The answer, from the board
STALE states age, not lateness: the newest report ReserveBeat holds for this token is older than the cadence expected for it, which can happen while the next report is not yet due.
This answer contains a figure ReserveBeat computes rather than one an issuer published. It is labelled as computed wherever it appears, and the exact calculation is written down. How every published figure is derived

The cadence is a description of past reports, not a commitment by Circle, and a period missing from the list is one the board holds no report for. The next-report date is computed by ReserveBeat from the cadence and the latest report's lag; the data definitions page states exactly how.

Questions
Common questions
Where do the answers on these pages come from?
Each page reads ReserveBeat's own board when you load it. Figures published by issuers pass through exactly as they appear in the attestation reports ReserveBeat parsed; anything ReserveBeat works out itself is labelled as computed and the calculation is written down.
Why is an answer sometimes empty?
Because ReserveBeat holds nothing for it. An empty cell is never filled with a zero, an estimate, or a figure carried over from somewhere else, and a whole answer is withheld rather than shown stale while the board is under review.
Do these pages define the terms they use?
No. Definitions live in the learn section and are written once. These pages answer questions whose answer is a figure or a state read from the board, and they link to the learn section for the vocabulary.
How often do the answers change?
Whenever the underlying board changes. Nothing on these pages is cached as text, so a new attestation report or a correction shows up on the next page load without anyone rewriting the page.
