This profile has enough tracked history to be listed in search engines. How these numbers are calculated.
Every figure below is measured from broadcasts we observed. Percentage changes appear only where the previous period had enough data to compare against.

Highest peak we have tracked: 968 viewers on August 30, 2026.
All-time figures cover only what we have observed since we began tracking this channel on . They are not the channel’s lifetime totals on Twitch.
Daily figures for the last all time. A day we never observed is drawn as a gap, never as a zero.
EJ_SA, last all time.
Total followers recorded each day over the last all time.
The axis starts at zero, so a week of growth on a large channel looks small — which is the honest reading.
The same numbers the charts draw, as a table.

How much chat this channel produces for its audience, and how steady its viewer count is. Both are observations, not judgements.
Median for similar channels: 15.7
From 22 sampled windows of public chat.
Median across measured channels: 1.82
Variation in the viewer count between readings, relative to what an audience of independent people would produce. Higher means more variation.
How much each participating account says. Very high values mean a few accounts are doing most of the talking.
Chat figures come from sampling the public chat of EJ_SA for short windows; they count accounts that sent a message, not people watching silently, and most of any audience watches silently. What these numbers do and do not mean.
Generated from the figures on this page. No estimate is stated more precisely than the measurement supports, and nothing here claims a cause.

Times are UTC. Average and peak viewers come from periodic sampling of the live broadcast, so they are close estimates rather than exact platform figures. A stream marked “partial data” had gaps in our sampling; the unobserved time is excluded from its averages rather than filled in.
Rows marked “Archive” come from Twitch’s public VOD record. Date and duration are exact; viewership was not tracked at the time.
