LAW 78
METHODS OF SCORING

A. Matchpoint Scoring

In matchpoint scoring each contestant is awarded, for scores made by different contestants who have played the same board and whose scores are compared with his, two scoring units (matchpoints or half matchpoints) for each score inferior to his, one scoring unit for each score equal to his, and zero scoring units for each score superior to his.

B. International Matchpoint Scoring

In international matchpoint scoring, on each board the total point difference between the two scores compared is converted into IMPs according to the following scale:

Difference         Difference             Difference       in points  IMPs    in points     IMPs     in points     IMPs  20 -  40   1       370 -  420    9       1500 - 1740   17  50 -  80   2       430 -  490   10       1750 - 1990   18  90 - 120   3       500 -  590   11       2000 - 2240   19 130 - 160   4       600 -  740   12       2250 - 2490   20 170 - 210   5       750 -  890   13       2500 - 2990   21 220 - 260   6       900 - 1090   14       3000 - 3490   22 270 - 310   7      1100 - 1290   15       3500 - 3990   23 320 - 360   8      1300 - 1490   16    4000 & upwards   24

C. Total Point Scoring

In total point scoring, the net total point score of all boards played is the score for each contestant.

D. Special Scoring Methods

Special scoring methods are permissible, if approved by the sponsoring organization. In advance of any contest the sponsoring organization should publish conditions of contest detailing conditions of entry, methods of scoring, determination of winners, breaking of ties, and the like.

LAW 79
TRICKS WON

A. Agreement on Tricks Won

The number of tricks won shall be agreed upon before all four hands have been returned to the board.

B. Disagreement on Tricks Won

If a subsequent disagreement arises, the Director must be called. No increase in score need be granted unless the Director is called before the round ends as specified in Law 8 (but Law 69 or Law 71 may supersede this provision when there has been an acquiescence or a concession).

C. Error in Score

An error in computing or tabulating the agreed-upon score, whether made by a player or scorer, may be corrected until the expiration of the period specified by the sponsoring organization. Unless the sponsoring organization specifies a later time, this correction period expires 30 minutes after the official score has been made available for inspection.

---

An earlier time may be specified when required by the special nature of a contest.
