Hi all,

Now that I am a little better from my health hiccup I wanted to try something a little bit different this season.

Does anyone remembers the Coventry Telegragh article about the Sky Sports predictor, "Elo"?

Coventry City's predicted promotion prospects

Its basically an old chess rating system.

Well, let's add some bells and whistles to it and update it a little.

The home page of Glicko-2 can be found here.

I certainly don't understand this but it is what the main chess servers use to rate the players that frequent there.

I've been having a late night look around the net and found a Glicko-2 calculator.

The ratings deviations doesn't show up on the website so I would recommend waiting until past the twelfth game for the RD to drop from 350 to 50. This is where there is confidence in the rating that it is in close proximity to the playing strength of the side.

This is all Public Domain stuff.

Glad you are a bit better.

Why risk your health though and come on to this plague-ridden place?

Yeah, but then you also get CC4L and Grendel too.

I'm also stating my intention to clear Nick out at the SBT Bookies!

 

[Philosoraptor]

Okay, I think today is a safe firm bet of twelve home wins, with an optional bet of correct score being 1-0.

With the idea of home advantage and the most common repeating score in the top four divisions in the football pyramid over the past hundred years or so.

Ditto what Otis said
Glad your health has picked up!

Cheers.

It should be interesting to watch the volatility in the ratings until they come out of provisional mode.

I have a cunning plan where I can watch the rating deviation, if the website has set it up correctly, and keep track of it for everyone.

Done something like this before. I was one of ones that cleared up the mess on a server caused by Steve Rosenberg.

Just to spice things up a little with the 'home and away' stuff in conjunction with ranking being a collection of both data sets cancelling the 'home and away' argument out over time.

When playing at home (white) I would usually assume that my rating is going to be higher, and my opponents rating (black) is lower then what is prescribed in the rating table, and visa versa for playing away from home.

The argument for this, I assume, has many branches both objective and subjective.

We have the same thing with chess when playing white or black.
