The surge_score formula
surge_score = (p_0 − μ) / σ
- p_0: posts plus comments in this week.
- μ: the mean weekly posts plus comments over the previous 4 weeks.
- σ = max(population standard deviation of the previous 4 weeks, √μ).
Scope and method
- Source
- Based on publicly visible Reddit content; observation_status = archived_snapshot (archived snapshot).
- Week
- 2026-W44 (ISO week): 2026-10-26 to 2026-11-02 (UTC); the baseline is the previous 4 weeks.
- Data cutoff
- Data cutoff (data_cutoff) 2026-10-29T21:32:32Z; snapshot computed at 2026-11-05T11:32:35Z (UTC).
- Coverage
- Coverage for this week is coverage_ratio = 0.5568, with the warning WINDOW_EXCEEDS_DATA_CUTOFF (the end of the week falls after the data cutoff, so this week's data is incomplete).
- List scope
- Site-wide only, with no industry split and no industry filter.
- Inclusion
- Communities below the minimum sample, or without 5 complete weeks of data, are not included, so this table has only 9 communities.
- Calibration
- The figures on this page are uncalibrated snapshot values.
