Minimum Duration of a Deviation from the Valence Rule to Detect a
Discrepancy Error
A discrepancy error can be detected as soon as the deviation from the valence
rule is greater than the value determined in section "Maximum Duration of a
Deviation from the Valence Rule to Avoid Unwanted Discrepancy Errors."
However, detection of a discrepancy error is only ensured if the deviation of the
input values from the valence rule lasts longer than the value determined by the
following formula.
