Hi hhEb09'1, I am surprised that anyone remembers me here. Thanks. Yes, the GPS stuff was what let me discover the forum.

You are right that the 4:5:6:8 frequency ratios are the major chord, and that was what I originally found. The periods 4.45, 5.9, 7.15 and ~9 years were all 35.6 years divided by 4, 5, 6, and 8 (in the opposite order). As regards the two ways of harmonics arising, I think that the major scale arises most naturally as multiples of a frequency and the minor scale as fractions of a frequency. The Harmonics theory relies entirely on multiples of frequency, though I have looked at the other way and been asked about it before. I cannot see evidence of either a method of it happening in non-linear systems, nor evidence of its results, so feel happy with the multiples.

The harmonics theory naturally works from the top down in the universe, easily explaining the large scale structures. The big bang theory supposedly works from the bottom up, but does not really explain any of the structures and struggled with the mere existence of large structures and so needed additional axioms to get close to working.

Originally I started following the economic cycles looking for causes and an origin. This took me to ever longer cycles (years, hundred then thousands and more years) until I got nature's hint and said "what if the fundamental cycle is assumed to be the universal oscillation?" and that really opened up a whole heap of stuff that worked.
