Athletics, false start rules...

[R1Geezer]

In the 100m semi that Bolt was in, he false started so got a yellow marker, fair enough, then the someone else false started and got a red, ie disqualified. Seems a bit unfair to me and almost encourages a "tactical" false start to put everyone on edge. Not suggesting Bolt did this, he could win it without the blocks at all! Anyway is this a recent rule change? What is the logic behind it? seems flawed to me. Also anyone know the reaction time below which decrees a false start? thanks

being changed next year:
Quote a reectn news item:
"The International Association of Athletics Federations agreed at their Congress meeting to adopt a no false start rule from January next year.
The resolution was proposed by the IAAF Council and is aimed at preventing athletes deliberately committing a first offence to put pressure on their rivals.
Currently one false start is accepted in each race and competitors who subsequently commit another are disqualified.
The IAAF believes 2010 offers a perfect opportunity for athletes to come to terms with the new regulation as there are no major global competitions."
