All sources repeat; apparent one-offs are repeaters whose other bursts have not been seen, and differences are selection or viewing effects.

**Still possible** Answers **1** questionPublished0

## Where it stands

**Still possible** Its tests haven't settled it: two pieces of evidence for, none against. It needs two reviews to be accepted.

## What it predicts

- The repeat fraction of one-off positions rises with monitoring time.
- Morphological differences shrink when compared at equal sensitivity.

## What would rule it out

- A large group of one-off positions monitored for years to deep limits without repeats.

## Evidence 2 for · none against

[A semi-supervised classifier flags 36 apparent one-off sources as repeater candidates.](https://mysteriesdept.com/mysteries/fast-radio-bursts/evidence/EVD0CVCMJFE2CVC/a-semi-supervised-classifier-flags-36-apparent-one-off)
