They would have had the track in tip top condition for the big night Katie and you wouldn't think they could have all those times wrong BUT I can see your point - Cut For An Ace is a 10yo improving his best MR by 2.5 secs

Edit: I have since found that he was only beaten 9.5m when they went 1.52.5 so maybe it was only a 1.5 sec personal best for Cut For An Ace - still amazing for a 10yo
