Scoring Anomalies – Round 13

Written by The Salamander on June 18 2021

This week, I’m going to do much the same as last week, but with two scores from Round 13. For this, I’ve picked out Collingwood’s Brayden Maynard and Jamie Elliot from the above chart.

For reference, here’s how the game went:

Once again, I’ve added up the time-series-based score by hand this week. They’re still slightly different from the SyntheticCoach raw scores (Maynard was 188 instead of 188.5, and Elliot added up to 80 instead of 78). I’m not actually sure which one of these is more accurate, but they’re close enough for what we’re trying to accomplish here today.

Based on the unweighted scores, the multiplier for the game was approximately 0.826, meaning we need to get Elliot’s weighted raw score up from 80 to around 97, and Maynard’s down from 188 to about 172.

One thing that I noticed early on was that the third quarter was Elliot’s busiest, and Maynard’s quietest, so that seemed like an appropriate place to start.

It also occurred to me that CD would probably want to keep the average weighting for the game at 1, so I’ve tried to do the same.

The highest weighting I went to for a quarter last week was 1.75, so I started there this week. I bumped the other three quarters down to 0.75 to get the aforementioned average to 1. Here’s how it went:

Q1: 0.75 Q2: 0.75 Q3: 1.75 Q4: 0.75

Elliot: 93, Maynard: 174.5

For a first guess, that’s got me pretty close to where I needed to be. Pushing it a little further:

Q1: 0.66 Q2: 0.66 Q3: 2 Q4: 0.66

Elliot: 97, Maynard: 169

Elliot’s score is bang-on, and Maynard is only 3 points off. Given that the true multiplier is unknown (I would need all the weighted raw scores from the game in order to calculate it), we can probably stop at this point, and say “close enough.”

That went a bit quicker than I was expecting!

For comparison, I also tried to infer some weightings from the live scores on the day (thanks to Lock and Load for suggesting this idea, and to Lisa for for posting quarter-by-quarter score updates in that match’s Game Chat thread.) By comparing the proportions of change in actual score and change in raw score, divided by the multiplier to try and account for in-game scaling, I was able to get weightings of 0.98 for the first half, 1.19 for the third quarter, and 0.61 for the last quarter (though the weighting for the last quarter was based on the final, post-game, post-weighting scores, so that may not be totally accurate). This actually gets Maynard right to where we need him at 172, but doesn’t get Elliot anywhere near 97, leaving him in the mid-70s.

In practice, the final weightings are not determined by Champion Data until after the game has finished, so it’s probably not really possible to infer the actual weightings from the live scores.

The biggest thing I’ve learned in the last two weeks of doing this is that CD seems to weight different periods of the game far more aggressively than I had originally assumed.

This doesn’t necessarily get me much closer to the aim of being able to have a machine look at the score worm and determine the appropriate weightings, but I do at least have a clearer idea of what those weightings will tend to look like. The caveat here is that we have a sample size of just two games for that, so I will need to keep investigating that further in the coming weeks.

In the meantime, you can look up any player you like in the table below to see how their score was affected by scaling on the weekend; for an in-depth breakdown of their scoring, see the spreadsheets attached at the bottom of this post.

The exception to the above this week is Hawthorn’s Jai Newcombe. I haven’t added the mid-season draftees to the bit of SyntheticCoach that lets me get each player’s real score into the table; I’d got away with it up until now, because none of them had played until the weekend. I’ll get that fixed up for next week.

LEGEND:

Raw: SuperCoach points, added up according to the formula put out by Champion Data, before any scaling.

Linear-Scaled: Raw points, multiplied by a multiplier (3300 / total raw points for the match) to get the scores in each game to add up to 3300.

Actual: Actual SuperCoach points, as awarded by Champion Data.

Diff: Difference between actual and linear-scaled points. In practice, this is how favourably or unfavourably a player was scaled – this is ultimately what I’m setting out to investigate.

  1. Interesting, I have Kelly, Steele and O’Brien. Lost 56 points!
    Pretty good how you work this out.
