How scoring works
The formula behind the points for each position on your chart
The formula
Each position on your personal chart is worth a number of points for the Global 100. 1st position always scores 1,000 points. From there, each following position scores 95% of the points of the position above it, not a fixed amount less, but a percentage of the position above. This forms a geometric curve: points drop fast near the top of the chart and increasingly slower as the position advances.
As a formula: points for position N = 1,000 × 0.95 raised to (N − 1), rounded to the nearest whole number. This calculation applies to all 100 possible positions on a chart.
Position-to-points table
Some reference points on the curve, from 1st to 100th position:
| Position | Points |
|---|---|
| 1ª | 1,000 |
| 2ª | 950 |
| 3ª | 903 |
| 4ª | 857 |
| 5ª | 815 |
| 10ª | 630 |
| 15ª | 488 |
| 20ª | 377 |
| 30ª | 226 |
| 50ª | 81 |
| 75ª | 22 |
| 100ª | 6 |
Practical examples
If a song appears in 1st position on 3 different charts in the same week, it adds up 3 × 1,000 = 3,000 points to that week's Global 100.
If a song appears in 1st position on one chart and 10th position on another chart, in the same week, it adds up 1,000 + 630 = 1,630 points.
A song that appears only in 50th position on a single chart, on the other hand, adds up just 81 points from that chart, far less than a song that appears just once in 1st position on any chart.
Why this curve
The geometric curve was chosen on purpose: it rewards conviction (being ranked highly) more than volume (appearing on many charts in low positions). A song in 1st position on 5 different charts adds up 5 × 1,000 = 5,000 points.
For a song in 20th position (377 points per chart) to reach that same total, it would need to appear on at least 14 different charts (14 × 377 = 5,278). This design is what makes the Global 100 value someone who puts a song at the top of their own chart more than someone who only mentions it in final positions, even if more often.
