Followers

The axis starts at zero, so a week of growth on a large channel looks small — which is the honest reading.

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.

Engagement measurements

How much chat this channel produces for its audience, and how steady its viewer count is. Both are observations, not judgements.

Chat participation
20.2 per 1,000 viewers

Median for similar channels: 13.6

From 44 sampled windows of public chat.

Viewer count steadiness
4.13

Median across measured channels: 1.77

Variation in the viewer count between readings, relative to what an audience of independent people would produce. Higher means more variation.

Messages per chatter
1.4

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.
