Currie Cup Predictions for Round 5

Team Ratings for Round 5

The basic method is described on my Department home page. I have made some changes to the methodology this year, including shrinking the ratings between seasons.

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
Western Province 5.39 3.43 2.00
Sharks 3.32 5.09 -1.80
Lions 3.02 0.07 3.00
Cheetahs 0.25 0.33 -0.10
Blue Bulls -3.53 -0.74 -2.80
Pumas -7.10 -10.00 2.90
Griquas -8.55 -7.49 -1.10
Kings -12.12 -10.00 -2.10

 

Performance So Far

So far there have been 16 matches played, 14 of which were correctly predicted, a success rate of 87.5%.

Here are the predictions for last week’s games.

Game Date Score Prediction Correct
1 Pumas vs. Sharks Aug 29 32 – 22 -7.50 FALSE
