I have only one question for you. Just what is your objective with these numerations, diagrams and coordinates? That is a customary way of introducing your data I think. Not plastering a message board with such figures and no explanations concerning them. Doing a comprehensible presentation is difficult enough without such displays as yours. That said, I will continue with mine now.
To be honest, I can't really explain how all of the operations involved in my last calculation produce a precise value for the Equatorial Radius of the Earth, when filtered through that Old Meter value of 39.375 ins. I work more on intuition than logic sometimes, and just recognize certain values of figures when I see them. Like I said previously, I'm working a lot of these equations backwards and upside down on numerator, denominators, etc. I could have done what is a proper Radian calculation and divided 180* / by 57.375* to obtain a very distorted Pi value of 3.137254902, and then adjusted that by the 561/560 ratio of Polar/Equatorial Circs. = 22/7 Pi once more. But to quote the late great Bruce Lee, "Whatever works, use it!"
One of the best ratios I have discovered applicable to the Earth dimension model I have been putting together over the years is one that John Michell devoted a lot of attention and discussion in his early books, of 1225/1224 and it's inverse. The first figure is well known as a magic square of 7, or 1-49 = 1225, and the other 1224 is useful in many geometric calculations. I don't think I need to remind anyone again how I used that ratio to obtain the Old Meter value of the Speed of Light, so I will now use to again on the Polar Meridian Circ. value I obtained long ago as 12/7 ratio AE Cubits of 8750^2 = 76,562,500 units x 1224/1225 = 76,500,000 Equatorial units. But in this case, the unit is the 12/7 x 385/384 variety, more commonly known as 20 5/8th. ins. or 20.625 ins. AE RC. That is because in order to balance the differential between Polar and Equatorial Circ., the ratio 561/560 is employed as (385/384)/(561/560) = 1225/1224. That makes a good rational for creating these particular unit variations, don't you think?
Another useful function of the 1225/1224 ratio, is in adjusting the frequency of the Speed of Light divided by the Polar Meridian Circ. = 7.5 secs. x 1224/1225 = 7.493877551 cycles per sec. However, as before, this figure requires adjustment by that same Polar/Equatorial differential ratio 561/560 for the Equatorial frequency rate as 576/77 = 7.480519481 cycles per second. This band of ELF frequencies are commonly called Telluric currents that were once used to help transmit telegraph signals over long distances without the need of electric generators. One hears a lot these days about the Schumann Resonance frequency of the Earth being 7.83 cycles per sec., which I have discovered is also valid. That rate corresponds to the height of the densest layer of free electrons for radio frequencies to bounce off in the Ionosphere at around 177.6 Mi. above our heads according to Wiki's definition of the Ionosphere found here.
One has to keep in mind in these investigations, that what we call Light, is just a fraction of the Electromagnetic spectrum visible to our eye, but that any part of this spectrum has the potential to travel at the same rate of speed as Light waves.
All very interesting information, but I don't know if it will ever be able to solve this mystery yet, LOL!
