How are the bullets on the ARIA chart determined?
The bullets attached to both the ARIA Singles and Albums charts are determined by upward chart movement over the previous week. The number of places that a title needs to move to qualify for a bullet is less towards the top of the chart. It is more difficult to move up five places in the top 10 than it is to move 20 at the lower end of the top 50. Titles do not qualify for bullets below position 70 on the chart.
