Seam Check Rate at 72% target seam-check completion rate: a worked example

Suppose target seam-check completion rate falls to 72%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Track completion of required can seam checks, teardowns, or vision inspections during a canning run.

The inputs for this scenario

  • Completed double-seam checks or teardowns: 92 units (held at the documented default)
  • Required seam checks for the run: 96 units (held at the documented default)
  • Target seam-check completion rate: 72 % (the input this scenario stresses; the baseline uses 100)

Working through the calculation

  • The calculation starts from the formula this tool documents: Seam check completion rate = completed double-seam checks or teardowns ÷ required seam checks for the run × 100.
  • Seam check completion rate works out to 95.83 % seam checks at these inputs, and this is the headline figure for the scenario.
  • Seam check completion rate gap to target works out to -23.83 points at these inputs.
  • Completed double-seam checks or teardowns works out to 92 count at these inputs.
  • Required seam checks for the run works out to 96 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target seam-check completion rate sits at 100% and the headline result is 95.83 % seam checks, this scenario lands almost exactly on the baseline at 95.83 % seam checks.
  • It divides completed double-seam checks or teardowns by the required number for the run and multiplies by 100, then reports the gap to your target. 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.

Results at a glance

  • Seam check completion rate: 95.83 % seam checks (headline result)
  • Seam check completion rate gap to target: -23.83 points
  • Completed double-seam checks or teardowns: 92 count
  • Required seam checks for the run: 96 count
