Case 47 — A durable glossary entry for an ambiguous abbreviation · source wording exercise

Reader check for “A durable glossary entry for an ambiguous abbreviation”: distinguish the discussion point “Add a cross-reference for alternate meanings rather than assuming that every…” from its proposed application. The thread offers a way to reason about the question, without adding a personal experience or a newly observed outcome. Review focus: source wording. Retain the source wording beside any paraphrase.

Case 48 — Certificate of analysis: which claim does each measurement support? · source wording exercise

Clarification for “Certificate of analysis: which claim does each measurement support?”: the point beginning “A percentage without its method and sample linkage cannot…” belongs to the question as written. It should not be read as a report that a new check, purchase or experiment has been completed. Review focus: source wording. Retain the source wording beside any paraphrase.

Case 48 — Certificate of analysis: which claim does each measurement support? · source wording exercise

Method note for “Certificate of analysis: which claim does each measurement support?”: use “A percentage without its method and sample linkage cannot…” as a row heading in a proposed working record. Put the statement, its supporting source or measurement, and any unresolved detail in separate fields. This proposes a format; it supplies no additional evidence. Retain the source wording beside any paraphrase.

Case 48 — Certificate of analysis: which claim does each measurement support? · source wording exercise

Limit of the answer in “Certificate of analysis: which claim does each measurement support?”: “A percentage without its method and sample linkage cannot…” is an excerpt from the discussion, not an independent verification. A reader needs the relevant original material before treating an interpretation as established. Review focus: source wording. Retain the source wording beside any paraphrase.

Case 48 — Certificate of analysis: which claim does each measurement support? · source wording exercise

Correction note for “Certificate of analysis: which claim does each measurement support?”: retain the wording beginning “A percentage without its method and sample linkage cannot…” in the record. If later material changes it, add the date, the changed wording and the source for that change; do not invent a completed correction here. Retain the source wording beside any paraphrase.

Case 48 — Certificate of analysis: which claim does each measurement support? · source wording exercise

Summary draft for “Certificate of analysis: which claim does each measurement support?”: the answer addresses “A percentage without its method and sample linkage cannot…”; the related point is “Ask whether the sample identifier, issuing laboratory, report date and…”. Keep both connected to the opening question, and mark any conclusion needing further records as unresolved. Review focus: source wording. Retain the source wording beside any paraphrase.

Case 49 — Two laboratories, two percentages: are they measuring the same thing? · comparison exercise

A comparison table places chromatographic purity and net peptide content in one column. Both are percentages, but the reports define their denominators differently. How should the table be repaired?

Review focus: comparison. Make the basis of a comparison explicit before interpreting it. Use the original answer fragment “Before comparing laboratories, ask whether sample handling, method conditions…” as the discussion anchor; no new event or result is supplied.

Exercise RESEARCH-26834/49: address this question within its stated limits.
