What is NEoWave "Reverse Alternation" in a Triangle?

Most students of wave theory understand the concept of alternation as it applies to impulsive patterns, but are unaware that the same phenomenon that impacts development of waves 2 and 4 also impacts waves b and d (under NEoWave Theory) within all Triangle formations.
If a Contracting Triangle is unfolding, but wave-b is just around 38.2% of wave-a (instead of 61.8% or more), then wave-d (to create proper alternation) must be larger than wave-c. This creates a Contracting Triangle that follows all the important rules (i.e., wave-c is 61.8% of wave-a and wave-e is from 38.2% to 99% of wave-c, plus wave-a is the most violent in the pattern), but the Triangle does not channel as you would expect during contraction. Instead of the trendlines converging to a point, they will tend to be parallel.
If reverse alternation occurs in an Expanding Triangle, wave-b is likely to be around 138% (or larger) of wave-a, which then allows wave-d to be much smaller than wave-c. Wave-c must still be larger than wave-a and wave-e must be larger than wave-c, but the behavior typically seen between waves-b and d switches places, creating NEoWave Reverse Alternation.
