- Why projected Brownlow Medal vote counts are misleading
- Punters need to be focused on probabilities and price, like any betting market
Welcome to Part 3 of Brett’s Brownlow Breakdown. In the lead-up to Monday’s Brownlow Medal, Brett – the man behind our new Total Brownlow package – will share his key thoughts on betting on the Brownlow medal.
One thing I’ve noticed with all Brownlow Medal previews and predictions is that they all focus on ‘projected votes’. That seems to be what everybody wants to see.
We won’t be releasing vote projections. I think they’re actually somewhat misleading.
Yes, they’re a guide, but ultimately what’s important is a price. You need to create that price with your model.
Eyeballing vote projections won’t help you figure out a correct price. They can help you to establish a very simple trading policy, but that’s about it.
The importance of price
For example, in a head-to-head market… your projected vote count might have Player A two votes ahead of Player B.
But what does that mean price-wise? What price should each player be?
So a vote projection is not very useful for establishing whether a bet represents value or not.
Our approach is based on probabilities, just like any other pricing model.
We generate a probability of a player receiving either one, two three or zero votes in every game – they’re the four possibilities.
We do that for all 44 players, in all 198 games.
From there, simulations add all these player performance probabilities together. A player who played 22 games has 22 multinomial distributions for projected vote outcomes. They’re connected together and then it’s all iterated 5,000 times.
That’s the process we go through to come up with what we need: a price.
So our advice here is: put aside the vote projections and predictors for a moment. Knowing exactly how many votes a player will get isn’t the big question.
We’re betting here, so what’s important is the price, and whether that price offers value.
