Facts can "change" depending upon who is perceiving them.

The Egyptians had no idea what a degree was, so they wouldn't know 26* from 27*... nor did they probably care. The average builder in the Old Kingdom likely would have lumped them both into a simple 2:1 rise over run, or seqed 3 1/2.

And, once again, the degree of coincidence does not change the nature of a coincidence. Forgetting that leads us into all kinds of conspiracy-type theories.
