Not until I had a session with Yoda and Yodasluke did I understand 10-14-B. (In the unpublished 7th edition 10-14-B is standard action for hitter AND swinger) - i.e. 12-1-0-14 and 12-2-0-14 are changed to "B Slide".
More in detail, 10-14-B is SLIDE-TURN-SLIDE-TURN.
Which for a righty SWINGER means:
1. Slide hips parallell along target line AWAY from target (Do not exaggerate this move!)
2. Turn hips right
3. Slide hips forward
maintaining the turn (clear the hips for the downswing)
4. Turn hips left
YodasLuke mentioned that the best ballstriket he ever knew said he had a feeling the tailbone was pointing left of target during forward slide.
To me the big aha was to keep the hips turned during the forward slide - at least initially. Also puts less strain on the back.
A drill might be to put a finger on yours nose and hula-away, but I am sure someone else has better ideas.
Not a trained eye, but I'd say these moves by Miller are 10-14-B.
