How to read these numbers
Public counters. Subscribers, views and public video totals are displayed as captured. These are collected public observations. The first observation is not the channel's creation date.
Historical calculations. Net change is the last total minus the first total. Growth is net change divided by the starting total. The average uses elapsed calendar days. The median and largest daily change use only available adjacent daily intervals. Longer windows stay disabled until their starting baseline exists.
Precision and gaps. Subscribers and their changes are approximate. Unknown daily changes remain unavailable, while negative corrections remain negative. Observations are grouped by UTC date, not exact capture time, so daily movements are not exact rolling 24-hour measurements.
Scope. No revenue, private audience metrics, verification badge, global ranking or uncalibrated authority score is inferred from these counters. The directory and video library are limited to the records actually collected.
