Just thought I'd post this in case it's of any use to personal odds line users who haven't considered "grading" there bets. I think you get the same sort of idea from Barry M. (I think he bases it on kelly).
Anyway, 10 years back, one of our biggest bookies (Mark Read) launched his product, "Read's Ratings." These give you the contenders in each race with the rated odds. Average of 4 per race. Sometimes 5 (esp. big fields). Sometimes 3 (esp. short fields). You get them either by subscription, or free from a betting outlet that subscribes, which several do.
Profits made from the launch were donated to a charity. Can't remember exactly how much - but I think it was something like $30,000.
The starting bank was $50,000 and the units were $100.
There was a scale of "base uinits" according to rated price, which follows:
< 2/1 10.0
=2/1 9.0
9/4 to 5/2 8.0
11/4 to 3/1 7.5
13/4 to 7/2 7.0
15/4 to 4/1 6.5
4/1 to 5/1 6.0
11/2 to 6/1 5.5
13/2 to 8/1 5.0
9/1 to 10/1 4.5
over 10/1 4.0
(sorry if the table comes out bad!).
The formula used to determine a bet was simply: "available odds" divided by "rated odds" multiplied by "base units".
Example: Redelva had a rated price of 5/4 and an available price of 2/1
2/1 divided by 5/4 = 1.6
Look up the table and you see that 5/4 has 10 base units.
1.6 * 10 = 16
If you remember, units were $100, so the bet on Redelva was $1600.
As you can see, very kelly, but it might be of use to someone!

PS. Did you know you can now bet US racing on the x-change?
