AFLW 2025 - Round 15 Results - Regression Free

/

WoSHBODS and the two bookmakers tipped both winners this week.

WoSHBODS also recorded a Margin MAE of 16.2 points per game (compared to 21 and 20.6 for the bookmakers) and a Totals MAE of just 3.3 points per game (compared to 8.2 points per game and 8.0 for the two bookmakers).

The LPS of +1.6 bits compares to +1.3 bits for the two bookmakers.

It’s truly been about as good a performance from WoSHBODS as I could have hoped for.

Overall, it’s now at 72% accuracy for the season, 22.3 Game Margin MAE, 16.2 Totals MAE, and +26.9 LPS.

AFLW 2025 - Round 13 - Unders/Overs

/

UpDATE 10:35AM SUNDAY

Sportsbet has now posted markets for the two games today, including a line of 81.5 for the Adelaide v St Kilda game. WoSHBODS has therefore topped up its unders wager by now adding:

  • Adelaide v St Kilda: 0.6% u81.5 @ $1.85

The forecast rain is keeping us out of the market in the Melbourne v Brisbane game.

UpDATE 3PM SATURDAY

WoSHBODS has taken:

  • Adelaide v St Kilda: 0.2% u79.5 @ $1.87

It passed on overs bets on North Melbourne v Hawthorn yesterday, and Carlton v West Coast today because of forecast rain. Currently, the line for the latter game is 52.5 points, which represents an estimated overlay of 27 points according to WoSHBODS’ number. That would have justified an 8% wager. I can only assume that it is - and probably has been - raining heavily in Melbourne.

Note that Sportsbet has no Totals markets up for today’s or tomorrow’s games, and TAB has none up for Melbourne v Brisbane tomorrow.

AFLW 2025 - Round 13 - Week 1 of the Finals

/

According to the bookmakers, the first week of the AFLW Finals comprises:

  • Two games expected to be decided by less than two goals

  • One game expected to be decided by between two and three goals

  • One game expected to be decided by about six-and-a-half goals

Below are WoSHBODS’ thoughts about the four games of the round, which sees three favourites winning, all of them by a larger margin than forecast by the bookmakers. The one forecast underdog winner is Melbourne (over Brisbane) and they are forecast to win by less than a point.

The TAB bookmaker’s average expected victory margin is about 16.8 points per game, while WoSHBODS’ is about 20.4 points per game.

AFLW 2025 - Simulations After Round 11

/

This year’s post Round 11 simulations suggest that the teams - in terms of their home and away season finishes - can be roughly grouped as below:

For anyone who is curious about the precise methodology I’ve employed, see this blog post over on the General Probability and Statistics journal

  1. North Melbourne: virtually certain Minor Premiers

  2. Hawthorn, Brisbane and Melbourne: certain of being finalists

  3. Carlton: 95% chance of finals

  4. St Kilda: 85% chance of finals

  5. Sydney: 75% chance of finals

  6. West Coast: 60% chance of finals

  7. Adelaide: 50% chance of finals

  8. Fremantle: 30% chance of finals

  9. Port Adelaide, Geelong, Western Bulldogs, Essendon, Collingwood, Richmond, GWS, and Gold Coast: No chance of finals (Port Adelaide and Geelong are mathematical chances, but Port Adelaide finished 8th in just 3 simulation replicates, and Geelong in none)
