I have found 2 different patterns, alternating between years. For instance, 2013 had a A-B wave, or 1-2 wave - pattern #1. Where 2017, and the one prior to that, was an isolated, lengthier event - pattern #2. Those crashes of pattern #2, see falls of around 80%. But for pattern #1, 2013 double wave, we only see a fall of 50% in wave 1, then a huge movement to top of wave 2, where we then finally see the 80% drop again. I also think we will diverge from the traditional 4 year pattern this time, we should see the length has been doubling.
