If they divided the indentation into quarter cubits then the closest they could get conceptually is 1759/560. I imagine they probably knew 22/7 was closer to pi than 25/8, though I agree it would be too much to expect them to know which division came closest.
I'm still working on 3927/1250!'
3927/1250 is a brilliant version of 3.1416 and I have been looking for it for ages. thanks.
3927 is a variable version of the metre and the metre has a fixed relationship with the cubit ( also a variable length unit)
cubit x 1.9008 = metre
20.65972222 x 1.9008 = 39.37.
Now this cubit looks hopeless but I feel sure it would look great if properly fractionalised.(see last line)
The cubit can have a fixed relationship to the GP base x 1760
20.65972222 x 1760 = 36361.11111 imperial inches.
My theory is that 100 imperial inches represents one solar day at the GP base level subject to GP height using 1760/280 where 1760 and 280 are variable cubit lengths.
so there are 363.6111r solar days being represented.
Another part of the theory is that Michell's canon of ancient measure is built into the G1 design.
Using the canon
363.1111r x 360 x 1000 = 130900000 imperial feet this is 24791.66667 imperial miles
Also the theory suggests that 25000 miles is the ultimate base 100 design
25000 - 24791.66667 = 208.3333333
208.3333333 x 5280 = 1100000 imperial feet.
Also part of the theory is that 20.8333r is the base 100 cubit length in inches
1760 x 20.8333r = 36666.666r 1 solar year.
So 39.37 is an extremely significant number because of what the theory produces in terms of the 1100000 feet using the canon.
Diving 39.60 by 1.9008 produces a cubit of 20.8333r so the fixed cubit to metre relationship holds within the theory.
19008 feet is 3.60 imperial miles.
20.65972222 is 1859375 / 9000 which is 74375/3600 this is 2975 / 144 so yes it looks pretty good.
If 39.60 is represented by 132000000 (25000 miles)
then 39.27 is represented by 130900000 (24791.66667 miles)
Difference in feet is 1100000
As 132000000/ 3960 = 33333.33333 x 3927 = 130900000
The unit iof translation is base 100.
This is what Thom tells us to look out for.
Finally 2975 is a base 17 unit and this is Thom's system.
