If a large correction
begins with a flat a-b-c construction for wave A, expect a
zigzag a-b-c formation for wave B (see Figure 2-2), and vice
versa (see Figure 2-3). With a moment's thought, it is obvious
that this occurrence is sensible, since the first illustration
reflects an upward bias in both subwaves while the second
reflects a downward bias.

Quite often, if a large
correction begins with a simple a-b-c zigzag for wave A, wave B
will stretch out into a more intricately subdivided a-b-c zigzag
to achieve a type of alternation, as in Figure 2-4. Sometimes
wave C will be yet more complex, as in Figure 2-5. The reverse
order of complexity is somewhat less common.
