Wave2 If wave-1 turns out to be (or is believed to be) the logest wave in the sequence, the second wave cannot retrace much than 38.2% of the first wave. If the first wave is not the longest wave the lowest point of wave 2 can retrace as much as 99% of wave-1. If wave-1 is a polywave or higher,the 2-wave must subdivide into a polywave or higher pattern. If the 2-wave subdivides and wave-a (in wave-2) retraces more then 61.8% of wave-1 the entire correction will inevitably turn out to be a Double Failure or a C-Failure, with the C-failure occurring at point 61.8% or less of wave-1
