How do you know it is not Egyptian in origin? I found it traverses the Kings Chamber width to the horizontal length of the Grand Gallery roof to the North Wall of the Kings Chamber which is also 1/28 the 1760 cubit perimeter of G1.
Simply demonstrating how the Ancient Egyptians achieved pi (22/7) results using the 14/11 rise run of G1. The numerical sequence noted in the drawing if multiplied by 10 provides the following: Width of the Kings Chamber 10 cubits x 8 equals the Horizontal Roof Length Grand Gallery 80 cubits divided by 14/11 the rise run of G1 yields 62 6/7 cubits, 440 palms, 1760 digits the perimeter of the North Wall of the Kings Chamber. If this was not intentional it is one amazing coincidence. There are other instances of this formula which it will not publish just yet.
It does confirm the Ancient Egyptian ability to achieve Petrie’s observation of the pi relationship between the North Wall perimeter and the length of the Kings Chamber. 62 6/6 cubits / 20 cubits = 3 1/7 is accomplished without knowledge of the concept we call pi. The Ancient Egyptian did not think in terms of pi as we do! I have said it before and will say it again: "As long as one thinks in terms of pi it is simply not possible to comprehend the intent of the Ancient Egyptians nor significance of the 5 1/2 seked". I first copyrighted this material in 2013 and have advanced the studies in this area enough to actually begin comprehending their intent to a much greater extent.

9.87654321 / 22 x 7 = 3.142536476 / 2.22222r = 1.41414141414r a decimal version of root 2 and very deliberate manipulation.
I am not missing anything, perhaps you can explain the significance of 2 2/9 and where it come from and what aspect of the pyramid does it represent? I have known and demonstrated years ago the rise run of G1's 5 1/2 seked 14/11 x 10/9 = 140/99 as a value for the square root of 2. Simple clean and no jumping through hoops and falls within the above drawing. Perhaps you remember this post from this past January: <[grahamhancock.com];
You wrote: Where you see 22/7 I see two more lines inside 22/7 as 3.142536476 and 22/7 x 9800/9801. Too close together to be visible to the naked eye but there numerically all the same.
Sorry, but you are mistaken, I don't see 22/7 at all, further more I don't believe the Ancient Egyptians did either. Common sense should tell you if 22/7 or any value of remotely resembling pi, was as important as you think it was, surely the Ancient Egyptians would have made at least a note of it somewhere in all of the archived material. But there is nothing, zero, zip, nada regarding pi. All they left for us to study are the cubit, unit fractions, the Eye of Horace and seked and in order to understand their intent it is necessary to think in their terms.
Not to be unkind, but from my perspective you seem to be using unsubstantiated numerical manipulations in order to support your hypothesis. As I see it you, like most, are so wrapped up attempting to prove their use of pi to even investigate let alone comprehend the level of significance of the 5 1/2 seked held by the Ancient Egyptians.
