Hi Graham,

Interesting about the division of the Kochab-Mizar line by the pole. Thanks for suggestion about the 9/11 ratio of the division of the baselength at ground level by the point of intersection of the kc shafts. When I modified my diagram to include this, I also noticed that the northern shaft cuts ground level 121 cubits south of the intersection point of the shafts and 77 cubits north of the southern corner of the pyramid, equal to the division of the baselength at the height of the shaft exit points, by the intersection of the shafts. Take a look and thanks again.

Best,

Jim
