Every pair in a group plays every other pair once. A win is worth two points and a defeat is worth none. When the group finishes, pairs are ranked by points.
When points are level
Net points come next: the points you scored minus the points scored against you, across every group match. Win 21–15 and lose 18–21 and your net is +3.

What changed from the spreadsheet
Our old spreadsheet quietly broke any remaining tie by the pair's number in the group. That meant the luck of the draw could decide who reached the Gold bracket. The new system never does that: an unbreakable tie is flagged to the desk and settled openly.
