The total area of the pavement section being inspected.
Simulations
Set to 1 for a single deterministic calculation. Increase for Monte Carlo analysis.
Distress Data
Instructions:
Enter Quantity and select Unit for each distress found.
Std Dev models measurement uncertainty. You can enter a fixed value OR use the "Model" button to set parameters A and B for the formula: StdDev = A * (Quantity ^ B). Note: A & B are assumed to be Imperial (SqFt) based. If metric is selected, conversion is applied automatically.
Apply ASTM Accuracy (10%/20%)
- Sets Std Dev based on measurement type (Linear: 10%, Area: 20%) per ASTM D6433 Section 8.1.

Calculation Trace (Max CDV Iteration):
Shows step-by-step logic for determining Max CDV per ASTM D6433. The algorithm iteratively reduces the smallest deduct value to 2.0 until q=1.
