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
- Not measured yet
- Viewer count steadiness
- 2.88
Median for similar channels: 8.5
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.
Chat figures come from sampling the public chat of 夜乃すみ 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.
