Team Ratings for Week 6

I have just updated the prediction for the Force vs Brumbies which is to be played in Perth. The locations of the games between these two teams were swapped around because of the difficulty of travel to WA.

NRL Predictions for Round 3

Team Ratings for Round 3

Unfortunately I entered my updating parameter incorrectly when preparing the predictions for the NRL, which I only realised when looking over the predictions for this round. I misplaced the decimal point so the parameter was out by a factor of 10. The predictions for Round 1 were not affected but those for Round 2 are. The updated values for those predictions are below. If you check the posted predictions for Round 2 you will see that there were extreme changes in the ratings from Round 1 to Round 2, which should not happen.
