Pheromone Monitoring Lure Age Gap Tool

Description

age = inspectionDay-deploymentDay; remaining = replacementInterval-age; replacementDue = age >= replacementInterval.

Lure-age and servicing records need a common day origin and an explicit installation or replacement anchor. An age or due flag describes the supplied schedule, not measured lure effectiveness.

age = inspectionDay-deploymentDay; remaining = replacementInterval-age; replacementDue = age >= replacementInterval.

When to use this tool

Use Pheromone Monitoring Lure Age Gap when checking a recorded lure age or caller-supplied servicing interval.

How to use the tool and how it works

Enter inspectionDay, deploymentDay, replacementInterval. Use the units and conventions below.
Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
Read age, remaining, replacementDue. Inspect replacementDue before interpreting the associated values.

Require inspectionDay >= deploymentDay and positive replacementInterval. age = inspectionDay-deploymentDay; remaining = replacementInterval-age; replacementDue = age >= replacementInterval.^[1]

Input field	Meaning and units	Accepted input
inspectionDay	Inspection Day	Required. Finite number.
deploymentDay	Deployment Day	Required. Finite number.
replacementInterval	Replacement Interval	Required. Finite number; strictly above 0.

Output field	Interpretation	Returned shape
age	Age	Required. Finite number.
remaining	Remaining	Required. Finite number.
replacementDue	True at or beyond the supplied replacement interval, including equality.	Required. Boolean.

Limitations and assumptions

Use matching day coordinates and interval units. Equality is due and overdue remaining values are negative; the supplied interval is not a recommended lure replacement standard.
Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.

Alternative or Complementary methods

Review deployment histories and product-specific monitoring protocols before selecting a replacement schedule.
