Just to clarify- they are now using the Polish system which ironically has just been dropped !!!
3 QF matches( home and away) with the winners going into a table and the losers also into a table.
The 3 winners plus the best loser are in the SF’s.
2 winners meet in the grand final.
In the relegation play-offs the semi winners are safe and the 2 losers then face each other with the winner safe and the loser relegated( only 1 promoted from Div 2.
