There's nothing wrong with making a move 600 out - or more than that. If the tempo of the race is going to result in a sprint home, then putting the pace on at a time to suit your own mount is a perfectly reasonable tactic.
The problem is the inability to judge pace....and that problem - IMO - is endemic, as is the inability to 'read' a race among officials.
My apprentices were expected to work to the clock. If I wished an even work at 14 to the furlong, then that's what I expected to happen.
They became good at it, and were constantly among the leading riders around.
They hated being made to do it, though..! one lad, who moved to Sydney upon the ending of his apprenticeship, was riding work for Gai Waterhouse. The lass still working for me rang him to catch up, and in the conversation complained bitterly about the 'bitch' [ me ] requiring her to work to time. ' I thought it was crap, too,' said the lad, 'but now I realise just how important it is. Listen to her.'
I cut out a newspaper article from years ago where David Walsh had been charged with 'not giving his mount every chance..' Stipe at the time was Noel McCutcheon, who seemed to have a god-like status among the fraternity.
Walsh, although not always everyone's favourite, has long been recognised as one of the finest judges of pace produced in NZ racing.
David was trying to explain that the horse he rode, upon which he won the previous start, was not able to take a similar handy possie as the leader was an apprentice girl ' who was attempting to go through the sound barrier' . The pace was suicidal, he pointed out, and his horse would have been among the first beaten. He eventually ran on to finish fourth on this particular occasion.
The pace of the race, said McCutcheon, is irrelevant.....FFS, the pace of the race is everything.
