OCRA Recovery Period Factor Lookup

OCRA recovery factor exact caller independently verified recovery-spacing/duration/task-time reference; no factor from total rest minutes alone. Exact caller verified numeric reference; signed deviations retained. Caller independently establishes matching units, evidence, method edition and applicability; output is not compliance, diagnosis, work-safety approval, geological identity or validated hazard prediction.

Description

An OCRA recovery factor depends on a documented assessment context and reference entry.

An OCRA recovery factor depends on a documented assessment context and reference entry.^[1]

Exact retrieval of a caller value does not assess an entire repetitive-work task. Use this tool to compare an observation with an exact caller-supplied numeric reference.

When to use OCRA Recovery Period Factor Lookup

Use this tool to compare an observation with an exact caller-supplied numeric reference. Establish the observation protocol, units, task and reference population or review criterion before entering measurements.

How to use OCRA Recovery Period Factor Lookup and understand its results

Establish the observation protocol, units, task and reference population or review criterion before entering measurements.
Enter callerVerifiedOcraRecoveryScheduleKeys, callerVerifiedOcraRecoveryScheduleValues, queryOcraRecoveryScheduleKey, observedOcraRecoveryScheduleValue, using the field meanings and rules below, then run the tool.
Read callerReferenceValue, signedObservedMinusReference. Interpret the fields using their units, signs and evidence conventions below.
If input validation fails, correct the reported field and run again. Before applying the result, check reference scope, model assumptions and any missing evidence or placeholder values.

Input field	Meaning	Value type	Requirement
callerVerifiedOcraRecoveryScheduleKeys	Caller verified ocra recovery schedule keys; caller assertion or measurement requiring independent evidence	list of string	Required
callerVerifiedOcraRecoveryScheduleValues	Caller verified ocra recovery schedule values; caller assertion or measurement requiring independent evidence	list of number	Required
queryOcraRecoveryScheduleKey	Query ocra recovery schedule key	string	Required
observedOcraRecoveryScheduleValue	Observed ocra recovery schedule value	number	Required

Enter nonempty aligned caller reference IDs and numeric reference values, an exact query ID and an observed value on the same unit and protocol basis. Reference values and the observation are finite signed numbers; there is no nonnegative check here and they need not be integers. IDs must be unique and nonblank, with at most 128 UTF-16 units each. The implementation uses case-sensitive exact matching without trimming, returns the matched reference value and subtracts it from the observation. An absent query or duplicate key fails. No regional dataset is installed, retrieved or authenticated.

reference=values[indexOfExact(queryId,ids)]; signedDifference=observed−reference

Use the exact units, boundary rules, ordering and missing-evidence conventions above.

Output field	Meaning	Value type
callerReferenceValue	Caller Reference Value; follow the units, sign, ordering and evidence convention stated above	number
signedObservedMinusReference	Signed Observed Minus Reference; follow the units, sign, ordering and evidence convention stated above	number

Limitations and assumptions

The numerical reference, unit basis and observation come from the caller. No authoritative regional table, standard edition, calibration or management rule is installed, retrieved or verified.

All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse evidence arrays fail validation; the specific bounds and alignment requirements are stated above. Extremely large inputs or outputs can also be rejected. An input error is distinct from a successful result reporting false, no matches or missing evidence.
