The world will have to wait another five weeks for newly titled World Thoroughbred Racehorse Rankings Conference to confirm Silent Witness as the best older sprinter on the planet for 2004. The annual conference of handicappers from all corners of the world has been in a lock-up for three days as they negotiate the merits of horses from their own jurisdictions, with a view to publishing the most comprehensive-ever set of international rankings on January 18. Co-chairman Ciaran Kennelly (Hong Kong) said the conference had determined to publish rankings of the world's best racehorses twice a year. There will be a conference in June or July, to concentrate on southern hemisphere horses and another in December, where the primary objects of their assessment will be the northern hemisphere bred and raced animals. 'One of the main purposes of the conference will be to achieve a greater level of consistency in the ranking of horses,' Kennelly said. 'Handicappers have shown a willingness to address the concerns.' The major criticisms have been that Australian horses, in particular, have been too lowly ranked in the past and the Europeans - particularly English sprinters - have been assessed too highly.
