Local scores vs National scores
On the day of the event, each player will receive a
percentage score as usual, based on the result within the
club. This is the pair's Local Score. Once all the
results are matchpointed nationally, the pair will also
receive a National Score. The National Score is more
accurate than the Local Score, because it is not dependent
upon random results in a small field. The final results are
based on the National Score.
Your National Score may be very different from your Local
Score. For example, say your opponents bid a normal 4H
contract, but every other pair in your room misses it. You
will get an unlucky 0% for this board. However, once the board is
scored nationally, you may find that lots of other pairs
also bid it, and you end up with 40% for the board (and your
opponents, instead of 100%, score 60%). Because of this, an
extreme Local Score of say 70% will generally convert to a
more normal National Score of 60%.
It is theoretically possible to finish 1st in your club
on the day (after lots of top boards), yet not be the top
pair from your club in the national rankings (because all your
'good' boards turn out to be average when compared nationwide).
In particular, a pair's Local Score will be artificially low if all the best players are sitting in the same direction, as they have to compete with the other good pairs for the 7 or 8 matchpoints available in your room. Especially if your two best pairs are sitting in the same direction, you will often find both pairs see a big increase in their National Score -- with hundreds of matchpoints available, both pairs will be fairly rewarded for all their good boards.
On the other hand, if you sat in the same direction as all the weaker pairs in your club, you may have scored quite a few easy tops in your room for a big Local Score -- these may not hold up when your scores are matchpointed against 600 tables, and you won't have so many tops in your National Score.

it if the top pairs could send us a photo and biography for
our article in the October issue of Australian Bridge.
