Moisture Target Window at 140% max allowable exit moisture: a worked example
Push max allowable exit moisture up to 140% and the picture changes. This example computes every intermediate figure at that operating point. Use it during dryer setup or after a recipe change to confirm the exit moisture is within the acceptable window before releasing boards to the stacker.
The inputs for this scenario
- Max allowable exit moisture: 140 % (raised for this scenario; the documented default is 125)
- Measured exit moisture: 100 % (unchanged)
- Design reference moisture: 100 % (unchanged)
Working through the calculation
- Applying the documented formula (Moisture headroom = max allowable exit moisture - measured exit moisture) to the inputs above produces each figure below.
- At this operating point the engine returns 40 % for margin, the number this scenario is built around.
- At this operating point the engine returns 40 value for absolute margin.
- At this operating point the engine returns 140 value for available amount.
- At this operating point the engine returns 100 value for required amount.
How this compares with the baseline
- Against the tool's baseline example, where max allowable exit moisture sits at 125% and the headline result is 25 %, this scenario comes in 60% above the baseline at 40 %.
- It computes the moisture headroom between your allowable ceiling and measured exit moisture, then expresses that headroom as a margin against a design reference moisture. 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.

- Margin: 40 % (headline result)
- Absolute margin: 40 value
- Available amount: 140 value
- Required amount: 100 value
