Batch Potency Variance at 5.76% lowest potency lab result: a worked example

Suppose lowest potency lab result falls to 5.76%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate potency spread across compliant lab results or retained samples so quality and production teams can understand batch uniformity before release decisions.

The inputs for this scenario

  • Lowest potency lab result: 5.76 % (the input this scenario stresses; the baseline uses 8)
  • Highest potency lab result: 12 % (held at the documented default)
  • Average or target potency: 10 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Potency spread = highest potency result - lowest potency result.
  • Potency variance works out to 62.4 % at these inputs, and this is the headline figure for the scenario.
  • Potency spread works out to 6.24 value at these inputs.
  • Lowest potency result works out to 5.76 value at these inputs.
  • Highest potency result works out to 12 value at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where lowest potency lab result sits at 8% and the headline result is 40 %, this scenario comes in 56% above the baseline at 62.4 %.
  • It computes potency variance as the spread between the highest and lowest results divided by the average or target potency, shown as a percentage. 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

  • Potency variance: 62.4 % (headline result)
  • Potency spread: 6.24 value
  • Lowest potency result: 5.76 value
