Scoring Anomalies – Round 20

Written by The Salamander on August 8 2019

I haven’t made any major tweaks to the system this week, so it’s straight into the scores today.

As far as I am aware, nobody has enquired about any of the weekend’s score so far this week, so here are some that I found noteworthy.

First up, Shaun Higgins:

CD score: 140; SyntheticCoach: 170 (181 pre-scaling)

The breakdown makes the spread look even worse:

Shaun Higgins (North Melbourne)
• Effective kicks: 14 :: 56
• Effective handballs: 12 :: 18.0
• Clangers: 1 :: -4
• • of which frees-against: 0
• Ground-ball gets: 12 :: 54.0
• Goals: 2 :: 16
• Behinds: 0 :: 0
• Marks: 5 :: 10
• • of which contested: 0 :: 0
• • of which intercepts: 1 :: 2
• Tackles: 2 :: 8
• Frees-for: 3 :: 12
• Hitouts-to-advantage: 0 :: 0
• Goal assists: 2 :: 7.0
• Spoils: 1 :: 2
• Other one-percenters: 0 :: 0.0
Total: 181

Blindspots:
• Player had 7 clearances – perhaps some were gathered from a hitout (2 points each)?
• Player had 10 score involvements – perhaps this led to favourable scaling?
• SyntheticCoach knows nothing about when the game was on the line, let alone who did what when it was. This can have a massive effect on scaling.

Perhaps in future I should add a blindspot warning to the system for known burnmen: “Player may have burned somebody at CD one too many times.”?

GWS’ Zac Williams also looks to have been short-changed:

CD: 124; SyntheticCoach: 144 (167)

Once again, the blindspot warnings make the spread look worse rather than better:

Zac Williams (GWS Giants)
• Effective kicks: 13 :: 52
• Effective handballs: 10 :: 15.0
• Clangers: 2 :: -8
• • of which frees-against: 0
• Ground-ball gets: 12 :: 54.0
• Goals: 0 :: 0
• Behinds: 1 :: 1
• Marks: 10 :: 20
• • of which contested: 0 :: 0
• • of which intercepts: 0 :: 0
• Tackles: 6 :: 24
• Frees-for: 1 :: 4
• Hitouts-to-advantage: 0 :: 0
• Goal assists: 0 :: 0.0
• Spoils: 1 :: 2
• Other one-percenters: 2 :: 3.0
Total: 167

Blindspots:
• Player had 10 clearances – perhaps some were gathered from a hitout (2 points each)?
• Player had 6 score involvements – perhaps this led to favourable scaling?
• SyntheticCoach knows nothing about when the game was on the line, let alone who did what when it was. This can have a massive effect on scaling.

SyntheticCoach also thinks Sydney’s Hayden McLean (no, I’d never heard of him either) was short-changed, with CD giving him 76 compared to 93 (108).

Hayden McLean (Sydney Swans)
• Effective kicks: 3 :: 12
• Effective handballs: 5 :: 7.5
• Clangers: 4 :: -16
• • of which frees-against: 0
• Ground-ball gets: 6 :: 27.0
• Goals: 0 :: 0
• Behinds: 0 :: 0
• Marks: 4 :: 8
• • of which contested: 0 :: 0
• • of which intercepts: 0 :: 0
• Tackles: 5 :: 20
• Frees-for: 2 :: 8
• Hitouts-to-advantage: 6 :: 30
• Goal assists: 1 :: 3.5
• Spoils: 4 :: 8
• Other one-percenters: 0 :: 0.0
Total: 108

Blindspots:
• Player had 7 clearances – perhaps some were gathered from a hitout (2 points each)?
• SyntheticCoach knows nothing about when the game was on the line, let alone who did what when it was. This can have a massive effect on scaling.

It also thinks the same of Carlton’s Harry McKay:

CD: 87; SynetheticCoach 106 (116)

Harry McKay (Carlton)
• Effective kicks: 11 :: 44
• Effective handballs: 4 :: 6.0
• Clangers: 1 :: -4
• • of which frees-against: 0
• Ground-ball gets: 4 :: 18.0
• Goals: 1 :: 8
• Behinds: 2 :: 2
• Marks: 11 :: 22
• • of which contested: 2 :: 8
• • of which intercepts: 1 :: 2
• Tackles: 0 :: 0
• Frees-for: 2 :: 8
• Hitouts-to-advantage: 0 :: 0
• Goal assists: 0 :: 0.0
• Spoils: 1 :: 2
• Other one-percenters: 0 :: 0.0
Total: 116

Blindspots:
• Player had 7 score involvements – perhaps this led to favourable scaling?
• SyntheticCoach knows nothing about when the game was on the line, let alone who did what when it was. This can have a massive effect on scaling.

You’ll have to forgive the system for occasionally saying odd things like “… perhaps this led to favourable scaling?” when it is saying that a player was short-changed; at this point, the software doesn’t know what CD gave each player – I still have to compare its output with the official scores manually. This will be fixed eventually.



Anyway, were there any scores that seemed off to you on the weekend? Let me know in the comments, and I’ll let you know what SyntheticCoach has to say about it.

  1. Great again Sal. Zill’s dub-down annoys me a little.

    Do you share this with CD or FantasyFreako?

    Typo: Blindspot, not Bindspot 😉

    Thanks again. Awesome work

    1. Good pickup! Fixed.

      No, I haven’t shared this with CD/FF. I wonder what they would make of it?

        1. Cool, thanks!

          P.S. Champion Data/Fantasy Freako: please forgive my system’s crude assumption that non-spoil one-percenters (smothers, shepherds, and knock-ons) are all scored the same way (1.5 points each); with the granularity of data I have, there is no other option, unless I exclude the category entirely. For the record, if a player scores a significant number of points from this source, it triggers a blindspot warning.

        2. Aaaand we got a response: https://twitter.com/FantasyFreako/status/1159238802616905728

          | It’s a very simplistic way of looking at it.

          Geez, tough crowd!

          | Yes, there are basic points for each statistic, but there are many variables that go into a player’s score.

          We’re all aware of that. If this wasn’t the case, this column wouldn’t need to exist.

          | By the way, you don’t get any points for score involvements or clearances. You get points for your poss+disp in both instances.”

          I’m well aware that there are no points for clearances. But there are points for gathers-from-hitouts, a source from which many clearances no doubt emanate. It’s also a stat to which I do not have access. That’s why it triggers a blindspot warning.

          Also, does “no points for score involvements” also mean no *favourable scaling* for them, too?

  2. My buddy (Carlton supporter) swears Cripps broke even with Yeo in their match-up last Sunday. I disagreed stating Yeo was far more influential and won the match-up.
    Even after I pointed out CD backed up my assertion, he still would not be persuaded.
