Checks that a finding survives its own arithmetic before it becomes a sentence, using weighted averages instead of averages of averages, catching comparisons that reverse when groups are pooled, keeping unlabelled buckets out of rankings, and requiring a stated base behind every percentage. Use when writing takeaways or a summary, when naming the top or best performing segment, channel or period, when reporting growth or a decline as a percentage, or when saying that something drove or caused a change.
