Thanks, topsy99, its nice to know my figures aren't way out.
I agree with your high opinion of J Cassidy. A few years ago, friends of mine raced a horse (out of Canberra) which used to throw its head about in races, clearly affecting its performance. Jim rode it three times in midweek races, for a win. What he did, though, was to teach the horse to race better. Later it won and was placed at Saturday meetings (other jockeys), and the owners were sure it was Jim's guidance that improved the animal's racing manners.
Good punting,
