I don't feel any need to address your assumptions and guesses.
There is no guess about what the DI is. That's been established fact since the Wedge Document became public in 1998 and was reinforced during the Kitzmiller case. There is no room for argument of that fact among rational individuals.
As for my guesses about the article:
1) Evaluates textbooks based on a highly limited selection of cherry-picked items (usually things that have been addressed many times already such as the inclusion of Haeckel's drawings, the "Cambrian explosion", and the peppered moth photographs).
2) Has absurd requirements which result in artificially low ratings even when a particular item is handled in such a way as to admit the inconclusiveness of an early experiment or that an early theory has since been discredited.
3) Uses out-of-context quotes and deliberate omissions in many cases to intentionally misrepresent the actual reading of the section of the textbook in question.
4) Assumes without evidence that its own position is flawless and fully conclusive, generally citing biased works by persons with limited (if any) scientific background.
1) Check. Spot on the money. It focuses on very early experiments that have been addressed and readdressed many times over.
2) Check. A rating of "C-" is given despite the information including a full caveat about the experiment having been discredited by later evaluation simply because the caveat is given after talking about the experiment rather than before.
3) Check. The provided quotes from the textbooks are uniformly short, often not even comprising full sentences, let alone proper quotations of entire paragraphs which would permit an honest evaluation of the tone of the textbook.
4) Check. Includes citations of such scientific paragons as "Time" magazine, and the quotations selected from reputable sources are chopped and intentionally misrepresented. Evidence counter to their claims is ignored.
Looks to me more like you chose not to address my "guesses" because they turned out to be uncomfortably accurate.
