Gauge Recall Rate at 68% target recall rate: a worked example

Suppose target recall rate falls to 68%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate the percentage of gauges successfully recalled or presented for calibration during a recall period so gauge control can spot missed assets before they become overdue.

The inputs for this scenario

Gauges recalled on time: 8 gauges (held at the documented default)
Total gauges due for recall: 250 gauges (held at the documented default)
Target recall rate: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

The calculation starts from the formula this tool documents: Gauge recall rate = gauges recalled on time ÷ total gauges due × 100.
Gauge recall rate works out to 3.2 % at these inputs, and this is the headline figure for the scenario.
Recall gap to target works out to 64.8 points at these inputs.
Gauges recalled on time works out to 8 count at these inputs.
Total gauges due works out to 250 count at these inputs.

How this compares with the baseline

Against the tool's baseline example, where target recall rate sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
It computes the percentage of due gauges that were recalled on time and the point gap between that rate and 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.
