| Appendix I - WBF
Carry-over Formula (in the supplementary conditions of contest) |
There will be a carry over in all
matches of the knockout phase. The carry over will be half
or one-third of the IMP difference in the meeting of the
teams in the round robin. It will be half if the highest
ranked team in the round robin won the match against their
opponents and one-third if the highest ranked team in the
round lost the match to its knock out opponent.
The maximum carryover used in any event will be:
- 8 for a 32 board match
- 12 for a 48 board match
- 16 for a 96 board match
- 20 for a 128 board match
In the case of the World Transnational Open Teams, if one or
more quarter-final matches do not have a carry over then no
carry over will be applied to any quarter-final matches.
Likewise, if one semi-final has a carry over, but the other
does not, then no carry over will be applied to either
match. |
