While Thuban would not be at exact north, it would only be within 1 degree off (if you believe what's on the internet), so you'd still need a DP that's at a 29 degree angle.

Which is why I mentioned (semi tongue-in-cheek) the possibility that Giza may have been at 26 degrees latitude in some distant past. I am not as compelled as others to focus on such star alignment because the pyramids along the Nile show a significant spread in their DP angle. Red Pyramid is at 27 degrees, the Bent's satellite is at 32 degrees. Meanwhile, other reasons for such angle include more functional purposes, such as what Jon and Open mind are currently discussing regarding overcoming the coefficient of friction during a mechanical process, similar to the role such a specific angle might play in Steve Clayton's 4.6 degree funicular model.

Whether that's coincidence or not, I don't see a correlation between entrance passage angle and pole star that would allow those pyramids to have been built within 200 years of each other in the 3rd millennium BC when Thuban was the pole star.
How can any of us ever know, when all we can do is think?
