This has been noted on other threads in particular what happens when 10 is used as a diameter because the UOIO has to be deducted from it.( the zig zag line with 10 peaks)
10 - UOIO = 8.8888r squared = 79.01234568 being 25 units of Egyptian pi a unit of area.
If 79.01234568 is divided by 9.87654321 the result is 8 and we have 25/8 as Geoff has found.
9.87654321 is hidden
8.8888r x 1.111r = 9.87654321.
The whole system reveals itself and is found in the GP design using 22/7 and 22/7 x 9800/9801.
It is very complicated.
If you look at my book 'Proving the Megalithic Foot' this system is identified in the book as part of the proof.
The megalithic foot x 16500/16499 is the version of root 2 used within this Egyptian model being 99/70 and Peter Harris' work is UK centric.
