One idea I have tested is that the numbers for bread and beer may be fractions. They are most obviously the things that are consumed by mouth and the mouth symbol ( r1 ) is used to indicate fractions in the vicinity of a number. The Egyptians were also fond of unit fractions and sums there of.
So could the 1000 loaves be referring to 1/1000 and the 100 jars of beer be referring to 1/100. The sum of these two fractions would be 0.011 in decimal notation.
I haven’t identified anything of significance with respect to Saturn with this number. However, when considering the 2800-12-02 BCE date I identified previously, 0.011 multiplied by 1760 the base perimeter of the pyramid gives 19.36 very close to the number of years to the July 2781 BCE date for the synchronisation of the heliacal rise of Sirius and the Egyptian civil calendar otherwise known as the Sothic cycle.
