How we find flaps
- Plain rules, no model: reports within 37 miles and about four months of each other are grouped, and a group counts only when it is at least 5 times what that place usually sees over the 10 years either side.
- A flap needs at least 3 reports from at least 3 separate documents: one article listing six sightings is one telling.
- Copies are not confirmations: a story reprinted in thirty papers counts once.
- Investigator logs (BFRO, NAWAC, the Loch Ness Register) are left out, because a busy field season looks just like a flap.
- Only reports placed to a town or county and dated to the month are used. A flap is a burst of reports, not proof of a creature: panics, hoaxes and newspaper fashions make flaps too.
