If any athlete were to produce <0.1 second reaction times on a regular basis, they'd presumably challenge the rule
That's not what I mean. They don't wait for the sound of the gun, they know when it is going to be. This means that they train to go in the smallest amount of time possible after the gun has gone off. If they were purely reacting to a noise it would take them much longer to take off than if they practise for it (as they do).
Quote:In competitions held under Rules 1.1(a), (b), (c) and (f) and for any
performances submitted for ratification as a World Record, the
starting blocks shall be linked to an IAAF approved false start control
apparatus. The Starter and/or an assigned Recaller shall wear
headphones in order to clearly hear the acoustic signal emitted when
the apparatus detects a false start (i.e. when reaction time is less than
100/1000ths of a second). As soon as the Starter and/or an assigned
Recaller hears the acoustic signal, and if the gun is fired, there shall
be a recall and the Starter shall immediately examine the reaction
times on the false start control apparatus in order to confirm which
athlete(s) is/are responsible for the false start.
Firstly, I take back what I said, I just couldn't believe that the system would be like that, in fact I still can't.
Secondly, doesn't this mean that if you leave after the noise of the gun, but before a tenth of a second, you don't get a DQ but the race starts again? Those rules are so goddamn unclear. :/
