How to score a vacant pair?

We offer 3 different ways to score a vacant pair:

The options is found at the Scoring tab during tournament / game creation. Notice the “(edit)” – it means you can edit the selected vacant scoring  principle (Notice – only until the tournament is started) by clicking here:

Average scoring principle:

Scoring will be equal to the average scoring

Average plus scoring principle:

As shown Average plus is equal to 60%.

Neuberg Formula scoring principle:

The Neuberg Formula is another calculation principle for assigning score to non-played boards.

For serious games where rating points are on stake, this principle is a more fair principle of assigning percentages.

“Neuberg Formula” will compute the actual played boards and assigned the same percentage to the non-played boards

The different principles is maybe best described by an example:

Assuming Pair A have achieved a score of 63% after 6 of 7 rounds.

Average scoring principle:

At round 7 pair A was the vacant pair

Everyone got an average scoring equal to – for example 50% – an their vacant round of 4 boards then pair A would finished with 62%. The last 4 x 50% boards hereby pulled their total percentage score down.

Average plus scoring principle:

At the vacant table everyone got an average plus scoring equal to 60% – before the last 4 boards then pair A would have 63%. The last 4 x 60% boards also here pulled their total percentage score down from 63% but only slightly.

Neuberg Formula scoring principle:

Neuberg Formula will calculate a pair’s score as if no vacant table have been present – for example 63% in the example – and then assign the calculated 63% percentage to the pair’s non-played boards as well.

Refer to this document for technical details. The mathematics behind the formula is implemented in the B+M system.
