Certified Legendary Thread The Squiggle is back in 2023 (and other analytics)

[gcsunsfc]

I might as well use this thread for the algorithm I've been running for two or three years now.

I'll start with the initial ratings for teams. This is an end-of-2017 form rating for each team. There's one conspicuous number which it's difficult to not notice, but if they're not as good as all that then the number will come down. There's also a positive skew at the moment, meaning that the average team rating is about 3. (It should, in theory, average out as zero).

1. Richmond 42.6
2. Adelaide 18.0
3. Sydney 9.5
4. GWS 6.9
5. Port Adelaide 3.0
6. Hawthorn 2.5
7. Geelong 2.3
8. Collingwood 1.8
9. West Coast 0.43
10. St Kilda 0.40
11. Melbourne -0.8
12. Western Bulldogs -1.6
13. North Melbourne -2.4
14. Essendon -3.9
15. Brisbane -4.0
16. Carlton -5.7
17. Fremantle -6.4
18. Gold Coast -10.2

This would make the first round tips (Yeah, I know it's been and gone, but it's an algorithm so it shouldn't matter)

Richmond +48 v Carlton
Essendon v Adelaide +16
St Kilda +10 v Brisbane
Port Adelaide +22 v Fremantle
Gold Coast v North Melbourne +2
Hawthorn +1 v Collingwood
GWS +14 v Western Bulldogs
Melbourne v Geelong +3
Sydney v West Coast +3

6/9 is probably about average. Margins could use work, except for my first exact margin of the year, with Geelong.

Round 2 ratings

1. Richmond +35.5
2. Sydney +22.6 (+1)
3. GWS +19.9 (+1)
4. Adelaide +11.5 (-2)
5. Hawthorn +10.6 (+1)
6. Geelong +9.8 (+1)
7. Port Adelaide +8.7 (-2)
8. St Kilda 2.5 (+2)
9. Essendon +1.7 (+5)
10. Melbourne -0.6 (+1)
11. Carlton -1.9 (+5)
12. West Coast -4.7 (-3)
13. Collingwood -5.7 (-5)
14. North Melbourne -9.0 (-1)
15. Brisbane -10.2
16. Gold Coast -10.3 (+2)
17. Western Bulldogs -13.9 (-5)
18. Fremantle -14.8 (-1)

Round 2 predictions

Adelaide v Richmond +18
North Melbourne v St Kilda +12
Carlton +14 v Gold Coast
Collingwood v GWS +20
Brisbane v Melbourne +4
Fremantle v Essendon +7
Western Bulldogs v West Coast +1
Sydney +23 v Port Adelaide
Geelong v Hawthorn +1

3/8 so far should dispel any thoughts that I'm taking advantage of doing the tips after the event. I'll post-mortem properly when the round is finished.

Hi, interesting stuff.
I've got questions about how GC rating went down after their first round victory.
Obviously attacking stats were poor (scoring shots, scoring efficiency etc..) but then in return defensive stats were excellent.

Do you mind sharing some of the variables used in your algorithm?

The algorithm sometimes moves in mysterious ways (as the weighting for old matches changes, for example) - in any case, a small home win against a weakish team doesn't count for much. However, if North's rating improves, so will the algorithm's respect for this win.

The algorithm is described in my old threads https://www.bigfooty.com/forum/threads/algorithm-revisited-after-finals-week-3.1160898/ and https://www.bigfooty.com/forum/threads/team-rating-system-update-after-finals-week-three.1128857/ .

North do a sharp turn in the right direction.

The thing about north is they’ve maintained excellent list demographics for many years now, never going to drop right off

I know I am a one-eyed supporter, but it amazes me to see the hate that comes North’s way.

It was the firrito led niggle which annoyed me, otherwise best of luck just not against us obviously

Squiggle currently predicting a 91-89 win to Hawthorn over Geelong in an elimination final. That game would be enormous. Sadly we get done by Richmond in week 2 of finals.

How does Richmond not drop ratings points when it misses your spread by 54 points????

Is recalculate not working again? Or just for me?

 

[WhiskeyTangoFoxtrot]

Early days still, but Adelaide, Sydney, Port, Richmond and GWS have separated into a clear top 5 so far.

Don't mind keeping a close eye on the squig.

This isn’t a discussion about the AFL ladder. It is a discussion about the Squiggle, which does not try and suggest that it represents the AFL ladder.

I know that, thank you very much. Just keeping things light hearted.

Which does lead to the question, how much of a streak does North have to get on before the squiggle (all hail to thee) takes us seriously?

Looking at the predictions for the next 3 North games, a couple of decent wins would likely put you level with Geelong and the Hawks and pushing into the space currently occupied by the top 5.

 

[Lions_Prid3]

Well round 2 is over and we are seeing two distinct groups form, oh, and my Lions doing their own thing out the back. The good news is that Carlton, the Bulldogs, and St Kilda all seem to be rushing over to hang out with us, so that's nice of them. That top 5 feels about right to me, but I do think Geelong and perhaps Melbourne, Essendon and god-forbid Hawthorn could jump over to the front pack as things play out.

Squiggle currently has Port and GWS battling it out for the flag, which is good I guess because it's nice to see fresh faces, and they both play scintillating football. It also means we all might be able to get a ticket to the big dance.

They went from +35 to +27. It just didn't cost them top spot.

Prob a three-peat.

[Lions_Prid3]

Round 3 was fairly tame in the way of squiggles, some good movement by Brisbane sees them join in with the main pack and now we see 2 very distinct groups forming - the top 5 & the rest. I suppose the question for the season is can anybody make the leap from the main pack to join the top echelon. I am reluctant to write off the Cats, as they have been so good for so long, but their injury list is currently an issue. For now, I will stay with the Demons to build form over the season and throw their name amongst the top contenders come seasons end. If that ends up being the top 6 then we should have a cracking finals series - 2 NSW teams, 2 SA teams, the reigning premiers (and arguably biggest club in the land), and the oldest football club coming in off a 12 year drought.

 

[LeverPuller]

Close squiggle week with Melbourne v Hawks being tipped as a 1pt game, opportunity for big movement for both sides
