THE RESULT
What the data shows
The largest computed metric is 4,328 for Single record; the smallest is 2,169 for Repeated with same score. Metric: source_rows (Source rows).
No batch identifiers are supplied; identical inputs need not be duplicate ingestion errors.
| signature class | signatures | source rows |
|---|---|---|
| Repeated with same score | 992 | 2,169 |
| Single record | 4,328 | 4,328 |
THE METHOD
From source to answer
Group exact predictor signatures and count score multiplicity without treating repeated rows as proven errors.
The Python source exposes this study’s transformations. The complete project download includes shared preparation and evaluation routines.
THE NEXT DECISION
What follows from the finding
Preserve input groups in evaluation and investigate the meaning of repeats before deduplicating.
Where the conclusion stops
Sensory scores are ordinal and concentrated in the middle. Producer and batch IDs are unavailable. Associations are not recipes for changing quality or evidence of market price.
Related studies may reuse observations or holdouts. These are historical analyses; associations and backtests do not demonstrate commercial impact. Further model tuning needs new, untouched evaluation data.
