If you enter 1 or 10 or 100 in the 'yearly increment' box, results will be displayed by year, decade or century –
for any era you enter into the 'minimum' and 'maximum' year boxes.
The latitude of the Tropic accelerates and decelerates in annual ground-speed. See pg.32.
See pg. 252 for increase in annual rate-of-speed between 3976 BC and A.D.1865.
The Tropic now moves southward at its most-rapid speed of about 48 feet per year.
A theoretical current Royal Cubit value would now be 28.8".
I did not say that 'eccentricity' is relevant to 'obliquity.'
The distance of the average Stride of Re measured ~412.245" during the construction of the Khufu, (pg. 256)
which is the reason for the length of the King's Chamber. This length's division by twenty, to Royal Cubits,
gives a cubit-length of 20.61277" – the fraction a result of the division expressed in the imperial system of measure.
The "Followings of Horus", the determination of the position of the northern Tropic, were recorded on the Palermo Stone
to the reign of Hor-Aha. (c.3200 BC). I imagine the AE were able to figure out exactly how the Tropic traveled over
several centuries, if not millennia, of empirical observation.
See pgs. 44 – 50 re. how to specify the chronology of the First Dynasty and Year of Unification from the record of
the "Following of Horus on the riverbank", from the Palermo Stone's record of the second year of Semerkhet.
