Acceptance rubric
An SSR re-run acceptably reproduces this benchmark when it clears every check below on the same 4 paired questions the source publishes. The chip badges name the checks the round-38 → round-46 shape-mismatch finding argued are necessary but not sufficient in isolation.

What this benchmark discloses
Recruitment screener (verbatim)
Recruited by gender, age, and dark-chocolate consumption frequency. Excluded: allergy, restrictive diet, vulnerable persons, pregnant women. Source: Visalli et al. (2022), PMC9679663.
Sample weighting & demographics
Unweighted hedonic. 9-point discrete scale, single rating per product per consumer. Anchor labels not in the paper body — pending .xlsx codebook inspection.
Fieldwork dates, country, language
Dijon and vicinity, France. Specific collection dates not published in PMC9679663. Mendeley release: 2022-10-03.
Original question text & translations
On a scale of 1 to 9, how do you like this chocolate? — single hedonic rating per chocolate per consumer. Source: questionnaire.pdf p.18 (Mendeley fshtbhffth/1). Screen [7] reused for chocolate per q.txt:162-163 ("Same as screens 4 to 12 with chocolate").
Likert / scale labelling
9-point discrete checkbox scale, end-anchored only. Anchor 1 = "I did not like it at all". Anchor 9 = "I liked it very much". Points 2-8 unlabelled (equal-interval assumption).
FGI moderator guide & coding rules
Hedonic survey, not FGI. No moderator guide. The temporal methods (TDS, TCATA, AEF, FC-AEF) in the same paper are out of scope for this paired comparison.

SSR score vs ground truth, by question
Each row holds one question. The teal mark and range are SSR. The sky mark and range are the source FGI/survey.
