We unpack the Result Scores from the IAAF World Rankings for the recent Queensland International Track Classic. Statistically, what was the performance of the meet?
The purpose of this analysis is to assist with familiarity around Result Scores, based on the IAAF Scoring Tables, which are a key element of the IAAF's new World Rankings. These rankings become relevant next year for Olympic qualification for approximately half of the field in each event, which we've explained in this recent blog post.
Given the focus of the article on Olympic qualifying, we've excluded from the below analysis performances in events where this wouldn't be relevant... so as fine a performance as they were, Dane Bird-Smith's 11:01.32 3000m walk (1180 points), Katie Hayward's 12:10.17 (1144 points) or the Australian 4x100m (38.83s, 1162 points) or 4x400m (3:03.63, 1136 points) won't feature further in this piece.
What's the headline grab? What were the top male and female performance?
Yoshihide Kiryu and Rohan Browning both ran 10.08 seconds in the 100m, which tops the men's performances with 1179 points.
Brooke Stratton's 6.74m long jump was the top women's performance, worth 1160 points.

How would performances of this quality contribute next year to Olympic qualification?
These performances - and many others not listed - are combined with a Placing Score for the meet to contribute to a Performance Score. Generally, the average of an athlete's top 5 Performance Scores determines their Rankings Score.
The Queensland International Track Classic is ranked by the IAAF as a 'Category B' meet, which is the highest category that is annually held in Australia. The Placing Scores obtained are:
1st - 100 points
2nd - 80 points
3rd - 70 points
4th - 60 points
and so on for the top eight places.
As a 'suck it and see' rule of thumb, we'd suggest an athlete would be unlikely to miss Olympic selection if they have a Ranking Score of 1200 points. IAAF modelling suggests a lower Ranking Score than this in every event, but that is prior to the new qualifying process being put in place, and athlete behaviour will likely change accordingly.
So for context, most of the performances in the 'Top 10' list above would be worth more than 1200 points when the Result Score and Placing Score are combined. As just two examples:
Rohan Browning: 1259 points (1179 Result Score and 80 Placing Score for second place)
Jack Hale: 1212 points (1142 Result Score and 70 Placing Score for third place)
We use this example to show the importance of the placing and category of the meet, especially when also comparing Hale's 10.20 second run (only 0.01s slower) when winning in Perth (which is a 'Category C' meet - where only 60 Placing Score points are on offer for the win):
Queensland Track Classic, 1212 points for 10.19s performance for third place
Perth Track Classic, 1198 points for 10.20s (1138 points) for the win (60 points)
The takeaway from all of this - and what the IAAF World Rankings seek to promote - put in your best performances at the most valuable meets.
