Calcul de l'eco index

Bonjour,

En regardant le code qui calcule l'eco index je trouve la formule suivante ([code](https://github.com/cnumr/GreenIT-Analysis/blob/master/script/ecoIndex.js#L34)):

`return 100 - 5 * (3*q_dom + 2*q_req + q_size)/6;`

Or sur le site [ecoindex ](https://www.ecoindex.fr/comment-ca-marche/), on trouve la suivante:

100 - (3*q_dom + 2*q_req + q_size)/6

Il y a-t-il une erreur quelque part?

Start in script/ecoIndex.js at the formula around line 34 and compare it with the calculation described on the linked EcoIndex site. Verify which multiplier is correct for the project’s q_dom, q_req, and q_size values; done means the implementation and its documented explanation agree, with the discrepancy resolved.
