Predictions for the Super Rugby Final

Team Ratings for the Super Rugby Final

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 this week’s games, along with the ratings at the start of the season.

Current Rating Rating at Season Start Difference
Crusaders 9.78 9.03 0.80
Sharks 4.43 4.57 -0.10
Chiefs 4.02 6.98 -3.00
Stormers 3.99 3.34 0.70
Bulls 3.94 2.55 1.40
Brumbies 3.07 -1.06 4.10
Waratahs 1.15 -4.10 5.30
Reds -0.70 0.46 -1.20
Cheetahs -1.16 -4.16 3.00
Hurricanes -2.28 4.40 -6.70
Blues -3.22 -3.02 -0.20
Highlanders -5.85 -3.41 -2.40
Force -7.69 -9.73 2.00
Rebels -8.66 -10.64 2.00
Kings -15.61 -10.00 -5.60

    Any chance of giving these posts their own topic/tag if they’re continued? Would make it a lot easier to find them than rather just filed under ‘General’.

    Also interesting to note The Chiefs rating has declined from 6.98 to 4.02 in spite of being in the final as the favourite.

    You had the right score for the Chiefs/Crusaders semi-final…just the wrong way round :( …(I’m a Crusaders supporter).
