Dolly,

They use weight and time ratings but also supposedly info received from stables etc.
Not sure how you convert this to kgs?
Anyway, each horse is rated to 0.1 kg accuracy and then those within 5kg of top rated are priced to to an 85% market.
Not exactly sure how the ratings are converted to prices but some analysis shows that it fits a negative exponential curve.
eg decimal = exponential (-0.2*margin from top)

You then sum up the decimals and do some divisions to get your rated price & percentages.

Why don't they have to pay tax? Surely this is a business.
