Final Tuning Capacity at 99% tuning room uptime: a worked example

What does the result look like when tuning room uptime reaches 99%? The full calculation is worked below with real intermediate numbers. Use when the tuning room is being asked to take on more volume and you need to know whether the actual good-output capacity covers demand.

The inputs for this scenario

  • Instruments per tuning cycle: 4 instruments / cycle (unchanged)
  • Tuning cycles available: 480 cycles (unchanged)
  • Tuning room uptime: 99 % (raised for this scenario; the documented default is 90)
  • First-pass tuning yield: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross tuning capacity = instruments per tuning cycle × tuning cycles available) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,844 units for good tuning capacity, the number this scenario is built around.
  • At this operating point the engine returns 1,920 units for gross tuning capacity.
  • At this operating point the engine returns 19.2 units for tuning room downtime loss.
  • At this operating point the engine returns 57.02 units for first-pass tuning yield loss.

How this compares with the baseline

  • Against the tool's baseline example, where tuning room uptime sits at 90% and the headline result is 1,676 units, this scenario comes in 10% above the baseline at 1,844 units.
  • A figure at this level is achievable when tuning room uptime is genuinely sustained, not just peaked for a shift. It assumes uptime and first-pass yield are stable averages; a tricky batch, a humidity swing, or a tuner absence can pull actual good capacity well below the calculated figure.

Results at a glance

  • Good tuning capacity: 1,844 units (headline result)
  • Gross tuning capacity: 1,920 units
  • Tuning room downtime loss: 19.2 units
  • First-pass tuning yield loss: 57.02 units
