you've got to assign the 9 double ups for each team for each year, so each team has a year A fixture and a year B fixture, but how do you do that? If you try and make them as equal as possible now, it's extremely likely that in 5 years, you may have an extremely unequal fixturing example like this
-Hawks year B assignment is playing GC, Melbourne, Saints, Dogs, Geelong, Freo, North, Port and GWS. Say we're in 2026 and that's 6 bottom 10 teams, and only 2 top 8 teams that Hawks are doubled up on, giving them an extremely easy fixture. 16/25 games against Bottom 10 teams
-Cats year B assignment is playing Hawks, Bombers, Collingwood, West Coast, Brisbane, Adelaide, Saints and Swans. In 2026 this could be 6 top 8 teams and only 2 bottom 8 teams that the cats are doubled up on, giving them a super hard fixture. 11/25 games against Bottom 10 teams
You either have the year A/B fixture style or you try to make the comp equal by putting in the FIX.
