Of course what I wrote is not imaginary or even unconventional.
It is the historical facts based on what Petrie's surveys and other later scientific survey measured.
Also, I have nowhere, ever, said the ancient Egyptians had pi during the Old Kingdom.
What I have demonstrated, based on archaeological and textual evidence, is that they understood that a diameter 7 palms formed a circle of 44 palms.
They didn't need to be rocket scientist to know that, considering they had been using a 7 part cubit for over a century by the time Giza was built.
In fact it would be far more unbelievable if they didn't know that!
