Observations, without extrapolation
Aggregate /LUSERS counters, exactly as reported by the server. “Invisible” refers to IRC user mode; “operator” means a network operator, not a channel operator. No identities or conversations are collected.
The 251 total and the global 266 total retain their separate scopes. Server-reported peaks are different from the maxima observed here. Ratios use only counters present in the same sample; they measure neither unique audience nor actual average channel size.
Net change does not count individual connections and disconnections. Coverage estimates measured time slots, never network uptime. Gaps and unknown values remain visible; no curve is extended artificially.
History uses fixed elapsed durations, with at most 90 days retained. The previous period ends strictly before the selected period starts: no observation is counted twice. Comparison columns use sample means and require at least two observations for that counter in each period; unequal collection coverage can affect the result. A zero previous mean has no percentage change. Dashed curves align elapsed offsets, not local calendar hours across daylight-saving changes. CSV exports contain only the selected period.
History: 90 days. Times use your browser’s local time zone.
Calculation method and accessible observations
Δ = last minus first known value in the selected range. Mean, median, P95 (nearest rank) and population standard deviation use observations without time weighting. Cards and the summary table keep the full range when a chart is zoomed. A collection gap is more than 2.5 sample intervals between observations; range boundaries are not counted as gaps.
