You've stated yourself above at 01:26pm that you only think the 104m is 'probably' the current height, therefore you do not know, therefore your methodology is flawed.

In addition, the star shafts are indeed star shafts, and are orientated to allow the pharaoh's soul to ascend to the northern and southern regions of the sky, which they thought were important. That's what it says in the Pyramid Texts, which you chose to ignore entirely in typical extreme skeptic fashion.

You started with a pre-conceived conclusion, and ignored the most important texts of all because they didn't agree with your conclusions.

This is classic case of "tendency criticism", a flawed methodology originating in 19th century Germany. You decide the tendency, then shape the evidence around the theory.

Thank goodness for Petrie and others who tied the interpretations to the fact.

My methodology is quite correct, and to date I still consider that there is no definitive value for the design slope of the Red Pyramid precisely BECAUSE there are so many conflicting figures.
