STR.6:5.4.1 - Develop a variation for the selected contribution

The diagnostic contribution remains selected. The team applies two output variants to the six records. A returns the comparable error/acceptable pairs E1–N1 and E2–N2. B returns those pairs and retains E3 and N3 with their source times and missing-reference flags. The difference can be inspected in the output; it is not a claim that either variant explains the errors.

A supplied planning estimate gives B five minutes more review work than A. Retaining B’s small output and its linking rule is nevertheless worthwhile for one identified continuation: determining whether setup records for 09:40 and 11:15 can recover the missing conditions. The preserved material makes that question specific. It does not make B preferable for every comparison or allocate the later records inquiry. Another practitioner also needs permitted inputs and the capability to carry out that inquiry.

If the existing pairs already provide an adequate specialist answer to the current question and the missing intervals cannot change it, use that answer. Do not construct B merely to enlarge the retained set.
