Clarification for “Price comparisons: compare like-for-like information”: the point beginning “Identify those fields using legitimate product information and distinguish…” 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: scope. Keep the stated question separate from any broader claim.

Method note for “Price comparisons: compare like-for-like information”: use “Identify those fields using legitimate product information and distinguish…” 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. Keep the stated question separate from any broader claim.
