Pro 14 Rainbow Cup Predictions for Round 4

By

Team Ratings for Round 4

These predictions come with a caveat. I have done them mainly with a view to updating my ratings for the Pro 14 teams and in particular the South African Super Rugby teams. Having done them, I thought I might as well publish them from now on. The initial ratings are derived from the end of the Pro 14 and Super Rugby Unlocked competitions. Even though there are really two separate competitions it is convenient to lump them together because that is how the fixtures and results are available on the internet.

The basic method is described on my Department home page.

Super Rugby Predictions for Week 13

By

Team Ratings for Week 13

Just a note concerning the ratings this week. There have been no games between Australian and New Zealand sides since early in 2020. The ratings below started off from the ratings after the last of those games and have been updated based on games in Super Rugby Aotearoa and Super Rugby Australia in 2020 and 2021. Caution is needed about the ratings for this next series of Super Rugby games because of this ratings history. I chose not to shrink the previous ratings before the start of this series of games which is something I usually do to a minor extent between seasons.
