in practice it's actually a lot less trouble than what it sounds like. instead of having to be better than 1 team on 1 day, you have to be better than the whole group cumulatively. that was an embarrassing tournament formatting error. the guy who came up with that is a known idiot. then again it's also bwf's fault for not vetting the format thoroughly... which contained obvious scenario's of tanking. this final grouping does not reward tanking because you can't avoid a certain team. you have to play every team in the final group.
