black, 2 points:
1. I am NOT a beliver in "strict" nesting of the lows, i.e. I subscribe to Hurst's book proposition that the cyclical lows do arrive together, but that they can be spaced out a bit.
2. I wrote awhile back on a couple of occasion that there is a "problem" with 4-4.5 year cycle vs. 80w cycle - since there are three (3) 80w cycles within one 4-4.5 year cycle (the only cycles NOT related by a factor of 2), the RT 4-4.5 year cycle would of course top about 66% into its cycle length - since 4-4.5 year cycle is 48-54 months, that would normally be about 33-38 months from the low - but 36 months is where the second 80w cycle would bottom (80w = 18 months) within the 4-4.5 year cycle - so I speculated that perhaps we will see a "cyclical inversion" (even though there is NO such thing) where the topping of the 4-4.5 year cycle negates the upcoming 80w cycle low i.e. the result would be only a minor retrace, and NOT a large sell-off into the 80w cycle low as one would normally expect.
