The difficulties that may occur at this level include problems in the recovery of the invariant motor plan, in identifying the motor goals of the phonemes, in the sequential organization
of movements for each phoneme and for the movements for series of phonemes, in the synchronization between articulators, etc.
This means, that the m-staged pipelined synchronous organization is m times more productive than a sequential organization
with synchronous execution.
The abstract language of the notations was unintelligible to Berger, but he noted that their left-to-right articulation and sequential organization
in horizontal "statements" paralleled the way text works into pattern.
To name just a few: odd formations, shifting, motion, the option, misdirection, sequential organization
of plays, and blocking schemes that double bind, double team, and double-cross the defenders.
They attack the book's linear sequential organization
, arguing that it makes either the deliberate or random access to selected portions of the text cumbersome.
