True, it doesn't matter that we have certain things that indicate some supernal math abilities by the ancients, it only matters if we can replicate them. I can certainly look at the height of the pyramid against its base and see pi, but how to replicate it?
I can look at the dimensions of the upper and middle chamber and see indications of 360deg and parts of a circle both less than and greater than 360deg, not just as degrees but also inch measures, but how to replicate them?
I can look at the entrance glyph and see simple formulas associated with a circle and a square and indicating pi, but how to replicate it?
I investigate and research and analyze and put together a theory about the pyramid and a couple of its plans and can replicate that over and over again where the pyramid references the cosmos and Earth and circles and pi and phi, but I can't at all say how they did it.
In all these, something is always missing, and it is the book of how they did it all...you may be right...it doesn't matter that we have the thing right before us that says 'yes'; it only matters if there is more than the thing...if there is a book saying how they did it...hmm...quite true...never believe your own eyes as they don't know what they are describing when the eyes can assess something down to its parts. If there are no instructions, the thing does not exist.
I wonder how the ancient Greeks felt that they could not see the parts of an atom let alone the atom, and yet it took over 2,000 years before they were proved right. NOt a fair comparison at all, I admit, but they didn't even have an atom to see to describe...we at least have the pyramid itself.
You say there is a problem with fractions being used to define small parts of numbers, and I do like 628/200 + 1/628 as a good fraction for pi...probably a better formula just as simple to use does exist. That is an easy fraction that can be broken down into a string of fractions ala Egypt style. That fraction doesn't exist though as it isn't recorded in the very few papyri that we refer to as the compendium of ancient Egypt math and astronomy skills. A culture lasting several thousand years only has a few papyri left to show how advanced they weren't. Hmm...does there seem to be a slight problem with not accepting a high culture based upon a lack of written records despite the large edifices they built?
I guess I'll wait to see if anyone does enter the void found by a muon scan technique and wonder how it equates to my analysis identifying where the winter solstice sun is at noon...where the same sun is one hour before dawn in the intersection of descending and ascending passages...why Sirius and Canopus equate to the middle chamber and its niche and the half height of the pyramid...and why the height references the summer solstice sun at dawn. I'll wait because the book might be in that void, and it might show how they did it when we can already see it.
Well, I'll back off now. I don't have a papyrus to point at and say 'See'. All I have is the pyramid to point at.
Cheers and all the best with not-pi
