Six double-ups each

FS-03

What it means

Each club plays six opponents a second time. The number is set each season; it has been six since 2023.

Twenty-three games per club needs six more than the seventeen that playing everyone once provides.

Carlton plays 17 clubs once and six of them twice.

Must-follow The fixture must obey this rule. A separate checker tests the finished fixture afterwards.

Must-follow. The number six is a season setting, not a permanent fact.

How the fixture is made shows how this plays out across the season.

One cell per release, oldest first. Each shows the verdict that release recorded for this rule; a release with no row for the rule says so.
