Maybe; all have large target markets and the last two have unique things.

That said, let's say you're 100% correct. I went back and forth on whether to even include the rubric, because I myself (the author) think it's a little silly to pretend there's a formula.

I found in early feedback of the article, however, that it forced people to really ask themselves good questions, which they might not have done if they read only the rest.

Therefore, I felt like it was useful for that reason -- posing good questions that folks should answer -- but I agree with you that it does have the problem of being a "formula" that cannot really be accurate.
