Judgement of pace is everything. Seemingly not taught much if at all, now. One or two trainers place importance on times for their riders but not many IMO.
Haven't seen a stopwatch for years.
A half in 52? bloody hell, they'd go better on a H10 at some tracks. Back in the day [ a long time ago ] George Humphries told me that if they couldn't run a half in 48 they wouldn't make top horses. Nowadays that wouldn't win a trial.
My apprentices were sent home with a stopwatch and tested later. One apprentice left for Australia when he came out of his time, rode work for Gai. The younger apprentice would ring him from time to time, complaining about me. The bitch is at me about times, jeez, she pisses me off. Used to piss me off too, he said. Now I realise how important it is. Listen to her.
My partner had a clock in his head. He could tell you how fast he had worked to within a fraction of a second. And was particularly effective off the front as you might expect.*
