Independently of the fix you gave at http://rt.cpan.org/Public/Bug/Display.html?id=29486 (bug report about downfloaters not being recognized correctely), I have a second problem with the same pairingtable: Round 5 Pairing Groups ------------------------------------------------------------------------- Place No Opponents Roles Float Score 1 8 18,5,3,1 BWBW D 3.5 2 1 11,10,6,8 WBWB U 3 3-9 2 12,7,9,5 BWBW 2.5 4 14,9,7,17 BWBW 2.5 5 15,8,13,2 WBWB 2.5 7 17,2,4,9 WBWB 2.5 9 19,4,2,7 WBWW 2.5 16 6,19,11,10 WBWB 2.5 17 7,14,18,4 BWBB d 2.5 10-14 3 13,6,8,11 WBWB u 2 6 16,3,1,15 BWBW 2 11 1,12,16,3 BWBW 2 13 3,18,5,19 BWBW 2 15 5,20,10,6 BWWB 2 15-16 10 20,1,15,16 BWBW 1.5 20 10,15,14,12 WBBW D 1.5 17-19 12 2,11,19,20 WBWB dU 1 18 8,13,17,14 WBWW u 1 19 9,16,12,13 BWBB u 1 20 14 4,17,20,18 WBWB 0 Trying to get pairings for round 5, pair (and pairstately) returns the following error message: Show quoted text

I guess, there is a bug somewhere? Does it help if I post the files I used? Best regards Christian

I can confirm this. With the fix applied, there where no errors and I got my pairings for round 5. Thanks Christian

I should have provided a more precise fix. I am including a test based on this pairing table in 0.09 because it exercises the code for C10. I hope the pairings here are correct.

A fix that I have in the works for the problems in 0.09 is breaking the test for this bug. 20 and 12 are being swapped in the 3rd- and 2nd-last brackets. To get the fix out the door, I am changing the test. Hey-hey. If it can be shown that the 0.08 pairing of the test is correct, ie, that 20 should be on the second-last table and paired with 18, and that 12 should be on the 3rd last table and paired with 10, I will change the test back.

I don't understand, what you mean by "20 and 12 being swapped". You don't speak about an exchange between S1 and S2, do you? Show quoted text

I think that the 0.08 pairing is the correct one. But it comes down to the discussion about waiving of B5, B6 for upfloats, doesn't it? The relevant part of the pairing table: 15-16 10 20,1,15,16 BWBW 1.5 20 10,15,14,12 WBBW D 1.5 17-19 12 2,11,19,20 WBWB dU 1 18 8,13,17,14 WBWW u 1 19 9,16,12,13 BWBB u 1 20 14 4,17,20,18 WBWB 0 If we waive B6,B5 for upfloats (for players 12,18,19), then 10-12 and 20-18 look okay. (20-19 would be even better because auf B4, but then in the next score bracket 18-14 is not possible, therefore according to C12 one should end with 20-18). If we don't waive B6,B5 for upfloats 10-12 and 20-18 are not okay.

Yes, of course. Actually I thought about suggesting that, but somehow forgot about it.

No need to discuss this. Games::Tournament::Swiss r 1455 now agrees that your analysis is correct.

Just for the records (or in case someone else reads this): I asked about the correct pairing at http://chesschat.org/showthread.php?t=6925 (post no. 15, last post on first page). Unfortunately I didn't include enough informations (for instance I forgot about round 5 being the last round; maybe my fault was to include to much information, namely the upper part of the pairing table?) and as a result I exacerbated one of the experienced arbiters around. Alas, there has been no complete answer to my question how the last boards should be paired. But there was one post (http://chesschat.org/showpost.php?p=170418&postcount=29) saying, that my suggestion (12-10, 20-18, 19-14), was not the correct pairing. Unfortunately this is the choice of Games::Tournament::Swiss (0.10) as well. So it's quite possible that there still is some trouble left with version 0.10. Best regards Christian
