The RMP is a copy made by the scribe Ahmose during the 15th Dynasty reign of the Hyksos Pharaoh, Apepi I.
Ahmose states that his writings are similar to those of the time of Amenemhet III (1842 - 1797 B.C.)
Similar means not an exact copy!

The Eye of Horus dates from predynastic times.

Not quite so MJ, the AE did everything is in fractions, remember?
20.632 inches = 20 79/125 inches, using fractions of course!
20 79/125 / 448 = 2579/56000 inches = (.046053571 inches)= 1/448 cubit.
(58.6) is 58+3/5 / 2579 /56000 = 3281600/2579 = 1272+1112/2579 digits that is 1272 + 1/4 + 1/6 + 1/76 + 1/741 + 1/1274026 digits, Not the 1,273.91 you calculated. But that is using decimals and presents a very good example of why the AE used unit fractions as they are definitely more accurate. The figures for the second through tenth courses are?

LOL, It sure could! Not likely, but it could. So now that we are measuring in 1/8 digit increments, express that in a seked ratio in Egyptian fraction form.

Not really, if it were full digits it might mean something.
Southwest corner: 57 3/5 / 2579/56000 = 1250+1850/2579
Average two corners,
57 3/5 + 58 3/5 = 116 1/5 / 2 = 58 1/10
58 1/10 / 2579/56000 = 1261 1481/2579 digits
Egyptian Fraction: 1261 + 1/2+1/14+1/354+1/6390762 digits.

I don't see you posting in Egyptian Fractions, and it is not worth the effort for something I knew they was wrong to begin with. You will come to understand the decimal system just will not work with Ancient Egyptian mathematics. But if you want to calculate in decimals it is ok with me.

Thank you
