Lot Genealogy Completeness at 22% record completeness gap: a worked example

Suppose record completeness gap falls to 22%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimates the cost of closing gaps in lot genealogy so every lot has complete forward and backward traceability.

The inputs for this scenario

  • Production lots to reconstruct: 300 lots (held at the documented default)
  • Cost per lot reconstruction: 40 $/lot (held at the documented default)
  • Record completeness gap: 22 % (the input this scenario stresses; the baseline uses 30)
  • System and audit adder: 2,500 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Genealogy gap cost = lots x cost per lot x completeness gap% + system adder.
  • Total lot genealogy completeness cost works out to 5,140 $ at these inputs, and this is the headline figure for the scenario.
  • Lot genealogy completeness cost per unit works out to 17.13 $ / piece at these inputs.
  • Variable lot genealogy completeness cost works out to 2,640 $ at these inputs.
  • Fixed lot genealogy completeness adder works out to 2,500 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where record completeness gap sits at 30% and the headline result is 6,100 $, this scenario comes in 15.74% below the baseline at 5,140 $.
  • It computes the total reconstruction cost as lots × per-lot cost × completeness gap, plus a fixed system and audit adder, and the resulting cost per lot. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
