Book excerpt: In Mordin On Time, Nick Mordin sets out his method for answering the most fundamental question facing punters in any race, namely: which is the fastest horse? He was timing the sections of races with a stop watch, estimating wind strength and direction, adjusting for movements of running rails, using projected times and calculating average times years before the best-selling American books on speed rating were published. This new edition incorporates much new material, including standard times for all Irish racecourses (plus the major French ones). Mordin On Time enables the reader to construct their own speed ratings wherever they live.
