Hi Robert,
Simply highlighting the ~1 page of arguably controversial stuff in a 67 page document is also unlikely to be optimal, because it creates a biased and misleading impression of the whole document, and gives the impression (accurately or not) that one's main interest is stirring up controversy.
That's very dismissive of legitimate concerns. If something is of genuine worry, how many pages should it take up before we are allowed to raise our concerns about it?
Where there's a genuine worry, I think it's much more likely to get a constructive response if the worry is expressed with understanding of the context.
"Here are my five concerns about this document" is quite a different thing to read from "Most of this document seems pretty sensible. However, are five concerns I have about it, though I think I have only spotted one of them actually happening at all"
Regards,
Chris
