Cannabis, Hemp & Controlled Agriculture Processing worked example
Batch Potency Variance at 9.2% lowest potency lab result: a worked example
What does the result look like when lowest potency lab result reaches 9.2%? The full calculation is worked below with real intermediate numbers. Use it when batch potency variance in cannabis, hemp and controlled agriculture processing is being audited or compared against a control chart.
The inputs for this scenario
- Lowest potency lab result: 9.2 % (raised for this scenario; the documented default is 8)
- Highest potency lab result: 12 % (unchanged)
- Average or target potency: 10 % (unchanged)
Working through the calculation
- Applying the documented formula (Potency spread = highest potency result - lowest potency result) to the inputs above produces each figure below.
- At this operating point the engine returns 28 % for potency variance, the number this scenario is built around.
- At this operating point the engine returns 2.8 value for potency spread.
- At this operating point the engine returns 9.2 value for lowest potency result.
- At this operating point the engine returns 12 value for highest potency result.
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 30% below the baseline at 28 %.
- A figure at this level is achievable when lowest potency lab result is genuinely sustained, not just peaked for a shift. With only min, max and average it ignores sample size and distribution shape, so two batches with the same spread but different consistency between extremes look identical.
Results at a glance
- Potency variance: 28 % (headline result)
- Potency spread: 2.8 value
- Lowest potency result: 9.2 value
- Highest potency result: 12 value
