Delta above the unaffected dry standard, a dry/wet verdict, and points still to remove from moisture-meter readings.
Example
You enter
- Unaffected reference reading (dry standard) 12
- Affected material reading 35
- Acceptable delta above standard 4
You get
- Delta above standard 23
- Points still to remove 19
Details, formula, and sources
delta = affected_reading - reference_reading (the unaffected dry standard); at_dry_standard = delta <= acceptable_delta; points_to_go = max(0, delta - acceptable_delta).
