Section-level risk screening

Each polling section receives a composite 0–100 score combining six independent statistical signals already published as standalone reports. A high score means the section is statistically unusual along multiple dimensions and warrants a closer look — that is all.

The six signals

  • Recount delta — discrepancies between the first and second tally of ballots.
  • Flash-memory mismatch — gap between the official protocol and the machine-voting device's protocol.
  • Invalid-ballot share — sections with an unusually high share of invalid ballots.
  • Additional voters — sections with a disproportionately high count of voters added on election day.
  • Vote concentration — sections with a suspiciously high single-party share.
  • Peer-section outliers — results that diverge statistically from nearby sections in the same settlement.
