@MLClark Yeah, we have to be our own editors. I've taken out more than a few adjectives and adverbs that could be construed as opinion.

OTOH, I think it's fair to argue that the publisher and the reader expect our opinion. I reserve that for the conclusion at the end of each chapter. By that point, I think I've laid out my evidence to justify my conclusion.

The good thing is that I'm near the book's end and so far haven't found anything to contradict my basic thesis.
