Race Ratings for National Hunt Horse Racing
HOOF race ratings are designed for a statistics-grounded value approach to National Hunt horse racing in the UK. Unlike conventional race ratings, they offer the backer an authoritative guide to both form and value. The program which generates the ratings uses Bayes’ theorem to calculate each horse’s chance of winning. The resulting figures are then recalculated to give an edge in the backer’s favour. Hence the acronym: Horserace Optimum Odds Forecast.

'The Punter's Revenge' Free Online
Selected chapters from the old classic ’The Punter’s Revenge’, which I co-authored in 1987,  are now available as an online resource in PDF for those interested in statistics and  statistical approaches to horse racing.  The book is very dated in places, but the statistical principles and methods that we advocated all those years ago, still hold.  For technical reasons, the PDF version is not available on this site, but can be accessed by joining the HOOF discussion Forum.
