What they publish, and what went further than their normal.
Their last 50 uploads
The same maths as your own channel
30 days, then deleted
Which of their videos actually went further
Not their top three, because every channel has a top three and naming it says nothing. A video counts as a breakout when it reaches two and a half times the median of its own format on that channel, which is a bar a channel can fail to clear. Shorts are compared with shorts and long cuts with long cuts, because pooling them makes every short on a long-form channel look like a hit.
The same arithmetic on both sides
Cadence, format mix, length bands and posting days are computed for a watched channel by exactly the module that computes them for yours, with the same sample sizes and the same refusals. A comparison against a number worked out a different way tells you nothing.
What it will not show you
No estimated earnings, no “opportunity score”, no tag lists scraped from their uploads. Those numbers are either unavailable through the API or invented, and a product that shows one invented number has taught you not to trust the measured ones.
Their numbers are not kept
The YouTube Developer Policies cap how long an application may hold data about a channel that did not authorise it, at thirty days. Runsheet deletes on that schedule nightly. A channel you are still watching is re-read and stays current; one you stop watching goes.
What this feature will not do, stated where you can read it before paying.
- Public data only, which is what the YouTube API exposes for a channel that is not yours.
- No estimated revenue. Every number sold as one is a guess with a confident font.
- No view curves. YouTube reports another channel's current totals and nothing else, so a video published this week is measured against the same median as one from two years ago.
