A practical checklist

  1. Compare the original records, dates, units, and job references.
  2. Ask whether the figures describe different sections or one corrected measurement.
  3. Update confirmed details and explain the resolution; preserve uncertainty if evidence remains incomplete.
Illustrative recordA worked example

One note says 12 t and another 14 t for load 9. The scale slip confirms 12.6 t. The record is corrected and notes identify the slip as the resolving source rather than averaging the two earlier figures.

What to avoid

Averaging conflicting numbers creates a third unsupported number. If no reliable source exists, label the quantity as unresolved instead.
