Top Packages Algorithm
Pseudo rolling average
Every package loses 5% of its score every day.
An open source package will gain 1 score for each unique download, whereas a non-free package will only gain 0.1 score.
A package currently only gains score through downloads. In the future, a package will also gain score through reviews.
Seeded using a legacy heuristic
The scoring system was seeded (ie: the scores were initially set to) 20% of an arbitrary legacy heuristic that was previously used to rank packages.
This legacy heuristic is as follows:
forum_score = views / max(years_since_creation, 2 weeks) + 80*clamp(months, 0.5, 6) forum_bonus = views + posts multiplier = 1 if no screenshot: multiplier *= 0.8 if not foss: multiplier *= 0.1 score = multiplier * (max(downloads, forum_score * 0.6) + forum_bonus)
As said, this legacy score is no longer used when ranking mods. It was only used to provide an initial score for the rolling average, which was 20% of the above value.
