When your name is on a book then what's in the book is what you believe. Otherwise whose book and teachings are they? Just because Kempf says something does not mean its right.I would not criticize Kempf for one section in her book. When books are written, authors always get materials from others, as she did with the routine. (Many authors have used Kempf's stuff, ironically.)
The group is Club K. I don't recommend or use the routine, because who has time? You have to take completely off from pitching for your team for 8 weeks.
