Weird/Broken addon rating system

Can someone tell me where the star ratings for addons are coming from?

The only addon rating system i've came across are the ones on a users' profile. There you can give either a thumbs up or down, however it doesn't seem to affect the star rating, or does it?

Also why is that rating system to be found on the profile, but not on the page of the addon itself?

I'm genuinely confused.

yea it's really weird. The thumbs up do affect the star rating, it seems like the up vote down vote ratio is remapped to 0-5.

Ah i get it now.

For some reason everything has already your own thumbs up, however this first one does not actually count. I would prefer it to be 0, if there's no thumbs up.

I assume there can only be either no stars, or 5 stars as soon as you get your first thumbs up. Means that there's no meaning to the stars at all, it just shows your thumbs up count between the brackets.

I would suggest to either remove the star rating system, or implement it properly.

And move the rating system to the addon page.
