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 pointsIMPs      in pointsIMPs      in pointsIMPs
20 - 401      370 - 4209      1500 - 174017

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.
