How can this be 'lacking in substance' when my sources are the dimensions of the Pyramid itself and the EMP?
Let's face it, Don, your own hypotheses are built on even less!
Perhaps you can elucidate.
That choosing 280 cubits because there are 28 digits in a cubit makes absolutely no sense to you is irrelevant.
It makes no sense to me, either - but this is simply because non of us are 4th dynasty Egyptians.
I presume you think the same for: 220rc because there are 22 digits in seked 5-1/2's horizontal run.
I fail to see how: 'the Pyramid's vertical height is in royal cubits 10 times the number of digits in the rise of seked 5-1/2 = 28rc x 10 = 280rc' becomes 280 x 28 = 7840.
Perhaps you can explain it.
As for your, 'So in my opinion you have yet to address the initial question, why 440 cubits.'
I have answered your question soundly and fully; it's now just a case of you don't agree with it because it runs contrary to your own views and beliefs about Giza, etc.
So few answers - and not one of them mine.
