STR.9:5.2 - The criterion can change the answer even when the numbers do not

In a separate constructed public-service comparison, assume two configurations satisfy the supplied protected-access condition. A qualified model for this illustrative use gives the following waiting times under two stated demand conditions; neither condition has an assigned probability.

If the responsible chooser minimizes the worst waiting time, A is preferable: 12 rather than 16 minutes. If the declared criterion instead minimizes maximum regret in waiting time, the best result in condition 1 is 4 and in condition 2 is 12. A’s regrets are 6 and 0; B’s are 0 and 4. B then has the smaller maximum regret, 4 rather than 6.

Neither calculation changes the stipulated waiting-time estimates or selects the public value rule. The practitioner returns the consequence of each rule for the responsible judgement. If B failed the protected-access condition, its smaller regret would not make it eligible. The example demonstrates a comparison distinction, not a public-policy prescription or a validated forecast.
