The following chart converts from Starts to Odds for the favorite.





I am working on a calculator for roll-your owns and starts.

Is it too much trouble to get you to put the margins on the y axis,and the prices on the x axis.
Why?.I don't see the resemblance between this curve and your earlier one.

You went to all this trouble and then abandoned it.
Where are you Jakelee?

Hi Guys,

Been away... no internet for a week!

Anyhow, I have put together a website for NRL starts/Odds conversions.

The season's almost over though! But might be useful for next season.

I know jack ******** about NRL.
What data do you need for an AFL chart?

To do an AFL conversion (I already have the formula, just need the paramters). I don't follow AFL, so I'm not sure what range the starts go from (would you see a +80.5 handicap?):

I would need:

- Opening Fav/Dog Start and Opening Fav/Dog To Win Odds for quite a few values from equal favs (ie, +0.5) to a big difference (ie, +80.5). I also need the starting odds for the line (it's always 1.85 for NSW SportsTAB) Like this:

Line Odds: $1.85
Start Win Odds
-10.5 $1.70
-50.5 $1.21
+5.5 $2.00
... etc

I don't need every value, just enough so I can fill in the gaps.

If someone can provide this data for the TAB, I can calculate the

JL.

The most I've seen is +54.5. I doubt there has ever been anything over 60.

Jakelee.Is this any good?

Seems to be mistakes made by bookies,or more likely,minor differences due to who is playing who.

That's what I need. Give me a few days.

Come on Jakelee.
Just need the mathematical formula.
Margins to percentages.
No fancy webpage necessary.Something I could do on my calculator is fine.
