Line Rate at 62% expected line efficiency: a worked example

Suppose expected line efficiency falls to 62%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate effective units per hour from parallel lanes or stations, standard rate, and expected line efficiency.

The inputs for this scenario

  • Active producing lanes or stations: 3 lanes (held at the documented default)
  • Standard output per lane-hour: 420 units / lane-hr (held at the documented default)
  • Expected line efficiency: 62 % (the input this scenario stresses; the baseline uses 86)

Working through the calculation

  • The calculation starts from the formula this tool documents: Theoretical line rate = active lanes × standard output per lane-hour.
  • Effective line rate works out to 781 units / hr at these inputs, and this is the headline figure for the scenario.
  • Theoretical line rate works out to 1,260 units / hr at these inputs.
  • Rate lost to inefficiency works out to 479 units / hr at these inputs.
  • Line efficiency works out to 62 % at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where expected line efficiency sits at 86% and the headline result is 1,084 units / hr, this scenario comes in 27.91% below the baseline at 781 units / hr.
  • It computes the effective output in units per hour by multiplying active lanes by standard per-lane output, then derating for line efficiency. 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

  • Effective line rate: 781 units / hr (headline result)
  • Theoretical line rate: 1,260 units / hr
  • Rate lost to inefficiency: 479 units / hr
  • Line efficiency: 62 %
