NRL Predictions for Round 18

Team Ratings for Round 18

Please note that I have treated most games as being played on neutral grounds, the exceptions being the Titans, Cowboys and Broncos home games. The NRL has announced that all clubs will be moved to Queensland and the games will be played at the same dates and times. However many of the games have their location still listed as TBA on the NRL website. I may have to issue an update later this week if the supposition of neutral grounds turns out to not be true. The most likely game where this might be the case is the Storm versus Knights game.

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

Currie Cup Predictions for Round 5

Team Ratings for Round 5

A note concerning treatment of cancelled games, or where a 0-0 score is allocated. I delete any cancelled games from my database, but also any games with an awarded result. That is because awarded result games will almost always cause an adjustment to my ratings which is not justifiable.
