Dear all,
The discussion on Bolt's World record is interesting. I note the
discussion paper considers correction for more favourable wind
conditions and suggests that 9.50 could be within reach. I see no
consideration of the effect Bolt's rather poor reaction time (0.165 s).
Assuming that Bolt could react as well as the best athlete in the race
(0.133s), this would allow an improvement of 0.032s. The IAAF limit for
legal reaction is 0.100s. If Bolt got the best possible reaction then
the performance could have been 0.065s faster. This might translate to
best possible a performance in ideal wind conditions of 9.44s !
