Super 15 Predictions, Round 19

Team Ratings for Round 19

This year the predictions have been slightly changed with the help of a student, Joshua Dale. The home ground advantage now is different when both teams are from the same country to when the teams are from different countries. The basic method is described on my Department home page.

Here are the team ratings prior to Round 19, along with the ratings at the start of the season.

Crusaders 7.56 9.03 -1.50
Bulls 6.64 2.55 4.10
