Fairness report
Over a 12-week cycle Ana carries 34 effort points, Ben 31 and Cal 41 — because the heaviest chore lands on Cal's slot more often than the rotation suggests.
How the Chore Rotation Fairness Checker works
- List the children and every chore with an effort weight.
- Set the cycle length, then check the totals over the full cycle rather than one week.
- Adjust the rotation offset if the totals differ. A rotation is only fair if the cycle length divides evenly by the number of children.
The method
A rotation is fair over a cycle only when every child holds every slot the same number of times.
unfairness appears when cycle length is not a multiple of the number of children
With three children and a four-week cycle, one child gets the heavy chore twice as often — which is invisible weekly and obvious by half term.
FAQ
Why does a rotation drift out of fairness?
Because the cycle length and the number of children often do not divide evenly. With three children and a fortnightly heavy chore, one child gets it disproportionately, and the pattern only shows over months.
Should chores be weighted?
Yes. Rotating tasks of very different effort as though they were equal produces a rotation that is technically even and obviously unfair, which children work out quickly.
What about age differences?
Weight the chores by what is reasonable for each child rather than trying to equalise raw totals. A fairness check on unequal capacity gives an answer nobody accepts.
