Comparing candidate orders
| Observation | Next useful move |
|---|---|
| The sequence is readable but a necessary relation disappears. | Restore that relation or change the order. |
| The order has a name but readers infer the wrong dependency. | Repair the passage itself; the label has not solved the problem. |
| The reader recovers the relations needed for this use. | Keep the sequence unless a worthwhile improvement is available. |
| The route will be reused with different material or readers. | Compare relevant changed cases; retain the conditions under which the order works. |
Use NSTD.6 when a qualified quality result is needed. The number of worked examples alone does not determine an ordering-quality value.
