Berries Per Cluster Average Count
Count all observed mature/small berries by cluster and retain abortion-opportunity fruit-set denominator; no inferred original flowers from surviving berries or disease diagnosis.
Description
Surviving mature and small berries are distinct from aborted flower opportunities.
Surviving mature and small berries are distinct from aborted flower opportunities. Fruit-set fraction needs that broader observed denominator.
Count all observed mature/small berries by cluster and retain abortion-opportunity fruit-set denominator; no inferred original flowers from surviving berries or disease diagnosis.
When to use Berries Per Cluster Average Count
Use this tool to count all observed mature/small berries by cluster and retain abortion-opportunity fruit-set denominator; no inferred original flowers from surviving berries or disease diagnosis.
Prepare vineyard measurements, dates or block records for the intended growing period. Keep weights, counts and weather observations in the stated units.
How to use Berries Per Cluster Average Count and understand its results
- Prepare vineyard measurements, dates or block records for the intended growing period. Keep weights, counts and weather observations in the stated units.
- Enter matureBerryCountsByCluster, smallBerryCountsByCluster, abortedFlowerCountsByCluster using the field table and calculation rules, then run the tool.
- Read observedBerriesPerCluster, meanObservedBerriesPerCluster, flowerOpportunityFruitSetFraction. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| matureBerryCountsByCluster | Mature berry counts by cluster | list of number | Required |
| smallBerryCountsByCluster | Small berry counts by cluster | list of number | Required |
| abortedFlowerCountsByCluster | Aborted flower counts by cluster | list of number | Required |
Align nonnegative integer counts by cluster. Return total observed berries per cluster, their mean and pooled fruit-set fraction, requiring positive total opportunities.1
Paired lists must be nonempty and have equal lengths.
fruit set = total mature and small berries/(those berries + aborted flowers) Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| observedBerriesPerCluster | Observed berries per cluster | list of number |
| meanObservedBerriesPerCluster | Mean observed berries per cluster | number |
| flowerOpportunityFruitSetFraction | Flower opportunity fruit set fraction | number |

}Limitations and assumptions
Original flowers are not inferred from surviving berries, and counts do not diagnose disease.
Numbers and computed results must be finite; overflow produces an error. Numeric lists are limited to 100,000 entries; the rules above may require smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use Millerandage Hens Chicks Percent: Count observed small berries under caller diameter policy with explicit assessable coverage; small berries alone do not establish millerandage, cause or commercial grade. For a complementary task, use Berry Average Weight From Sample: Pool counted berry subsamples with independent container tare and unequal berry denominators; not a variety average or equal-sample mean.
