Adjusting Scores

(changed 15 February 2021)

Assigned adjusted scores

You can assign any single result to a board.

Artificial adjusted scores

There are nine options:

  • =/=
  • +/-
  • -/+
  • +/+
  • -/-
  • =/-
  • =/+
  • -/=
  • +/=

The adjustments are in the order NS/EW, so +/= means AVE+ for NS, AVE for EW.
The subject of “multiple adjustments for one pair” is handled differently by some score systems. The method we have used is consistent with the wording of the laws, and verified by a WBF committee member. We compute scores like this:

  1. Compute "raw percentage" for boards played.
  2. Apply all AVE= adjustments.
    If your raw percentage is > 40%, apply all AVE- adjustments.
    If your raw percentage is < 60%, apply all AVE+ adjustments.
  3. Recompute the session percentage, and apply any final adjustments.
    This is when the AVE+ >60% or AVE- <40% happens. 

IMPs: teams and X-IMPs

For teams, the minus infractions AVE- results in minus three IMPs (-3). The adjustment is only applied to one side.
For X-IMPs, the minus infractions, AVE- results in minus two IMPs (-2). The AVE+ is plus two (+2).

If the adjustment "balances" then it goes in the normal IMP score columns.  That is:

  • =/= is just 0
  • +/- is +3 to the first team
  • -/+ is +3 to the second team

If the adjustment doesn't balance then the IMP score for the board is 0 and the adjustments go in the (invisible) separate column - so the total scores / VPs will be correct.

For head-to-head matches, ONLY =/=, +/- and -/+ are selectable.

When are adjustments seen?

  • When the Director makes an adjustment, the Director sees it immediately.
  • Under most circumstances players will see adjustments for a previous round as soon as the adjustment is made. If they disconnect and reconnect, they will see the score adjustments at the end of the round. 
  • A player in the lobby will only see the refreshed scores at the end of the round.

The simplified rule is this:

  • At the end of the round, all scores shown reflect the adjustments.
  • The Director always sees the refreshed scores immediately.

 

Clarification on Skipped boards

If a pair doesn't play a board that they are scheduled to play, Law 12 requires the director to award an adjusted score (eg. average, average plus, average minus).

Half Table: because you started with a genuine half table

  • A half table is not a table with lots of skipped boards.
  • The system manages their score correctly - they are awarded their average for the session for every board they do not play.
  • It does not give them 50% for every board they do not play.
  • As director, please do nothing.

Half Table: because you started with full tables, for example, but a pair left

  • A pair left the event. No substitute can be found, some rounds need to be skipped.
  • This now means you need to SKIP the boards for every round.
  • You can choose to adjust the score, via =/+  or -/+  etc.

Genuine skipped board, because of lateness, or bridge reason

  • A board needs to be skipped.
  • This now means you need to SKIP to make the skip happen.
  • You can allow the system to give =/= (default action)
  • You can choose to adjust the score, via =/+ or -/+  etc later, if one pair is at fault.

Half Table: because you started with a genuine half table, but somebody later sat in one seat, and the director accidentally clicked Play Round

  • Here, by accident, a person sat in one of the seats. Then, the director clicked Play Round.
  • They are now “part of the movement”.
  • This now means you need to SKIP the boards for every round.
  • You can choose to adjust the score, via =/+ or -/+  etc later.
  • This is not ideal. We plan to change the system to stop this from happening.
