Labeling Workload at 32% label qa and rework allowance: a worked example

Push label qa and rework allowance up to 32% and the picture changes. This example computes every intermediate figure at that operating point. Use it when computer vision, anomaly detection, or quality analytics teams need to plan human labeling effort.

The inputs for this scenario

  • Samples requiring labels: 4,800 samples (unchanged)
  • Labeling completion rate: 6 samples / min (unchanged)
  • Label QA and rework allowance: 32 % (raised for this scenario; the documented default is 28)

Working through the calculation

  • Applying the documented formula (Base labeling time = samples requiring labels รท labeling completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,056 min for required labeling time, the number this scenario is built around.
  • At this operating point the engine returns 800 min for base labeling time.
  • At this operating point the engine returns 32 % for label qa and rework allowance.
  • At this operating point the engine returns 6 pieces / min for labeling completion rate.

How this compares with the baseline

  • Against the tool's baseline example, where label qa and rework allowance sits at 28% and the headline result is 1,024 min, this scenario comes in 3.13% above the baseline at 1,056 min.
  • It converts a sample count and labeling rate into required annotation minutes, including a QA and rework allowance. 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

  • Required labeling time: 1,056 min (headline result)
  • Base labeling time: 800 min
  • Label QA and rework allowance: 32 %
  • Labeling completion rate: 6 pieces / min
