Potential duplicates divided by registered voters, by county. The key runs from the lowest tier to the highest. The number in brackets is how many counties fall in each tier.
How these numbers are counted. The report's county table counts potential duplicate records. The statewide spreadsheet appears to count cases, where one case is a pair of records, so its figures run at about half. Each is shown in its own unit and labeled.
The ratio is a county's current potential duplicates divided by its registered voters. Tiers follow the report's Appendix A. Share resolved is the "overall % resolved" figure from the statewide spreadsheet, as the author gives it.
