Head Trained Vine Arm Count

Audit observed head-trained vine permanent arms against caller per-vine targets, keeping simultaneous local deficits/excesses rather than hiding them in pooled count; no training/pruning recommendation.

Description

Permanent-arm inventory can contain local deficits and excesses at the same time.

Permanent-arm inventory can contain local deficits and excesses at the same time. A pooled total can hide those differences.

When to use Head Trained Vine Arm Count

Use this tool to audit observed head-trained vine permanent arms against caller per-vine targets, keeping simultaneous local deficits/excesses rather than hiding them in pooled count; no training/pruning recommendation.

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 Head Trained Vine Arm 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 observedRetainedArmCounts, callerTargetArmCounts using the field table and calculation rules, then run the tool.
Read armCountDeficits, armCountExcesses, totalObservedRetainedArms. 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
observedRetainedArmCounts	Observed retained arm counts	list of number	Required
callerTargetArmCounts	Caller target arm counts	list of number	Required

Align nonnegative integer observed and target arm counts. Return both local arrays and the safely countable observed total.^[1]

Paired lists must be nonempty and have equal lengths.

deficit = max(0,target − observed); excess = max(0,observed − target)

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

Output field	Meaning	Value type
armCountDeficits	Arm count deficits	list of number
armCountExcesses	Arm count excesses	list of number
totalObservedRetainedArms	Total observed retained arms	number

Limitations and assumptions

Caller targets are not training or pruning recommendations.

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 Guyot Cane Total Buds: Account measured multi-cane Guyot retained fruit buds and separate renewal-spur buds by vine; no conflation of renewal with crop buds or prediction of fruitfulness. For a complementary task, use Shoot Thinning Percent Removal: Audit matched shoot removal across unequal represented vine cohorts with correct inventory weighting, not averaging percentages or a pruning prescription.
