Wilks Coefficient Calculator
Evaluate caller verified Wilks fifth-degree edition/cohort denominator (six constant-first coefficients, numerator 500) on actual meet total; example original men's coefficients, category never inferred, not DOTS fourth-degree or simple allometric normalization.
Description
Wilks normalizes a lifting total using a body-mass polynomial tied to a verified edition and cohort.
Wilks normalizes a lifting total using a body-mass polynomial tied to a verified edition and cohort. Coefficients and applicability must be supplied explicitly.1
The returned values include Caller edition denominator, Caller edition strength score. The How section below explains the calculation, input rules and interpretation.
When to use Wilks Coefficient Calculator
Use Wilks Coefficient Calculator when you need to evaluate the supplied records under the calculation and evidence rules below. No cohort, mass cap or edition is inferred; the example coefficients do not establish current competition rules.
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 Wilks Coefficient Calculator 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 observedBodyMassKg, observedMeetTotalKg, callerVerifiedConstantFirstDenominatorCoefficients, callerVerifiedScoreNumerator, callerCoefficientEditionId using the field table and calculation rules, then run the tool.
- Read callerEditionDenominator, callerEditionStrengthScore. 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 |
|---|---|---|---|
| observedBodyMassKg | Observed body mass kg | number | Required |
| observedMeetTotalKg | Observed meet total kg | number | Required |
| callerVerifiedConstantFirstDenominatorCoefficients | Caller verified constant first denominator coefficients | list of number | Required |
| callerVerifiedScoreNumerator | Caller verified score numerator | number | Required |
| callerCoefficientEditionId | Caller coefficient edition id | string | Required |
Enter positive body mass, nonnegative meet total, exactly six finite constant-first fifth-degree coefficients, numerator exactly 500 and a nonblank edition label≤128 characters. Evaluate by Horner’s method and require positive finite denominator. Return denominator and score.
denominator=sum(coeff[i]×mass^i); score=500×total/denominator Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| callerEditionDenominator | Caller edition denominator | number |
| callerEditionStrengthScore | Caller edition strength score | number |

}Limitations and assumptions
No cohort, mass cap or edition is inferred; the example coefficients do not establish current competition rules.
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. Extremely large text inputs are rejected. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use DOTS Score Powerlifting Calculator: DOTS uses a fourth-degree body-mass denominator tied to a verified edition and cohort. It differs from Wilks’ fifth-degree form. For a complementary task, use Sinclair Coefficient Weightlifting Calculator: Sinclair adjusts a weightlifting total using cycle-specific constants. At or above the reference body mass the coefficient is one.
