The other error in the general summary is the beginning of ascending passage height measure of 179.9".(It should be 172.9")

Unfortunately John Romer uses this measure in his book " The Great Pyramid."
calling it 8.73 cubits.

e.g. Page 341.

"For this provides a size for the grid offset measurement of 8.73 c, which once again is well within the existing parameters in the pyramid, and in fact is identical to the dimension of the grid offset at the prism point."
( His prism point is the beginning of the ascending passage. )
