Calculating Blood Taints

The Blood-Taint for a child is calculated by averaging the blood-taints of its parents. As an example, see the calculation of Carnelian’s blood-taint.

To my surprise, when I worked out the general form for a blood-taint, I discovered that, because of the way in which all Chosen blood-taints ultimately derive from a God-Emperor, every such taint can be expressed as an odd number divided by a power of 2 as is shown in the calculations displayed.
