Parfum Glade Johnson fraicheur muguet

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
