Gantenbrink is wrong in the numbering of the courses - Petrie's data on the numbering and elevation of the courses is of course correct - but apart from that, Gantenbrink is right about the overall geometry of the shafts, being based on whole palm sekeds. This system is, however, theoretical. In this system, both upper shafts exit at the same elevation, 154 cubits above the base. This happens to be at the top of course 104.

In actuality, the KCS shaft exits, roughly (for the middle of the shaft), at the top of course 103, 9 palms below, while the KCN shaft exits, accurately (for the bottom of the shaft), at the top of course 102, 10 palms below this.

In searching for an explanation for these shifts from the "perfect" level of 154c above the base, it will be discovered that the top of course 103, which the KCS shaft (middle) seemingly targets, has a horizontal length of 200 cubits. I encourage everyone to do the maths on this.
