Pipe Cut Yield at 69% target pipe cut yield: a worked example

This worked example runs the pipe cut yield numbers for a tougher week than the baseline: 69% target pipe cut yield instead of the typical 96%. Calculate sprinkler pipe cut yield from accepted cut pipe pieces versus pipe cuts started and compare it with the target.

The inputs for this scenario

  • Accepted sprinkler pipe cuts: 238 pipe sections (held at the documented default)
  • Total sprinkler pipe cuts started: 250 pipe sections (held at the documented default)
  • Target pipe cut yield: 69 % (the input this scenario stresses; the baseline uses 96)

Working through the calculation

  • The calculation starts from the formula this tool documents: Pipe Cut Yield = accepted sprinkler pipe cuts รท total sprinkler pipe cuts started.
  • Pipe Cut Yield works out to 95.2 % at these inputs, and this is the headline figure for the scenario.
  • Gap to pipe cut yield target works out to -26.2 points at these inputs.
  • Accepted sprinkler pipe cuts works out to 238 pipe sections at these inputs.
  • Total sprinkler pipe cuts started works out to 250 pipe sections at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target pipe cut yield sits at 96% and the headline result is 95.2 %, this scenario lands almost exactly on the baseline at 95.2 %.
  • Use it at the end of a saw or groover shift, when qualifying a new operator or blade, or when reconciling spool-drawing footage against actual usable cut sections. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Pipe Cut Yield: 95.2 % (headline result)
  • Gap to pipe cut yield target: -26.2 points
  • Accepted sprinkler pipe cuts: 238 pipe sections
  • Total sprinkler pipe cuts started: 250 pipe sections
