I was hoping to be able to release predictions in batches of 8 matches, but some matches which could be predicted already would then not have a prediction. Instead I have decided to predict all future games, and update as required to ensure that before a team plays, my predictions will take into account all previous games.
Observe below that means for example that I will provide updated predictions before the Georgia vs. Uruguay game to take into account the game played by Uruguay against Fiji.
