Not having looked at the flick book, what did they leave out? Or Wiseman's basic book? For a general outdoorsman, I don't see much missing.
Everyone has a pet technique if they are involved in this often enough, but that is generally a refinement of the basic principles of any technique or involve aspects of a fairly technical activity like climbing or caving or diving. I don't ding every writer who doesn't have a silcock key and a current detector in their urban book.
