McIntyre system
The McIntyre system, or systems as there have been five of them, is a playoff system that gives an advantage to teams or competitors qualifying higher, by allowing higher qualified teams to lose more games or series before being eliminated compared to lower qualified teams. The systems, which include four-team, five-team, six-team and eight-team variants, were developed by Australian lawyer, historian and English lecturer Ken McIntyre, with the first system developed for the Victorian Football League in 1931.
The four-team and five-team variants in particular are widely used in Australian sports, and the four-team variant – also known as the Page playoff system – enjoys some wider use globally.
