as far as over/extra and latitude goes is a consideration of image structure characteristics such as granularity, resolution etc. which may or may not contribute to the total subjective sense of print quality in addition to "macro" tone reproduction. As we know these characteristics are influenced to some extent by exposure.
