# Scoring Method

Currently, there are `23` rules for experience scoring, divided into three categories: `Performance`, `Experience`, and `Best Practices`. Satisfying the rule requirements earns a score of `100 points`, otherwise, the score is `0 points`. Finally, the total score is calculated based on the weights of each rule and the formula.

## Formula for Calculating Total Score

1. Multiply the score of each item by its corresponding weight.
2. Add up all the products to get the total weighted score.
3. Add up all the weights to get the total weight.
4. Divide the total weighted score by the total weight to get the weighted average score.

The formula can be expressed in data as:

```math
\text{Total Score} = \frac{\sum_{i=1}^{n} Score_i \cdot Weight_i}{\sum_{i=1}^{n} Weight_i}
```

### Notes

> Rules with a weight of 0 do not participate in scoring and are only Note.
> Rules that are not met in the detection process will not participate in scoring.
> The scoring conditions for each rule may also be adjusted with the version update of the IDE.
