well the only controversy over the gate start was because of michael robinson was in the lane next to graves in the semi final and started his snap when graves did and he flipped the gate, he made a protest, the officials kept an eye on his gates from there, and found nothing wrong with them.... he only comes back about 8-10 inches off the gate, ive seen riders in america on videos do slingshots of around 2ft!
it seems like graves comes back very slowly and therefore early which gives the impression of a big slingshot, but it isnt big at all.
Robinsons screwed up gate in the semi showed one thing......that he was obviously pretty worried about graves and should have concentrated on himself....
Khalen Youngs move on Graves was a bit of an asshole effort, Jareds reaction was "whatever...that was a love tap compared to what goes on in world cup 4X"
