Rebelay Length Optimization Calculator

independently approved rebelay rope-segment/allowance inventory; no automatically optimized anchor design. Same meters; actual knots/end tails, load, fixed rigging and usable length independently assessed. No rope selection, round-up, safe-rigging approval or universally sufficient length.

Description

A rebelay rope inventory lists approved segments and separate allowances.

A rebelay rope inventory lists approved segments and separate allowances.^[1]

Adding those records does not optimize anchor positions or design a new rigging arrangement.

When to use Rebelay Length Optimization Calculator

Use this tool to obtain conditionalInventoryRopeLengthMeters from the supplied records using the stated calculation. Establish the survey or observation scope, reference frame, units and independently applicable calibration or qualified plan.

How to use Rebelay Length Optimization Calculator and understand its results

Establish the survey or observation scope, reference frame, units and independently applicable calibration or qualified plan.
Enter actualApprovedRebelaySegmentsMeters, callerIndependentAllowanceLengthsMeters, using the field meanings and rules below, then run the tool.
Read result.conditionalInventoryRopeLengthMeters. Use the units and sign conventions below, and review any unknown records separately.
Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.

Input field	Meaning	Value type	Requirement
actualApprovedRebelaySegmentsMeters	Actual approved rebelay segments meters	list of number	Required
callerIndependentAllowanceLengthsMeters	Caller independent allowance lengths meters	list of number	Required

Supply two nonempty lists of nonnegative path-segment and allowance lengths in metres. Add their totals; lists may have different lengths because they are separate inventories. The implementation does not choose allowances, round to available rope lengths or optimize a route.

inventoryRopeLengthMeters=ΣsegmentLengths+ΣallowanceLengths

Use the matching field units and the exact boundary, ordering and reference rules above.

Output field	Meaning	Value type
result	Qualified observed calculation or explicit reference	object
result.conditionalInventoryRopeLengthMeters	Sum of recorded path segments and separate allowances in metres.	number

Limitations and assumptions

The actual observation coverage, calibration and qualified plan determine applicability. A numerical result does not establish survey accuracy, route suitability, atmosphere conditions or equipment adequacy beyond the declared comparison.

Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Lists and matrices must be dense, without missing cells. Numeric lists allow at most 10000 entries, subject to the narrower lengths and code rules above. Extremely large composite outputs are rejected.
