Standard 11 rounds Swiss (like in Graz WCCC), >or the delayed Swiss as suggested by Gerd? Obviously there are some practical considerations, as Vincent pointed out. One problem might be the initial ranking (even in the lower part of the field), the other problem is whether a pairing program is able to handle such pairing restrictions during the first m of 11 rounds. Next problem is to determine the "optimal" m, the number of rounds with disjoint groups, to delay important matches - or whether it introduces more dependencies as suggested. And as already mentioned, all is dependent on the number of participants N. If N is 16, both groups are even (8) and there is no group internal "by". Then m == 7 is the maximum because it's already group internal round robin. If N is not divisable by four it becomes complicated, odd/even groups, one or two internal "by" (in case of two they may play each other as an other exception). Seems all too complicated and probably exhausting for the TD ;-) Anyway, thanks for considering the idea. I strongly consider to participate, independent on delayed or classical swiss system.
