Bunch Compactness Index Classifier

Audit measured berry solid-volume/cluster-envelope packing proxy under caller compactness bands; no universal OIV score, overlap correction or rot susceptibility prediction.

Description

Berry volume relative to a cluster envelope gives a packing proxy.

Berry volume relative to a cluster envelope gives a packing proxy. It differs from a universal visual compactness scale.

Audit measured berry solid-volume/cluster-envelope packing proxy under caller compactness bands; no universal OIV score, overlap correction or rot susceptibility prediction.

When to use Bunch Compactness Index Classifier

Use this tool to audit measured berry solid-volume/cluster-envelope packing proxy under caller compactness bands; no universal OIV score, overlap correction or rot susceptibility prediction.

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 Bunch Compactness Index Classifier 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 clusterBerryCounts, meanBerryVolumesCm3, measuredClusterEnvelopeVolumesCm3, callerPackingLowerEdges using the field table and calculation rules, then run the tool.
Read observedBerryPackingFractions, callerCompactnessClassCodes. 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
clusterBerryCounts	Cluster berry counts	list of number	Required
meanBerryVolumesCm3	Mean berry volumes cm3	list of number	Required
measuredClusterEnvelopeVolumesCm3	Measured cluster envelope volumes cm3	list of number	Required
callerPackingLowerEdges	Caller packing lower edges	list of number	Required

Align nonnegative integer counts, nonnegative berry volumes and positive envelope volumes. Require inferred fractions in [0,1]. Assign zero-based codes from increasing covering lower edges, with equality entering the new band.^[1]

Paired lists must be nonempty and have equal lengths.

packing fraction = berry count × mean berry volume/cluster envelope volume

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
observedBerryPackingFractions	Observed berry packing fractions	list of number
callerCompactnessClassCodes	Caller compactness class codes	list of number

Limitations and assumptions

No OIV grade, overlap correction or rot-risk prediction is implied.

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 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.
