Good to see you posting.
With regards to your comment: "...It would be nice to be credited as the original source for the finding of this ratio ..."
SC:The equation you missed (spotted by my co-author of 'The Giza Prophecy', Gary Osborn) goes like this:
23420 - 17820 = 5,600 years
17820 - 10460 = 7,360 years
This is to say that the intersection point in my diagram splits the Precession Timeline thus 7360:5600 years.
And, as Gary pointed out to me, 7360 / 5600 = 1.314285714285714.
Compare with Pi approximation of 22 / 7 = 3.142857142857143.
And here also.
