It audits its own rule and finds the rise came from where it moved the finish line, not from the buses: 41 late journeys were ended early and counted as punctual, and on 12 of them passengers were left at a shelter. The fix costs the operator a 6,000-pound bonus. A story about a measure that goes up for the wrong reason, a driver who quietly covered for it, and reporting the number you would rather not.

The treasurer plants 40 known errors without telling it and it finds 23. It finds 2 of the 14 that its own reading would also have made, because it read the scan the same way and took the agreement for confirmation.

The agent has the permission to do it. It finds, instead, that the book has been short on exactly the nights a rounding rule would predict, which means a colleague was questioned for nothing, and that the only way to say so is to leave the wrong number standing beside the right one.
