Apologies for the delay in reply. In his paper “ THE RAMESSIDE STAR CLOCKS AND THE ANCIENT EGYPTIAN CONSTELLATIONS”, Juan Antonio Belmonte leveraged a method to convert observations from the star clocks into R.A. And uses those R.A. Figures to map the Egyptian skies. This paper is a predecessor to the paper by Lull and Belmonte that I reference heavily in my work. If I recall correctly the method used determines RA within 20 minutes.
Specifically with reference to the loaves of bread, in the Nederhof translation, the hieroglyph used is Gardiner X1 which is commonly expressed as a semicircle a bit like the rising sun. There is evidence that yeast was used in baking back to the old kingdom meaning this could represent A slice through something like a round bun or cob loaf rather than a flat bread. Such a loaf would be a good physical representation or model of half an oblate sphere. The earth is not perfectly spherical but is an oblate sphere.
There is quite a bit of speculation here but that is the line of thinking I was heading down.
