I am familiar with some of the more complex numbers you have posted but want to keep this to your geometric model at the mo if that is OK.
There is a condition attached to your calculation and it is that the diameter to circumference relationship must be 22/7 otherwise your calculation does not work, use any other version of Pi and it is kaput.
I looked at it in detail last night and it is a single version Pi calculation. That does not take anything away from it, it adds to it becase it is rational and evidence of the smoothing of the geometric relationships using conscious thought on a fractional level. There is a system at work. it is brilliant they put put their designs very accurately on any azimuth they chose, be it the rising Sun or moon of true North.
