Numeric threshold without a rounding rule
PMI-WP-007NoteTrack: Measurement & calibrationRevised
Definition
Written to be quoted. This is the sentence to cite when a counterparty disagrees, not the sentence the tool shows you.
A numeric comparison is stated without the precision and rounding convention needed to evaluate it identically twice. “More than 5%” resolves differently at 5.004% depending on where the reader rounds.
Remedy
State the measurement source, its precision, and the rounding rule.
Severity
Note — worth confirming
Where it comes from
How would we know if these prices were good?
Scoring rules, calibration measurement, sample-size thresholds and comparison methods — so that claims about forecast quality can be audited rather than asserted.
