Everything you wanted to know about the Selection Trials Scoring

Hi friends! Technically, the line "But were afraid to ask" is the second part of a title like this.

In this post, we are going to try and explain to you the detailed methodology that the BFI has worked out to select the best 3 pairs possible to represent the country. We would like to state that we have worked it out to the best of our understanding and ability. If, in actuality, there is some difference, then the error is ours and we apologise for any in advance.

First of all, for ready reference, let us have the report as at the end of yesterday, presented so diligently by T C Pant, available for ready reference. You may fetch it by clicking here

The pairs are evaluated on 4 aspects as given below (with their weightage in percentage in brackets)

1. Ranking Points, i.e. performance in Ranking Events (35)
2. Head to head performance in the camp (55)
3. Number of wins during the camp event (5)
4. Compliance of Convention Card to WBF Norms (5)

 

Under each head, the top performer gets the maximum   weightage for the heading. The other pairs get a pro rata fraction of the total weightage for the ranking points. Let us elaborate further

Ranking Points

If you look at the document above, you will see that Keyzad and Tewari have the maximum number of ranking pointsat 446.40. Since the weightage for Ranking points is 35%, they get to score a maximum 35 on this criterion.

Sumit and Laltu have got  442.41 ranking points. So, their score in this criterion is calculated as 441.41/446.40*35 %= 34.69.

Head to Head Performance

As of now, Kaustabh Nandi and Sagnik Roy are leading the field with 98.55 VPs. Since the weight for the event is 55%, they get a score of 55 on this parameter.

Kachchu and Bardhan, who have obtained 90.09 VPs, score 90.09/98.55*55% = 50.28 on this parameter.

Win / Loss Ratio

Kaustabh and Sagnik have played brilliant bridge to win all 7 of their matches. Since the weight for this factor is 5, they get a score of 5 on this parameter.

Jaggy and Sandeep, with 4 wins score 4/7*5% = 2.86.

It is worth pointing out here that a win-loss ratio of 100% is not necessary to score 5 points. If the best number of wins had been 6 instead of 7, that would have obtained a score of 5.

Had the maximum number of wins been 6, then Jaggy and Sandeep's score would have been 4/6*5% = 3.33. This example is just being given to show how the score is calculated and is not a reflection of the current status.

Convention Card

Having a convention card which is complete and fully descriptive is essential for all international championship events. Hence, the convention cards submitted by all contestants have been evaluated on an absolute score of 5 for the final component of the total score.

Total Score

For simplified reading, we present the total score of all contestants as of last evening.

If you look at Mr. Pant's document, you will see that Keyzad and Tewari's score is 35 for ranking points, 44.12 for camp performance, 3.57 for win loss percentage and 5 for the convention card making a total of 87.69.

The total scores of other contestants will be calculated in a similar way.

 

From 12 contestants in the first elimination, the field will be pruned to 8 for the second elimination and 6 for the finals over the coming few days. A similar pattern of evaluation will be followed for each of the final sets.

Conclusion

We hope this article has made it easier for a lot of you to understand how the scores are arrived at. You may post any clarifications you require in the comments section of this article.
