# Steam Player Level Percentiles
This repository contains Python code to query percentiles of player levels, to infer the total number of Steam players.
![Illustration cover][img-cover]
## Requirements
- Install the latest version of [Python 3.X][python-download-url].
- Install the required packages:
```bash
pip install -r requirements.txt
```
## Usage
```bash
python player_levels.py
```
To apply the method to achievement unlock percentages, run:
```bash
python achievements.py --app-id 788100
```
## Assumption
Let us assume that, in order to compute the percentages, Valve:
- divides the total number of players by 100,
- then truncates it.
For instance, with `16,483,473` players at level 1, and `104,857,600` players in total,
then the percentile would be:
```
16,483,473 / 1,048,576 ~ 15.719864845275879
```
which is finally displayed as:
```
https://api.steampowered.com/IPlayerService/GetSteamLevelDistribution/v1/?player_level=1
```
```json
{
"response": {
"player_level_percentile": 15.719864845275879
}
}
```
## Results
```
Least Common Multiple: 1048576
```
Following our assumption, this would mean that the total number of Steam players is
a multiple of `104,857,6XY`, where `XY` are unknown digits.
This is not super useful info.😅
## Truncation
> [!Note]
> Interestingly, the least common multiplier is a power of 2.
$$
1048576 = 1024^2 = 2^{20}
$$
This could indicate a truncation of the numbers in binary representation,
which would prevent the estimation of a total number of Steam players
of the order $2^{28} - 2^{30}$, i.e. hundreds of millions.
