How We Score — Methodology & Sources
No black box. Here is exactly how this verdict was produced.
1. Data sources
Every price, rating, review count, seller, availability and specification is read directly from the live listing on Amazon and Amazon, then cached and re-verified on refresh. Where a marketplace does not publish a figure we label it unstated rather than estimating it.
2. Category detection
This pair was classified as Default. The category decides which specs matter and how the five dimensions are weighted.
3. Spec-by-spec verdicts
Where both listings publish the same attribute in a measurable unit we normalise units (g/kg, GB/TB, inch/cm, W/kW, hours/minutes) and compare. A difference under 4 normalised points counts as a tie so rounding noise never decides a winner.
4. Dimension weights for Default
- Value 22%
- Performance 22%
- Build / Quality 18%
- Sentiment 20%
- Trust 18%
5. Bayesian rating adjustment
Raw star averages reward tiny samples. We shrink each rating toward the marketplace mean (4.50/5) using a prior of 40 votes, so 678 and 276 ratings are compared fairly.
6. Confidence & independence
Data confidence: 0.69 for A and 0.65 for B. Scores are computed deterministically from the data above and are never influenced by affiliate commission rates.
