When I have finished with a race , I end up with each animal having a Final rating.
I then use a formula that converts these ratings into a 100% Market , and it is based on the gap differences between the Ratings.

I've noticed in your Markets raven , that there is no correlation between the ratings derived in a race and the odds of that particular runner.

Like in Race 6

2 DI JAMAICA 90.8 90.8 $14.00
3 ARVO'S STEFAN 88.3 93.1 $14.00

Different ratings , different Averages but the same Price.
obviously your Market Price has a further factor built into the Formula , be it Box Position , Prizemoney won , or perhaps Strike rate.

Is that right , or did you make an error?

What I might try help you with , is if i see some glaring errors , I'll point them out to you , and perhaps there may be a factor which you may have to introduce to your calculations.

I'm not trying to put you down , but I don't know how much of a beginner you are , but in Greyhound races , Box 1 is immensely superior to Box 2 compared to Barrier 1 and Barrier 2 in horses.
And the Outside Box is often the next best Box after Box 1 , compared to the outside barrier in horse racing which is usually the worst.
Were you well aware of that raven , so I know where you at at in your knowledge?

And raven - what is the second Column labelled Rave in your Program?
I thought it stood for Race Average or maybe Rating Average , but a buddy of mine suggested it may be short for Raven?
