Our sister site Australia Sports Tipping has published a winning margins frequency tool. It is available for the following leagues:
The tool enables you to view winning margin frequencies for the selected league. Average and median margins are also calculated. You can select the specific time-frame for the data to discern changes over time. You can also change the points increment for the margins.
The tool also enables you to view the distribution of winning and losing margins for a specific team, both home and/or away.
Below is a screenshot of the home and away output for Sydney FC based on 2009-2021 data.
