Across 993 people called in the audit, the first attempt reached 331 for the first time. The second reached 90 more, the third 48.
The long tail
Fourth and later attempts took 544 calls to reach 19 people for the first time. 542 of the 993 people were called three or more times; 25 were called six times.
The rule
Two attempts at most. Retries stop the moment someone picks up, and a person who has already talked is never re-dialled by the qualifier. They go to a person or a closing call instead.
