Calculation of Horse Rating?

Question

Anyone knows how Horse Rating is calculated? Or how many points to add or minus after a race? and basing on what factor? Thanks.

Answer 1

a horses rating is calculated on the horses ability .the rating represents a weight value in pounds it is judged that these weights would equalize the abilities of the horses if carried in a theoretical handicap race for example a horse rated 120 would carry 5lb more in a handicap race than a horse rated 115 and so on.

Answer 2

The ratings in each country are compiled by the senior handicapper (as we call him here in GB).  The IFHA compile the worldwide statistics.

I don't know the exact mathematics involved but they are established according to how far the horse wins the race by.  I think a length equates to 2lbs, but I may well be wrong.
