Bad habit of yours reading only what you want and choosing what you think is supporting evidence.
Nothing new under the sun.
the other value was 411.122 RC which equals 8477.33564 inches.
Now you posted 8474.9 inches. That is only 2.44 inches off.
But I did say I could adjust it for you and I keep my word.
I will use your style of "amazing" discovery mathematics.
Let's see The actual "Petrie length was 8474.9 and mine was 8477.33564. Ok DB style #1:
I suggest that Petrie was mistaken!
DB STyle #2: 8474.9 * 100 * 22/7 / 354(LY) / 365(SY) = 20.614" RC just, now this is TRULY amazing, 0.001" YES that's right 1/1000 of an inch off Petrie's RC range of length. Divine RA!!!!
So to reiterate: the BFD cubit * SY * LY /(22/7) / 100 =
8474.8839 inches an error of only, now get this, 0.0161 inches.
DB Style#3: I need it to equal 8474.9 sooooo * 100 * pi / 354 / 20.62 = 364.74 = 365 days for solar year!! Accurate
Any other denying? My values work period. Well at least within the tolerances of your M.O.
365 * 354 / (22/7) / 100 * 20.615 = 8475.3"
That's only 0.4 inches off Petrie's value and I can use the "ersosion" error margin to help cover that value.
Check your math.
Treat the earth well, It was not given to you by your parents, It was loaned to you by your children.
