Parts 1 to 5 apply the five formulas of the rules. A measure is also given for many single points: a sentence in brackets, beginning "In practice", that tells how that point can be measured in a real society. This part works out the further ones for the same seven societies, in the order in which they appear. Each is set out in the same way: the measure as written and what it measures in plain words; and, where it is measured, how we measured it and what the seven societies show, and, where one measure bears on another, how the two connect.
