Understanding the 100-point index

The index converts the published five-point rating using a fixed scale. It preserves order and ties; it is neither a new performance measurement nor a quality percentage.

85100Excellent
7084Very strong
5569Good
4054Notable trade-offs

For example: 3.0/5 → 36; 4.0/5 → 64; 4.5/5 → 81; 5.0/5 → 100.

Index = 100 × (rating out of 5 ÷ 5)², rounded to the nearest integer.

Equal original ratings keep an equal index. Adding models does not change the scale.

Comparison guidelines

0 points: equal index. 1–7: small gap. 8–14: visible advantage. 15 or more: large gap. These are editorial guidelines, not statistical significance thresholds.

Indices derived from external reviews retain their original rating and source. Methods and dates may differ, so these comparisons do not declare an automatic winner.

The generation that brought Wear OS to Samsung watches. A used option to consider for wrist-based apps, with limited battery life and Android-only compatibility.
