United Rugby Championship Predictions for Week 1

Team Ratings for Week 1

A caveat regarding these predictions. This is a competition where four teams have been added, and there is little information about the performance of those new teams against the existing teams. There is also little information concerning the effect of travel when the new teams are in a different continent. I have used previous form from the Pro14, Rainbow Cup, Super Rugby, and Super Rugby Unlocked but have not been able to tune model parameters using years of past data in the way I usually do, nor obtain initial ratings to my satisfaction. Particularly early in the competition, results may be erratic.

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
Leinster 14.79 14.79 -0.00
Munster 10.69 10.69 0.00
Ulster 7.41 7.41 -0.00
Glasgow 3.69 3.69 0.00
Bulls 3.65 3.65 0.00
Edinburgh 2.90 2.90 0.00
Connacht 1.72 1.72 0.00
Ospreys 0.94 0.94 0.00
Stormers 0.00 0.00 -0.00
Sharks -0.07 -0.07 -0.00
Cardiff Rugby -0.11 -0.11 -0.00
Scarlets -0.77 -0.77 -0.00

Benetton -4.50 -4.50 -0.00
Dragons -6.92 -6.92 0.00

      Yes, all games predicted correctly. Likewise the French Top 14.

      However, randomness exists and in the same week I got less than half right in both the English Premiership and New Zealand NPC.
