Performance So Far

There is a problem with the code I have been using for assessing performance, due to the unusual schedule in the ITM Cup, where some teams play more than one game in a week. I haven’t had time to alter the code so am omitting this section for the time being. Look at last week’s post to see how the predictions went. For the record, there were 6 games correct, out of 8 games played last week

Predictions for the ITM Cup Finals

Here are the predictions for the ITM Cup Finals. 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.

Game Date Winner Prediction
1 Wellington vs. Counties Manukau Oct 18 Wellington 11.30
2 Canterbury vs. Auckland Oct 19 Canterbury 17.40
3 Tasman vs. Southland Oct 19 Tasman 17.90
4 Otago vs. Hawke’s Bay Oct 20 Otago 2.10
