Activity pattern

Why r/cryptography is classified as Steady

Oscylo reads the newest 52 weeks of posts, comments and unique contributors and gives each subreddit one of the patterns below. The figures behind the label are shown beside it.

Activity patternSteady

r/cryptography shows no strong, consistent direction across contributions and contributors. Individual weeks can still vary.

How the label is read

Concentration1.90×
2.5×

The busiest four weeks against the quietest, with the yearly trend taken out. At 2.5× or more the year counts as concentrated: Seasonal if the busy weeks came at the same time in earlier years, Event-driven if they did not, and Variable when there is too little history to tell.

Posts and comments, yearly trend−2.4%/yr
−20%0+20%

To be considered Rising, a subreddit needs posts and comments up 20% or more over the year, with unique contributors also rising. Cooling is the same in reverse, and anything between is Steady. The trend is a line fitted through all 52 weeks, so a single busy week barely moves it.
