Category timeline
Where the broadcast’s time went. A switch is placed midway between the last sample of one category and the first of the next, because that is as precisely as sampling can locate it.
| Category | Started (UTC) | Duration | Avg viewers | Peak | Hours watched |
|---|---|---|---|---|---|
| Science & Technology | 9h 9m | 16.3K | 21.3K | 149.7K |
How this broadcast compares
This broadcast averaged 16.3K viewers, 30.2% below the channel’s 30-day average of 23.4K viewers.
A percentile needs at least five finalised streams in the last 90 days; we have 4.
How we measured it
- Samples collected
- 256
- Sampling coverage
- 99%
- Data confidence
- 99%
We check a live channel every few minutes rather than continuously, so these numbers are estimates built from 256 observations. Coverage is the share of the broadcast those observations account for; confidence combines that coverage with how many samples we took and whether we saw the stream end. Time we did not observe is excluded from the averages rather than filled in.
What stands out
- This stream averaged −30.2% versus the channel's 30-day average of 23.4K viewers.
