Tonewood Moisture Risk with moisture defect severity of 15 score: a worked example

Push moisture defect severity up to 15 score and the picture changes. This example computes every intermediate figure at that operating point. Use during incoming inspection when comparing moisture risk across spruce tops, maple billets, mahogany neck blanks, and other tonewood lots queued for production.

The inputs for this scenario

  • Moisture defect severity: 15 score (raised for this scenario; the documented default is 6)
  • Moisture occurrence likelihood: 4 score (unchanged)
  • Moisture detection ability: 3 score (unchanged)

Working through the calculation

  • Applying the documented formula (Tonewood moisture risk score = moisture defect severity × moisture occurrence likelihood × moisture detection ability) to the inputs above produces each figure below.
  • At this operating point the engine returns 8.15 score for tonewood moisture risk score, the number this scenario is built around.
  • At this operating point the engine returns 15 score for moisture defect severity.
  • At this operating point the engine returns 4 score for moisture occurrence likelihood.
  • At this operating point the engine returns 3 score for moisture detection ability.

How this compares with the baseline

  • Against the tool's baseline example, where moisture defect severity sits at 6 score and the headline result is 4.55 score, this scenario comes in 79.12% above the baseline at 8.15 score.
  • It multiplies severity, occurrence, and detection scores into a single risk priority number for a tonewood lot so lots can be ranked and triaged. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Tonewood moisture risk score: 8.15 score (headline result)
  • Moisture defect severity: 15 score
  • Moisture occurrence likelihood: 4 score
  • Moisture detection ability: 3 score
