First rounds will always have 7-16 matches to predict, it's still tipping the winners and not the same thing as finals.
It's still having your fate decided by PTS before any other options are used. It still sucks. Thank god you aren't having us predict all the first round matches, although I wouldn't be surprised. TT Managers should combine with PTS and just make one game.
I don't know what would be so awful about using set ratios ahead of your 5 tiebreaks so that PTS is the LAST option. The first time someone STILL loses by ranking even with 5 tbs, they will whine and whine and you'll just have us predict them all.
