That was an interesting calculation I did yesterday regarding the MY value of the SOL. And the interface ratio of 225/224 as I later discovered is used to convert MY units back to that Octaetis Lunar cycle, and thus AE RC cubits.
Here is what I wrote on your topic of Cracking the Megalithic Code:
<What I failed to observe way back then was this curious feature of this ancient Lunar cycle accounting system. A Lunar Synodic Month calculated as 29.53125 days x 99 months, divided by a Solar Year of 365.25 days Julian Calendar system totals 8.00436345 yrs, Metonic cycle. What is interesting in this case is the fractional remainder of .00436345 part of a year. Divide the total by 8 yrs. and this fraction comes to 1.000545431, so subtract the 1 and multiply the remaining fraction by 365.25 days= .19921875 day x 24hrs. = 4.78125 hrs. This period is a fraction of x 16 = 76.5 hrs., or x 32 = 153 hrs. The relevance of this hr. value should be familiar to some here, as the sq.rt. of 153 = 12.36931688 Lunar Mos. per Solar Year,>
So if I use that interface ratio 225/224 x 2.72 MY = 2.732142857 extension, x the common to royal unit factor 7/4 = 4.78125, I get that fractional hour difference in the Octaetis Lunar 8 year cycle I mention above. But even more interesting than that is if I multiply this fractional part by 12 ins. to get 57.375 ins., and that same Radian value of the SOL in fundamental AE RCs. of 144/7 ins.
I like to see Physics and Astronomy coexisting so agreeably. And why shouldn't they after all. What we regard as observable cycles of the Solar system are just manifestations of the forces of Physics underlying those cycles. So whether these ancient cultures actually knew the SOL or not, is still unknown. But they sure nailed the units necessary to produce meaningful relationships to these forces such as Light and Gravity in their constructions.
