| Hurricanes | 8.31 | 2.89 | 5.40 |
| Waratahs | 7.48 | 10.00 | -2.50 |

Shouldn’t the Waratahs be at home? Would the home ground advantage change the prediction?

Sorry I see it’s already corrected on the site.

Interested in how the current Team rating table works in respect to the Crusaders still having a clear margin at the top but not featuring in the Semi Finals…

NRL performance so far into 2015 Season after 110 games played:
55 home team wins, 55 away team wins. How curiously extraordinary!
Predictions in this space number 62 true, and 48 false — or 56.3 per cent true.
Do teeter-totter results improve the Code in the long run, by promoting more excitement around the grounds, as NRL commentators are saying? We’ve certainly witnessed remarkable club upset wins, together with spectacular individual artistry
taken to new heights.
