Seed Trial Observation Gap Tool

Description

Return matched seed-observation visits and mean timing gap.

Plant observations and seed or growth summaries depend on sampling area, observation time, material basis and inclusion policy. A local count or ratio can be consistent with the supplied records without estimating a complete population, establishing germination quality or identifying a growth mechanism.

Return matched seed-observation visits and mean timing gap.

When to use this tool

Use Seed Trial Observation Gap when checking the stated botanical observation, seed, growth or coverage convention.

How to use the tool and how it works

Enter scheduledTimes, observedTimes, matched. Follow any array-alignment requirements below. Use the units and conventions below.
Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
Read matchedVisits, missedVisits, meanTimingGap, defined. Inspect defined before interpreting the associated values.

Return matched seed-observation visits and mean timing gap. Require aligned scheduled/observed/matched arrays; count matched/unmatched, meanTimingGap averages observed-scheduled only where matched, otherwise zero with defined false.^[1]

Input field	Meaning and units	Accepted input
scheduledTimes	Scheduled Times	Required. Array of finite number; maximum items 256.
observedTimes	Observed Times	Required. Array of finite number; maximum items 256.
matched	Matched	Required. Array of boolean; maximum items 256.

Output field	Interpretation	Returned shape
matchedVisits	Matched Visits	Required. Safe integer.
missedVisits	Missed Visits	Required. Safe integer.
meanTimingGap	Mean Timing Gap	Required. Finite number.
defined	Reporting flag under the explicit denominator or information policy above; inspect any zero placeholder or policy-defined value.	Required. Boolean.

Limitations and assumptions

Matched flags and clock bases are supplied; no visit identity, germination timing or experiment quality is verified.
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

Use verified observations and an appropriate sampling, growth or material-balance model; assess uncertainty and biological meaning separately.
