616 days: As shown on this chart, the wave C decline is (approximately) 1.618 times (Wave C = 161.8% of wave B) the length of wave B (Wave B = 123.6% of wave A). What might this be? Expanded Flat ?
Nothing is going to work all the time (630 days)! : This wave count argues that the Cycle wave correction from (Dec) 2013 ended in (Aug) 2015. What happened next?
