Huile lavante 2 in 1

We don't rate products ourselves. We collect what each public rater already says, put every scale on common ground, and keep the disagreements visible instead of averaging them away.

1. 1

   Collect each rater's own score

   Every source keeps its native verdict for this product. We never invent a score for an axis a source didn't measure.

2. 2

   Normalize to 0–100, higher = better

   Raters can use different scales and directions: some where a low number means safe, some where a high one does. We map them all onto one 0–100 axis and flip the ones that run backwards so the numbers are finally comparable.

3. 3

   Average per axis, but keep the spread
