Sorry about that. Lost track while travelling and forgot to give the Week 5 predictions. Weeks 5 and 6 posted now.

Hi David
I think the score on the hawkes bay v tasman score is incorrect and am assuming it would impact your model.
I look forward to seeing your model work each week and was out in NZ for 10 weeks.
Thanks

Thanks for the heads up.
A monumental stuff up on my behalf, unless they were wrong where I got them from. There were 3 wrong scores. I am currently having to enter results by hand rather than web scraping which is always likely to be error prone.
I have posted the updated predictions.
