Cylinder Loss Reserve at 3.45% target cylinder loss reserve rate: a worked example

Push target cylinder loss reserve rate up to 3.45% and the picture changes. This example computes every intermediate figure at that operating point. Use it when estimating reserve for lost cylinders, customer-held assets, unreturned cylinders, damaged cylinders, or write-offs.

The inputs for this scenario

  • Missing or written-off cylinders: 38 cylinders (unchanged)
  • Total cylinders at risk: 1,200 cylinders (unchanged)
  • Target cylinder loss reserve rate: 3.45 % (raised for this scenario; the documented default is 3)

Working through the calculation

  • Applying the documented formula (Cylinder loss reserve rate = missing or written-off cylinders ÷ total cylinders at risk × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 3.17 % for cylinder loss reserve rate, the number this scenario is built around.
  • At this operating point the engine returns 0.28 points for cylinder loss reserve gap to target.
  • At this operating point the engine returns 38 count for missing or written-off cylinders.
  • At this operating point the engine returns 1,200 count for total cylinders at risk.

How this compares with the baseline

  • Against the tool's baseline example, where target cylinder loss reserve rate sits at 3% and the headline result is 3.17 %, this scenario lands almost exactly on the baseline at 3.17 %.
  • It computes the cylinder loss reserve rate as missing or written-off cylinders divided by the total fleet at risk, and the gap in points between that rate and your target. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Cylinder loss reserve rate: 3.17 % (headline result)
  • Cylinder loss reserve gap to target: 0.28 points
  • Missing or written-off cylinders: 38 count
  • Total cylinders at risk: 1,200 count
