Scoring a fouled board

timanderson

Club session, on the 7th of 8 rounds we put in the score and the Bridgemate won't accept the lead card. Well, it turned out that the score was entered in the wrong direction (S rather than N) so all was well. But we thought at the time that the E/W hands were transposed after mis-pocketing at the previous table. Assume for a moment that this had happened. The White Book says to score the board in two fields, representing its two forms. Does the director have power to vary that if it does not seem fair? The problem being that if the board is only played twice in its 2nd form then the pairs may be robbed of a good score, as even 100% from 2 tables is only going to be fifty-something % when adjusted. Equally a 0% from 2 tables is rather arbitrary.

White Book 4.2.3.3 Small sub-fields
If the size of the group is at most three and is at most a third of the total number of results 
Neuberg’s formula is not used. Instead a group of two results is scored with a top as 65% and a 
bottom of 55%, and a group of three results is scored with a top of 70% and a bottom of 50%; 
with intermediate and tied results scored as for ordinary match-pointing.

The formula is used if A = 2 or A = 3, and E ≥ 3 A

Percentage = 60% + (M – (A – 1)) x 5%
Match points = ((M – (A – 1) + 12)/10) x (E – 1)

Note The small sub-field ‘formula’ awards scores that sum to 120% (AVE+ + AVE+) – 
this is as compensation to the pairs involved, for not getting a proper comparison

The other thing you might do is to continue having the board played in the incorrect form so as to create more equal sub-fields.

I've just noticed that it was the penultimate round, in which case you should just give both pairs AV+ and have it played in the correct form on the final round.

Thanks Gordon that all makes perfect sense.

A 0% (or any score) from a sub field of just two tables is going to have a much smaller effect on the final result than would (say) a 0% score from 10 tables.

That depends on the overall size of the event.
