Hi Alex,

The main basis for your revised OK dates seems to be this :

"Analysis of texts and iconographic sources suggests the the precise temporal marker in the orientation procedure was the specific configuration of Meskhetiu, namely the horizontal alignment of its two outer stars, Dubhe and Alkaid. The alignment brought Meskhetiu into a "state of balance"

But there is a big assumption here that the Meskhetiu orientations seen on tomb ceilings were the same as those used in setting out pyramid bases at the start of the construction stage.

The tomb ceilings were to do with calendars and Sed Festivals.

The 'big assumption' is very weak, yet is the main evidence for the redating ?
