Cobra told you that at least 7 people qualify. So, do the math yourself to figure out how many points are needed for that.
At least 7, but what's the maximum? Well, I guess I can figure that out.
Right now, four people already have 21+ points (Buvli, Antiplayer, and two more will rise from the pairs, who currently have 18). Another 10 people (5 pairs) will play against each other in the last round, all having 18+. Five of them will win, meaning at least 5 more people will have 21+ points at the end of the tournament. In total, 4+5=9 people will have 21+ points at the end of the tournament. They are out of reach for those who have 15 points after 8 rounds (including me).
Plus, due to early losses, my rating is not good, and among those who finish the tournament with 18 points, there will be at least 5 more people with a higher rating. And hoping that they won't be there because they will withdraw (because, like me, they have no chance) is pointless - these will be the same 5 people who will lose in the pairs in the last round with 18+ - and they will not withdraw, because they still maintain a chance of qualifying for the Final Battle until the very end.
In total, we already have 14-15 people who will definitely be above me at the end of the tournament. This is already known at the moment. There is no mystery here. And no guarantees are needed from anyone.
Is there a chance to qualify for the Final Battle from 15th place?
