Analyzer helps you to generate overall/seasonal rankings tables which looks according to the scores you set here. Remember: system logic doesn't watch when the games took place and their orders - only the points themselves, so you can see their summed scores in the cells:
In this matrix the scores showed twice, like that black rectangles were a mirror - which is logic, since "A 2-0 B" is also "B 0-2 A".
If you click on a cell, a new dialog will appear, and you can set the new score here. Already modified cells became pink coloured. If you're finished, press "Calculate new points!" button, and wait until the ranking table is being calculating.
