Hello Hermione,

I wrote, 'That the perimeter of a square is always 4 times the length of a side is not mentioned (AFAIAA) in any of the Mathematical Papyri, so are we then to assume that the AEs did not know: Perimeter of a square = 4 times length of a side?'

You reply, 'That is a simple, self-evident mathematical fact.'

If a square measures 4.743 units, then what is its perimeter?
Now, you can either physically do a continuous measure of the perimeter or you can calculate it as P = length of side @ 4.743 units time 4.
The thing here about the irrational number pi is that strictly speaking it cannot be physically measured.
However, what can be done and is still done to this day - and this despite our clever, highly advanced technology and mathematics - is to take the circumference of a circle to be approximately 3 1/7 times the diameter of that circle.
Various people in various parts of the world drew a circle (usually, I imagine, with a couple of pegs and a piece of cord, string, or whatever) and then did a continuous measure of the circumference - eventually various people in various parts of the world twigged that the circumference of a circle is always approximately 3 1/7 times the diameter.
Given that their royal cubit was divided into 7 palms, I expect that the AEs were amongst the first to do said twigging...

You write, 'A knowledge of pi is, OTOH, more complex. So I therefore don't see how your argument could be used to imply that the AE realized the significance of the ratio 22/7.'

Well, the point is that pi and 3 1/7 are quite simply not, repeat not, the same thing.
Pi is significant because it is an irrational number, and so on and so forth.
3 1/7 is totally insignificant.
3 1/7 as the ratio of diameter-to-circumference has no more significance than has a square’s perimeter being 4 times the length of one of its sides.

Saying that multiplication and division by 3 1/7 (22/7) was used in the planning of the dimensions of Khufu’s pyramid and its passages and chambers is not saying that the planning of the Pyramid's dimensions involved pi.

You write, 'Without a sight of all the evidence - presumably the material in the 300 pages that you've already mentioned - I don't think I could comment further on this.'

Fair comment - and you presume correctly.
Until I am ready to present my hypothesis, I strongly recommend that you and others here several times each and every day repeat to yourself: 3 1/7 is not pi. Pi is not 3 1/7.
