I looked at the telecast and watched the 6th semi time and time again. You can clearly hear the gun before Tiu moves in the first start, he got a blinder. Steffenson has clearly left the ground before the gun is heard and he is correctly called a break.
The 2nd start when they call Tiu for the break, you can clearly hear the gun before Tiu moves. He didn't break. I checked that a few more times and it is obvious he doesn't break. I then watched the replay in slow motion when you can't hear the gun but you can see the smoke has left the gun from the right had of the starters pistol and the smoke has travelled over to the starters left shoulder before Tiu moves. (Chris Perry the commentator incorrectly believed it was a break when he looked at it in the slow motion section because he sees Tiu beat everyone out but he cant compare it the noise of the gun in that film section, and he fails to compare it to the smoke to make that judgement, he makes it purely on who left first with no comparison to the gun noise or the smoke). Tiu didn't break, but unfortunately for him he was so good that that the starter has called him for a break because he beat everyone convincingly, but he still didn't break. I compared it again and again to both smoke and noise and he still hasn't moved before either of them. Definately a bad call by the starter and Tiu would most likely be the unluckiest Gift runner I have seen in recent times.
Otherwise it was a great carnival and a great win by Wiltshire.
