The estimate uses the lowest sufficiently sampled credible-reviewer cohort and never raises the displayed average. Manipulation risk does not subtract stars directly.
Why this boost score?
Campaign-like months contribute to the risk verdict, while the rating remains based only on observed credible-reviewer evidence. Elevated risk begins at 35/100.
