How does Top pick (Single Transferable Voting) work?

Top pick judging uses the single transferable vote (STV) method to determine winners. STV is a ranked voting system designed to produce proportional outcomes.

Top pick selects winners but does not create a ranked list by default.

STV worked example

This example uses

  • 100 entries
  • 3 winners

Step 1: calculate the quota

The quota is the number of picks required to win.

Formula:

  • Number of entries ÷ (Quantity of winners + 1) + 1

Example:

  • 100 ÷ (3 + 1) + 1 = 26

Quota:

  • 26

Step 2: count first preferences

All judges’ first preference picks are counted. Each first preference is allocated to the chosen entry.

Step 3: select winners who meet the quota

Any entry that meets or exceeds the quota is declared a winner.

If all winners are selected, the process ends. If not, continue to the next step.

Step 4: transfer surplus picks

If a winning entry has more picks than required, the surplus is transferred. Surplus picks move to the next preference listed by those judges.

Example:

  • Entry receives 30 picks
  • Quota is 26
  • 4 surplus picks are transferred

Step 5: eliminate the lowest entry

If no entry reaches the quota:

  • The entry with the fewest picks is eliminated
  • Its picks are transferred to the next preference

Step 6: repeat until all winners are selected

Steps 3 to 5 repeat until all winners are chosen.

Good to know

  • Top pick selects winners, not a ranked order.
  • The leaderboard position does not indicate rank.
  • All winners are equal unless you calculate a ranked list.
  • The quota always rounds according to the formula.
  • STV ensures votes are not wasted where possible.
