As I understand it, and I stress I could be way off base, the Taylor book does not take CYA into account with their recommendations in the book. That would, at least to me, invalidate a lot of what is in that book. A question about that, though. How can a company that makes such an excellent kit not know about something a important as that?

If you want/need to know more, Chem Geek has several posts/threads detailing the relationship, I think.
