## Quality formula for the article
**Schirinzi** ^{EN}

$$Quality=1/c∑↙{i=1}↖c nm_i-RS=1/6(0.68+0+7.69+0+0+0)$$

where:

- $nm_i$ is normalized quality metric $i$
- $c$ is the number of quality metrics
- $RS$ is the reducing score (if exists)

The results of the calculations may be slightly different because of rounded values of normalized metrics in formulas
