The BFI Technical Committee has proposed the following methodology for the upcoming National Camp 2024 as under. Suggestions are welcome to be posted to bfi-technical-committee@googlegroups.com for any changes to be made if needed. The dates of the events announced earlier remain as it is.
REGISTRATION FOR TRIALS: www.bridgewebs.com/ellisbridgegymkhana
Stages to be adapted for each event:
| No of Entries | 16 or more pairs | Less than 16 pairs |
| Format | Two elimination rounds Elim 1 -> Elim 2: 12 pairs Elim 2 -> Finals: 8 pairs | One elimination round Elim -> Finals: 8 pairs |
These procedures refer to Open/Men, Mixed and Ladies categories. The senior trials are handled separately. The selection trials will be held live under guidelines issued by SAI in form of evaluation of coaching camps and competitions. The camps will consist of Elimination and Final stages.
WEIGHTAGES AT EACH STAGE:
The following Weightages will be given to camp performance, ranking points and carry forward from elimination stage only.
All the camp performance points, carry forward and ranking points will be translated in terms of Victory Points
For clarification: Round = 1 Match. Stage = Sum of all matches played in that league
| Stages (Open/Mixed/Women) | VP Score | Ranking Points Weightage | Carry Forward Points (1st Elim) | Carry Forward Points (2nd Elim) |
| Elimination – 1 | Actual VP Score | 1.5 VPs per match in that stage to topper and proportionate VPs to others with last Qualifier getting zero Vps | ||
| Elimination – 2 | Actual VP Score | 1.5 VPs per match in that stage to topper and proportionate VPs to others with last Qualifier getting zero Vps | 0.5 Vps per match to topper and proportionate VPs to others with last Qualifier getting zero Vps | |
| Final | Actual VP Score | 1 VP per match in that stage to topper and proportionate VPs to others with last Qualifier getting zero Vps | 0.5 Vps per match to topper and proportionate VPs to others with last Qualifier getting zero Vps |
The Technical Committee has recommended to convert all the points in Victory Points (VP) and the following formula has been suggested
- All stages will be of single or double round robin basis. The weights allocated for Ranking Points or Carry Forward Points will be multiplied with the number of rounds to be played in that stage.
- The last qualifier will obtain Zero Vps for Ranking points as well for Carry Forward Points and other pairs will be proportionately adjusted as per their score.
- Scoring will be Cross IMPS method averaged to number of comparisons at all stages. There will be no outliners removed and the net IMP difference will be in decimals. If the partial decimal difference is upto 0.5 it will be rounded off to lower integer and 0.5 and above difference will be rounded off to next higher integer.
- The net difference of IMPS (in full integer after rounding off) for any match played will be converted to VPs as per applicable WBF Continuous scale for that round.
NEW PARTNERSHIPS:
Points are awarded exclusively for partnerships only. However, individual players forming new partnerships can avail 30% of the highest-ranking points awarded to him/her in any partnership based on the total ranking points published for the respective selection cycle in contention provided both individuals are part of the original qualified list of pair of that respective category. The sum of both the total ranking points calculated above will be actual ranking point awarded for that respective pair.
FORMULAS TO BE APPLIED FOR CARRYOVERS:
Elimination 1
Formula for Carryover
1.5* n * (RP – RP_min)/(RP_max – RP_min)
n – No of Matches to be played in E1
RP – Ranking points of the pair
RP_max – highest Ranking points amongst all participants of E1
RP_min – lowest Ranking points amongst all participants of E1
E1-E2
Ranking will be done based on Total VPs scored in E1 + Ranking Points C/O (in VPs)
Formula for Ranking point Carryover
1.5* n * (RP – RP_min)/(RP_max – RP_min)
n – No of Matches to be played in E2
RP – Ranking points of the pair
RP_max – highest Ranking points amongst all participants of E2
RP_min – lowest Ranking points amongst all participants of E2
Formula for Camp Performance Carryover
0.5* n * (VP – VP_min)/(VP_max – VP_min)
n – No of Matches to be played in E2
VP – VP Score of the pair in E1 not counting carryover
VP_max – highest E1 VP Score amongst all participants of E2 not counting carryover
VP_min – lowest E1 VP Score amongst all participants of E2 not counting carryover
E2-Final
Ranking will be done based on Total VPs scored in E2 + Ranking point Carryover + VP Score(Elim-1) Carryover
Finals
Formula for Ranking point Carryover
1.0* n * (RP – RP_min)/(RP_max – RP_min)
n – No of Matches to be played in Finals
RP – Ranking points of the pair
RP_max – highest Ranking points amongst all participants of Finals
RP_min – lowest Ranking points amongst all participants of Finals
Formula for Camp Performance Carryover
0.5* n * (VP – VP_min)/(VP_max – VP_min)
n – No of Matches to be played in Finals
VP – VP Score of the pair in E2 not counting carryover
VP_max – highest E2 VP Score amongst all participants of Finals not counting carryover
VP_min – lowest E2 VP Score amongst all participants of Finals not counting carryover
Final Ranking will be done based on Total VPs scored in Final + Ranking point Carryover to Final +
VP Score(Elim-2) Carryover to Final
