Report a correction
What makes a report actionable
The most useful reports establish the real manufacture date independently of the serial number. In rough order of how much weight we can put on them:
- Manufacturer confirmation, from their support team or warranty records.
- An original purchase receipt or invoice with a date.
- A print date on the owner's manual, usually near the publication number.
- An installation record from a fitter or builder.
- Service documentation showing the format we got wrong.
“This seems too old” is worth sending too, but it is much harder to act on. If several reports say the same thing about the same rule, that is a signal in itself.
What we do with it
Reports are reviewed against the documentation behind the rule. If the rule is wrong, we fix it, update the sources and record the revision. If the rule is right but the result was misleading — usually because a caveat was not prominent enough — we improve the wording instead. Either way the change is visible on the methodology and sources pages.
Privacy
Serial numbers are masked before storage, reports are visible only to administrators, and an email address is used solely to follow up on your report. Reports are deleted within 24 months of being resolved.
