ANSWER:

Under NEoWave, in any Flat or Zigzag, the size of wave-b provides crucial information regarding the size of the future trend. 

In Flats, the larger wave-b, the larger the post-Flat trend; the smaller wave-b, the smaller the post-Flat trend. If wave-b of a Flat is larger than wave-a, the post-Flat trend will be at least equal to the pre-Flat trend and frequently 161.8% or more. 

In Zigzags, the closer wave-b is to 61.8% of wave-a, the greater the chances wave-c will be smaller than wave-a. The smaller wave-b is in a Zigzag, the greater the chances wave-c will be 161.8% of wave-a.
