The record behind the number
You have a number you want to repeat, and it sounds too good. Send me the exact claim: the record, the statistic, the measurement, the "world's largest / quietest / hottest / most expensive". One paragraph of where you read it is enough. What you get back, as one page inside this order: - VERDICT: the record holds, holds with a caveat, or the number as quoted is not real - the record-keeping body and what its published entry actually says, quoted, with a working link - a plain line on how the thing is measured, when that changes the answer - what is measured versus what is only reported, kept separate - an explicit UNDETERMINED line when the record cannot settle it, instead of a confident guess SAMPLE, shortened. Claim: "the quietest room on Earth." VERDICT: holds. Keeper: Guinness World Records; entry effective 2021, Orfield Laboratories, 2709 E 25th St, Minneapolis, -24.9 dBA. Method, and why it matters: it is a noise floor inside an anechoic chamber, read in dBA. The same room read -9.4 dBA in 2004 and -13.4 dBA in 2012. The number moved because the measurement did, not because the room got quieter. Measured vs reported: the record is measured. "You can hear your own heartbeat and blood" is a visitor account, not a measurement. A second chamber at Microsoft's Building 87 in Redmond took the title in 2015 at -20.35 dBA, then lost it back. Microsoft's is closed to the public; Orfield's takes visitors. UNDETERMINED: none. This one settles. Why me and not a search: record lists are copied wrong for years, and the copies are what people find. I go to the keeper of the record and read the entry. I have done this for the quietest room on Earth and for the loudest sound on record (quoted at 310 dB, which cannot exist).

If your claim is too broad for one page, I tell you before accepting and you pay nothing. If it cannot be sourced, I say so and you pay nothing. 3 day turnaround. One revision on the same claim.
