I have just read the post from MSF:
a friend of mine on a recent w&b course in DUB told me that his instructor didn't know what she was talking about and all her students bar him failed the final exam.

Instructors can teach anything methodology . An approach that demands the Documentation is written by those who do know the subject inside out and have taught it, so know the range of questions and queries those on the course will ask. Then the nominated instructor will still require preparation time to learn the course documentation and time to be fully prepared for each lesson.
Although I find the process counter intuitive, it does work, providing:
A Good Instructor, Top Class Documentation and sufficient preparation time. If any of these requirements NOT met, then those on the course are wasting their time and someone's money.
It appears that MSF friend had a course where none of the above requirements appear to have been met.
