How we score

Scorata scores summarize analyzed review evidence on a 1–5 scale; they are not laboratory measurements or a simple average of customer star ratings. Feature scores summarize the reviews covering that feature. The overall score averages feature scores within each review, then combines review averages. When both expert and customer evidence are available, those two groups receive equal weight. Products can have different review coverage, so small score gaps do not establish a winner.

Recommendations prioritize important features for the category, with a score of at least 3.5, a gap of at least 0.25 points and at least two supporting reviews per product. Features with widely varying scores or broad connectivity contexts are excluded from recommendations. These safeguards do not establish statistical significance.
