Predictions for Round 13
Here are the predictions for Round 13. The prediction is my estimated expected points difference with a positive margin being a win to the home team, and a negative margin a win to the away team.
The Cheetahs have been playing in the Pro 14 competition and fielding a second or third team in the Currie Cup. They have another such game this weekend causing problems with prediction. After 4 such games a quick estimate is that they might score 27 points less than if they were fielding their best team, but losses so far will have dropped their rating a couple of points already. I would guess that a difference of 25 points might be appropriate, so instead of the points difference being 6.1 below, it might be -19 and a win to the Blue Bulls.
Game | Date | Winner | Prediction | |
---|---|---|---|---|
1 | Cheetahs vs. Blue Bulls | Oct 06 | Cheetahs | 6.10 |
2 | Griquas vs. Pumas | Oct 07 | Griquas | 0.90 |
3 | Lions vs. Western Province | Oct 08 | Lions | 3.00 |
