Cupping Sample Rate at 54% target cupping sample rate: a worked example

Suppose target cupping sample rate falls to 54%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate cupping sample rate from cupped lots or batches, total lots or batches, and target sampling rate.

The inputs for this scenario

  • Lots cupped or sensory-reviewed: 36 units (held at the documented default)
  • Total lots or batches in scope: 48 units (held at the documented default)
  • Target cupping sample rate: 54 % (the input this scenario stresses; the baseline uses 75)

Working through the calculation

  • The calculation starts from the formula this tool documents: Cupping Sample Rate = cupped or sensory-reviewed lots ÷ total lots or batches in scope × 100.
  • cupping sample rate works out to 75 % at these inputs, and this is the headline figure for the scenario.
  • cupping sample rate gap to target works out to -21 points at these inputs.
  • cupped or sensory-reviewed lots works out to 36 count at these inputs.
  • total lots or batches in scope works out to 48 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target cupping sample rate sits at 75% and the headline result is 75 %, this scenario lands almost exactly on the baseline at 75 %.
  • It divides cupped lots by total lots in scope and multiplies by 100 to give your sensory coverage rate, then compares it against your target to show the gap. 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.

Results at a glance

  • cupping sample rate: 75 % (headline result)
  • cupping sample rate gap to target: -21 points
  • cupped or sensory-reviewed lots: 36 count
  • total lots or batches in scope: 48 count
