For how many times a board is played that the board will not be played again in duplicate IMP/MP? Or is it a time limit?

The result window show 16 tables at most

In the main room, each board is played 16 times. That is it.

In tourneys, it depends upon the number of tables. In a 147 table tournement, each hand will be played 147 times.

Is there time limit also?

I never see others playing the same board that I have just played?

..This means that if you have played a board on BBO, then after fi 5 minutes nobody else will play it anymore? (and no issue to immediatly post it here with questions)?

Yes ...

After playing some hands and go to kibitz other tables, it seems that I never see the hands that I have just played?

The time between the first pair that plays a hand in the main room and the last pair that plays the hand averages around 5 to 7 minutes. At times when there are a lot fewer tables in play, this time is stretched out a bit. I have seen 14 to 18 minutes in the past.

You can check this yourself by looking at the traveller for any completed hand. The first time shown is the local time when the hand was "Saved" (aka complted). A typical list would look like this...

19:48
19:48
19:46
19:48
19:47
19:45
19:46
19:46
19:46
19:43
19:46
19:47
19:45
19:47
19:44
19:43

As you can see this is a five minute range from 19:43 to 19:48.

When BBO had 200 players on line and 25 tables in play, playing a board only 16 times made some sense.

With 5,000 frequently on line, does it still make sense to only play a board 16 times?

Tournaments attempt to score a board over several sections. Before, in a large event you were competeting only against your section. As technology has improved, national events are usually scored over a 4 sections, to make the scores more reflective of the the whole. I suppose there is a practical limit to this, I can foresee the conversation, "Hey - what did you get on #8...only a 1352....oh too bad, 5,000 is a TOP".

Maybe its a statistical fallacy, but it seems to me that the aberrant result you see every few hands (-2800 in 7N xx'd for instance) that creates an unfair swing to the field would flatten itself out over say 50 or 100 boards.

Seems the programming would be rather simple too. Maybe BBO could try it for a month and see if it makes the scores more equitable.

What is done about Matchpoint boards in the Main Bridge Club? Are these ever indexed against small tournaments? Sometimes there are very few MP tables so getting 16 plays could take quite some time.
