Another tidbit from the report I'm writing about #fusil:
The 52 issues filled correspond roughly to 30% of all the crashes (issues with "type-crash" label) and 2% of all issues (features requests, bugs and invalid issues) reported in the #CPython issue tracker during the six months period covered by the report.
Hits and new issues don't appear at a steady pace. It seems that there are long periods of no or nearly no new issues, followed by rapid finding of new results.
