This is a tool that predicts the results in the 2011 Rugby World Cup, based on the specified importance of the various prediction factors, which are listed below:

• The importance of the IRB (International Rugby Board) world rankings, on a scale of 0 to 10.
• The importance of results in all the previous World Cups, on a scale of 0 to 10.
• The importance of home advantage, on a scale of 0 to 10.

If any of the prediction factors is set to 0, it will be ignored when making the predictions. Therefore, if all the prediction factors are set to 0, the predicted results will be completely random.
