Peter,
I was at work yesterday, and didn't have a chance to fully respond. There is no cycle inversion, once again. It is natural for the cycle one is watching to be pulled this way and that by a larger cycle, or confluence of large cycles, or larger cycles, plus smaller cycles. If one takes the course, you draw a grid connecting dots for all cycles in a time period. It's very illustrative of this process. Time for me to hit the books again, I've really forgotten most of my Hurst.
As you said, if we top right here, and start to go down, means 20 week is right on schedule.
Life is good, hope same for you.
