Number of rounds
I know the reference seems to suggest that there were six rounds of Swiss, but I'm not so sure. 183 people participated, but six rounds of Swiss is only enough for 2^6 = 64 people. A Swiss tournament would really need eight rounds if there are between 129 and 256 players. The IP, used by the person who tried changing it to eight, is located somewhere in the Netherlands, so it could have been by someone who was at the tournament. -- Deltaneos (talk) 20:21, June 23, 2012 (UTC)
- Maybe, but I just changed it back after I read this. Dunkles Magiermädchen (talk • contribs) 20:52, June 23, 2012 (UTC)
- That page is dated May 2, while this tournament, the nationals, took place June 9–10. The May 2 one seems to be a regional.
- I think I was just being too presumptuous earlier and assumed no coverage between Round 6 and the elimination stage meant there were no rounds in between. -- Deltaneos (talk) 21:28, June 23, 2012 (UTC)
- Sorry, I didn't check the date before but I asked him/her. Dunkles Magiermädchen (talk • contribs) 19:08, June 24, 2012 (UTC)
- According to the Nationals FAQ here there are six rounds for 33-64 people, seven rounds for 65-128 and eight rounds for 129-256 (there's a table at the top of page 3). Dunkles Magiermädchen (talk • contribs) 12:48, July 4, 2012 (UTC)
- Yeah, it's how Swiss tournaments work in general. 2^(number of rounds) should be just enough to cover the number of players. e.g. 7 rounds is enough to cover 2^7 = 2×2×2×2×2×2×2 = 128, 8 rounds is enough to cover 2^8 = 2×2×2×2×2×2×2×2 = 256. If you use less rounds it's possible for someone who isn't the best player to win because they got easier opponents.
- I think we can safely change the number of Swiss rounds to 8. -- Deltaneos (talk) 19:11, July 4, 2012 (UTC)
