I think there is a bug in calculation of OE tax in playoffs. Here is the situation for one of the clubs in Turkey:
http://tinypic.com/view.php?pic=148nr00&s=8#.UzGSuYW0...In the last home game he had an income of 268k. Last week he had 2 away playoff games, for which he gained 163+145=308k. however in the OE tax calculations, the home income from two weeks ago was used (268k), not the total income he actually got that week (308k).
