My partner and I played tournament "#2675 Speedball Pairs (IMP/Swiss)" and I thought the movement was a bit odd.

There were four pairs, two full tables.

Round 1, we played pair "A", boards 1 & 2.
Round 2, we played pair "B", boards 3 & 4.
Rounds 3, 4, 5, 6, we played pair "C", boards 5-12.

This doesn't seem quite right; shouldn't the movement have had us play each of the three other pairs for four boards?
If not, how were the pairings determined?

Swiss like, this is, best score plays 2nd best, 3rd plays 4th, (etc.)

Now, a Swiss as I understood it does avoid repetitions as far as it is possible, but "BBO Swiss" does not.

Not much to pick from 4 pairs anyway.

I guess it's possible that pair "C" the top two places with us for each of the last four rounds.
It would seem a bit unusual, though!

Unusual, but it actually happened in this case. The standings, after each round, were:
Rnd.....You.....A.....B.....C
..1........-8.......8......-8.....8
..2.........8......-8.....-24....24
..3.........1.....-15.....-17....31
..4........-1.....-17.....-15....33
..5.........4.....-22.....-10....28
..6........18.....-36.......4....14
Once you and Pair C had the big Round 2, you two were always ranked ahead of A and B.

That's a nice table.
I know I'd enjoy the chance to see that for the results in all the matches
(it would get pretty complicated to do when the player count gets up into the
40s or hundreds, as it does for some tournaments).

Is there any functionality to generate this in BBO?
