141.4285714... miles = (99/70 x 100)
(99/70 x 100) / 45/22 = 69 1/7
69 1/7 x 360 = 24891 3/7 Earth Equatorial Circumference. '

this calc is absolutely stellar, everything falls into place. Does this mean they actually calculated it as 24891 and 3/7? and the design of the GP is based on this rather than our current 24901.5? It is a bit weird that i am getting 365.2 and 365.222r as potential candidates for this dimension as 24900 and 24901.5. I can definitely go with your calculation and explain why it works. It just leaves the problem of the other two calcs but perhaps there will be an explanation.
great stuff Jacob have you written a book about this? If so where can I get it? Definitely using the imperial system so they were!
I notice you have 52.1cm in your analysis, this is a very significant number in my analysis, have you used it at all?
