Blake finished 6th or so on a terrible sprint in the Diamond League a week or so ago at 200m.

isn't that a false-start-inducing reaction time?

Athletics (track and field)
In track and field sprints, the sport's governing body, the IAAF, has a rule that if the athlete moves within 0.10 seconds after the gun has fired the athlete has false started.[2] This figure is based on tests that show the human brain cannot hear and process the information from the start sound in under 0.10 seconds.[3] This rule is only applied at high-level meets where fully automated force or motion sensor devices are built into the starting blocks that are tied via computer with the starter's gun. In the vast majority of lower-level meets, false starts are determined visually by the officials.

From 2003, IAAF rules stated that after any false start committed, all athletes were to be warned.[4] Any subsequent false start by any athlete, or athletes, led to immediate disqualification of that latter athlete. Previously, disqualification occurred only after the same athlete false-started twice.[5]

An analysis of start times by sprinters at the 2008 Beijing Olympics demonstrated that male and female sprinters can achieve reaction times of 109 and 121 ms in one out of 1,000 starts.[6] The same analysis showed fewer false starts among the women and it suggests that the apparent sex difference is caused by the use of the same starting block force threshold for males and females. The authors calculated that were the force threshold to be reduced by 22% for females, to take into account their lower rate of developing muscle strength, then males and females would exhibit similar reaction times and numbers of false starts.

In August 2009 the IAAF announced that from January 2010, a zero-tolerance stance to false-starts would be adopted. Athletes false starting are now immediately disqualified.[7] The following year the rule led to prominent disqualifications at the 2011 World Championships in Athletics: world record holder Usain Bolt was disqualified from the 100 m final and 2008 Olympic champion Christine Ohuruogu suffered a similar fate in the 400 m heats.
