I can feel your pain. If you go back a page 118 you can see I experienced the same problem. I metered the bias while turning the pot and I think that got me started turning it the right direction.
Clockwise, Counter-clockwise...it is just all so confusing. The meter knows best. Two other bits of advice I received which may or may not help. Have the volume turned all the way down and let the amp warm up a little. I think I left mine on overnight w/ no inputs.
I just checked and Counter-clockwise is reducing the bias voltage on mine.
