      Thanks very much for the correction. I always appreciate being notified when I have details wrong. It is quite difficult at the moment with so many changes and I have to do a lot of data entry by hand rather than use programs to drag information from websites to update fixtures and results.

      I have updated the forecast for that game.

      Thanks for the advice. My match dates are New Zealand time, and I have the games on the 24th at 1am and 3:30am New Zealand time. Using New Zealand time is a function of how I obtain the data and it would be a pain to change to local times. Note that this applies to all competitions which I forecast.

      As I said before though, I welcome comments and corrections, and I do thank you for pointing this out.
