Description
Weighted area=gross-edge+edge*factor; excluded equivalent=edge*(1-factor).
Extension-training comparisons depend on score ranges, credit weights, unit factors, plot support and cost bases. A normalized difference or area-scaled harvest describes supplied records rather than proving learning, causal adoption or an agronomic effect. Caller-chosen factors need separate justification.
Weighted area=gross-edge+edge*factor; excluded equivalent=edge*(1-factor).
When to use this tool
Use Demonstration Plot Edge Area Factor when checking the stated training, credit, demonstration-plot, unit or cost convention.
How to use the tool and how it works
- Enter grossArea, edgeArea, suppliedEdgeFactor. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read weightedArea, excludedEquivalent. Use the output convention below.
Require nonnegative gross area, edge area within gross and edge factor in [0,1]. Weighted area=gross-edge+edge*factor; excluded equivalent=edge*(1-factor).1

| weightedArea | Weighted Area | Required. Finite number. |
| excludedEquivalent | Excluded Equivalent | Required. Finite number. |

}Limitations and assumptions
- The edge factor is an assumed weight rather than a measured yield correction or an inferred edge-effect model.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use verified representative observations and appropriate complete educational, statistical or budget analysis for substantive training, agricultural or funding decisions.
