There have been several attempts over the years to identify trends in solar and
geomagnetic indices that predict propagation on 160m. I don't beleive any of
them met with much success (as you also concluded).
What that says is there are other variables running around that we simply don't
understand. First, I persoanlly believe the biggest hole in our knowledge is
events in the lower atmosphere that couple up to the lower ionosphere. Second,
I don't think we fully understand all that happens with elevated K indices.
Unfortunately, I don't think we'll figure this out in our lifetime.
So listen, listen, listen.
