Four Factors Composite Score

Combine caller already consistently oriented basketball eFG/turnover/rebound/free-throw scores with explicit weights; no assumed low-turnover sign or canonical universal four-factor composite.

Description

A four-factor composite requires consistently oriented scores.

A four-factor composite requires consistently oriented scores. A lower-is-better turnover metric must be oriented by the caller first.^[1]

The returned values include Caller weighted four factor score. The How section below explains the calculation, input rules and interpretation.

When to use Four Factors Composite Score

Use Four Factors Composite Score when you need to evaluate the supplied records under the calculation and evidence rules below. No canonical universal weighting or automatic turnover sign reversal is supplied.

Prepare the observed race, match or training records and the stated units. Supply independently verified rule editions, calibration tables and targets where requested.

How to use Four Factors Composite Score and understand its results

Prepare the observed race, match or training records and the stated units. Supply independently verified rule editions, calibration tables and targets where requested.
Enter callerOrientedFourFactorScores, callerFourFactorWeights using the field table and calculation rules, then run the tool.
Read callerWeightedFourFactorScore. 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
callerOrientedFourFactorScores	Caller oriented four factor scores	list of number	Required
callerFourFactorWeights	Caller four factor weights	list of number	Required

Enter exactly four score fractions 0–1 and four nonnegative weights with positive total. Normalize weights by scaled sum and return composite.

composite=sum(normalizedWeight×orientedScore)

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

Limitations and assumptions

No canonical universal weighting or automatic turnover sign reversal is supplied.

Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

Use Basketball eFG% Calculator: Effective field-goal percentage gives a made three an extra half made-shot equivalent. It excludes free throws. For a complementary task, use Free Throw Rate Attempted Calculator: Free-throw attempt rate uses FTA/FGA. It is a ratio that can exceed one and differs from made-free-throw conventions.
