I don't think Jim and I are as hung up on pi at the GP as you seem to think we are. in terms of the GP design I am more than happy with 44/7 or 1760/280 and accept Jacob's explanations.
I am more interested in putting a circle around Jacobs square of 8 units being 8 x 1.111r = 8.888r x 1.111r = 9.87654321.
now I know Jacob has found 1.41414141r as 140.99 as well as 99/70 the evidence for 9801/9800 is established.
99/70 x 9800/9801= 140/99 no loose ends.
n/(n-1) Jacob has this also The two faint lines too close to the sekhed to call are definitely known to the designers.
