Assigned adjusted scores
You can assign any single result to a board.
Artificial adjusted scores
It is possible to assign fixed and variable artificial scores. Scores with symbols (+, =, -) are variable and numbers (40, 50, 60) are fixed. For example, if a pair is given Avg+, they get 60% or their own score, whichever is higher. If a pair is given 60, they get 60% always. Similarly for Avg- and 40%.
When adjusting the score, the first box contains +/-, +/=, etc. The second box controls which type of adjustment is made:
~ means that the score is Avg+/Avg-
= means that the score is fixed 60%/40%
The adjustments are in the order NS/EW, so +/= means Avg+ for NS, Avg= for EW.
The image on the left shows Avg + for North/South and Avg - for East/West. Notice the ~ symbol which indicates that the scores change based on the session score for the pair.
When should this option be used?
- In Mitchell and Howell: to determine the pair’s own average the entire set of boards is used. In this case the standard Avg+/Avg- options should be used.
- In Swiss, to determine the pair’s own average, only the set of boards in the current match or round are used.
- In a Swiss event with short rounds (up to 4 boards), the NBO may advise using the 60/40 adjustment.
USEBIO export and external scoring systems
In the USEBIO file, the matchpoints are calculated according to the adjustment you have specified. However, the SCORE will show the same text, eg “A6040”, for both types of adjustment. This is because the USEBIO format does not support both types of adjusted score. Many scoring systems do not have this feature. If you choose to import the USEBIO file into a scoring application and rescore it, it may rescore a 60/40 as an Avg+/Avg-.
What do the adjustments look like on RealBridge screens?
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:
- Compute "raw percentage" for boards played.
- Apply all Avg= adjustments.
If your raw percentage is > 40%, apply all Avg- adjustments.
If your raw percentage is < 60%, apply all Avg+ adjustments.
- Recompute the session percentage, and apply any final adjustments.
This is when the Avg+ >60% or Avg- <40% happens.
IMPs: teams and X-IMPs
For teams, the minus infractions Avg- results in minus three IMPs (-3). The adjustment is only applied to one side.
For X-IMPs, the minus infractions, Avg- results in minus two IMPs (-2). The Avg+ 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.
For more about this topic please refer to EBU White Book
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).
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 a director, please do nothing.
Started with full tables, but a pair left
- A pair left the event. No substitute can be found, some rounds need to be skipped.
- EBU Whitebook (2.4.4) states: If a contestant withdraws before half of the session is completed, all scores obtained against
that contestant are cancelled. To do this, you must use the destroy pair functionality in Advanced. (See Game in Progress)
- This now means you need to SKIP the boards for every future round.
- You can choose to adjust the score, via =/+ or -/+, etc.
Started with a genuine half table, but the seats still appear open
- The likely cause here is a person sat in one of the seats by accident and the director clicked Start Round 1.
- They are now “part of the movement”.
- You will need to remove this spurious partnership from the records. To do this, you must use the destroy pair functionality in Advanced. (See Game in Progress)
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.
