Case 39 — Accuracy expectations: is -8 s/d acceptable on an entry-level automatic? · source wording exercise

Summary draft for “Accuracy expectations: is -8 s/d acceptable on an entry-level automatic?”: the answer addresses “Comparing against a phone clock once a day for a week,…”; the related point is “One 24-hour reading isn't, because rate depends on wrist time,…”. 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.
