Frequently asked
Frequently asked questions
What does the ModSignal Score mean on this page?
It is a 0–100 momentum signal combining 7- and 30-day subscriber velocity and acceleration. Higher means the mod is gaining adoption faster relative to its own baseline — not that it is bigger.
Are these the real Steam Workshop numbers?
Yes. Subscribers, favorites and views are read from the public Steam Workshop page and stored as snapshots; the deltas are computed from those snapshots, never estimated.
How is the rank computed?
Rank is the mod’s position among active mods of the same game, ordered by total subscribers. It is recomputed every collection cycle.
