Correct.

What can you not see MJ?
You have told me that you are working with an imaginary casing line. Since you created the line then you should be able to see what it is you started with.

Of course not...I'm not allowed up there to measure. The numbers I use are from Petrie as I have explained over and over again.

Simple
I'm confident that Petrie knew something was odd with the measures. You may have noticed that he never entered the "actual" height of G2...very odd of him to miss this important measure, but I'm betting that he did know the value because it's simple to determine from the top of G1 with his instrument. Plus he ventures to the identical level several years later to confirm.
Soooo...what did he do?
After measuring the height of G2 he climbed to the top of G1 at the very location that is equal to the "truncated" height of G2.
Then he "shot" a line to G2 from G1 to determine their difference in height above sea level..! The easiest and most accurate method.
Course 201 of G1 is 262Rc above base...identical to the truncated height of G2.

Think of the above. You being the designer of the structures, which of G1 or G2 and at what point do you think others would climb to "compare" their height?
Answer..
a) It has to be G1 (G2 is higher)
b) Must shoot a line from a known height of G2...the height of it's present truncated apex.

The ratio of 4/pi is set at the base and from it you derive a set of measures...those that have been published for centuries.
However, if you don't believe the numbers true then you climb to the top and measure to confirm. It is here that you discover the builders did a fast one on us, they designed a secondary angle within the primary angle for a secondary reason.
The base angle og G2 provides 280 height, but the 5:4 top angle provides a 275 height...identical to G2 if it were constructed on a 4:3 ratio.
Now we move over to G2 and use the 4:pi ratio from G1 along with it's base measure of 411.3Rc and discover that the height would reach 262Rc...the "exact" height of its truncated apex as witnessed today and the exact location that Petrie selected...course 201 of G1.

The 70" was an approximation from memory...the drawing shows the exact numbers as you have calculated.

Actually there are other layers missing, but how many will always be a mystery, unless the original design/plan is discovered.
I believe, from the measures of G2 that the truncated apex of G1 was ceased at the 267 Rc level (course #206)...but it is impossible to prove.
Best.
