Me neither. I guess it implies somehow the dead body rule, but no idea.
After 6 days, I think we had enough bouts to do a bit of talk. Some good sumo today, including, as commented above, that last second kotenage that Mitoryu pulled, and the lively combat between Okinoumi and Azumaryu, two vets that still had something left in the tank. No idea where's Ura's mind this days, but his two meters approach from the shikiri sen it's not working anymore, at least when you combine it with nothing else. Wakatakakage with not the best record, but fighting well, and still pointing at himself as the next ozeki hope, in my opinion. Hoshoryu is doing great, too, fast, serious, and pulling (intentionally or not) some great techniques, like that beautiful kawazugake on day 5th. Mitakeumi looking strong and calm enough to regain his Ozeki rank, although is too soon to tell. Shoday more awake than usual in the first week, could mantain his Ozekiness again, and Takakeisho will get his own kachikosi easily, but not so sure he will fight for the Emperor's Cup. Tamawashi maybe celebrated in excess his Aki yusho, or just don't want to force himself too much at his age, no idea. And to end this comment, my favourite Takayasu, once again fighting well, and having fought already the top guys from the banzuke, with just one loss handled by his nemesis Shodai. The problem may be, again, his "not programmed" losses again folks he should dominate. So let's see how he manages this time.
