Just looking ahead at the next round of tipping, and assuming all QF matches go to the higher seed (1-4), everyone will only have one of their 3 selections for the semis and final. No guarantee this will happen, especially seeing as two of the top 4 still haven't even made the QF yet, but it's quite possible, and theoretically is the most likely outcome. Seems a bit unusual that you might need to be relying on picking the best two QF losers to get a good score.
I'm happy to keep things as is, it would at least be a bit different, just throwing it out as a possibility you might not have considered (I'm sure you have).
3/3 for me today. For a tournament that looked like a tough one to call, I've surprised myself so far with 11/13 selections winning. Really did not expect that.
