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.

Description

Small-berry share depends on which berries can be assessed.

Small-berry share depends on which berries can be assessed. Unassessed berries should remain outside the assessed denominator.

Count observed small berries under caller diameter policy with explicit assessable coverage; small berries alone do not establish millerandage, cause or commercial grade.

When to use Millerandage Hens Chicks Percent

Use this tool to count observed small berries under caller diameter policy with explicit assessable coverage; small berries alone do not establish millerandage, cause or commercial grade.

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 Millerandage Hens Chicks Percent 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 measuredBerryDiametersMm, callerSmallBerryDiameterThresholdMm, assessableBerryFlags using the field table and calculation rules, then run the tool.
Read smallBerryPercentAmongAssessed, assessableBerryCount, unassessedBerryCount. 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
measuredBerryDiametersMm	Measured berry diameters mm	list of number	Required
callerSmallBerryDiameterThresholdMm	Caller small berry diameter threshold mm	number	Required
assessableBerryFlags	Assessable berry flags	list of number	Required

Align nonnegative diameters with binary assessability flags and a positive mm threshold. Require at least one assessed berry. Equality is not small; report assessed and unassessed counts separately.^[1]

Paired lists must be nonempty and have equal lengths.

small percent = 100 × assessed berries with diameter < threshold/assessed berries

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

Output field	Meaning	Value type
smallBerryPercentAmongAssessed	Small berry percent among assessed	number
assessableBerryCount	Assessable berry count	number
unassessedBerryCount	Unassessed berry count	number

Limitations and assumptions

Small diameter alone does not diagnose millerandage or establish grade.

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 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. For a complementary task, use 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.
