Personally I think fairest is Blacktown, Beecroft and Knox do keep their points (including Blacktown 2s results). As it stands they played games they won’t get anything for, and have to try to fit in an extra round of games (two for Blacktown) into 3 byes and a wet weather weekend while other teams get to rest players.
Though I guess if 4 teams are making finals, if this is the difference between making it and not you dont have much to complain about not making finals if you couldnt finish 4th out of 6 teams.
