RollCall documentation
Every number, and the reasoning behind it.
How every RollCall number is built — and the research behind it. Each metric on your dashboard has a page here — what it means, how to use it, exactly how it's built, and the 44 independently-verified sources it stands on.
Three things hold across every page:
- A room is only compared with itself. A venue's night is read against its own history, never ranked against a bigger or smaller room.
- Measured and estimated are never dressed up as each other. An exact number looks exact; an estimate carries its band. Read why →
- What we can't see is named, not guessed. "No reading" is a state, never a zero. Read why →

1 verified sourceConcepts
The ideas the metrics share.
Measured vs. estimated
When RollCall shows an exact number, when it shows a band, and why it never dresses one up as the other.
How confidence and baselines work
What a "typical night" is built from, the floors that hold a comparison back until there is enough history, and why a short record is treated as noise.
Why we don’t show certain numbers
The things RollCall deliberately withholds — group totals of capacity, refund rates on the wrong denominator, uncalibrated occupancy — and the reasoning behind each.
