I don't see why groups can't just be 100% random. It's easier and leaves everything up to chance. All this system really does is guarantee, with a fairer certainty, that the lowest ranked films from round 1 will be eliminated in round 2. Looking at the above poll, this is quite clear. The results in this poll literally go from highest percentage of Rd 1 votes to lowest percentage of Rd 2 votes. It's fundamentally flawed in that respect.
