    Eldrick...thanks, my estimate (8.87) was only .007 off!

    Splits semi and final 100m Berlin

    According to this site the IAAF published the splits of the final and semi final
    (http://1.bp.blogspot.com/_ua8ycqfc4ok/S ... /Table.gif)

    Nuther question, which we'll get from our Yankee futbol brethren:

    How fast was Bolt's 40-yard dash?

    Apparently, his time at 40 meters was 4.64.

    Don't have time to do the math.

    big guy

    we don't have his splits so we have to make them up

    assuming he ran the race "perfectly", his splits woud be ~ 100m = (2* 60) - 3.00

    meaning his 60m split was 6.29 & last 40m was 3.29s

    assuming last 40m was 0.01s/10m interval slower, means he went

    0.8075 , 0.8175 , 0.8275 , 0.8375

    take the cut-off at 100y = (( 100 - 91.44 )/10) * 0.8375 = 0.7169s

    -> 9.58 - 0.7169 =

    8.863s

    Using a probably-accurate conversion of 1.0856 for yards-to-meters, 9.58
    would be about 8.82/.83 en route. The 'official' 10m splits will help pin down
    a 100y estimate. But as has been said, those 10m splits are questionable, unless there are 100% accurate, coordinated cameras at each 10m, which
    there aren't.

    I see recall some discussion in the past about this.

    Presumably Greene's 9.79 was first sub 9 100 yards? (on JRM's conversion)

    All we need to know is Bolt's last 10m 'split'. The worst I suspect it could be is .84, which gives him a 8.87 100 yards (or 8.6 - 8.7 hand-time)

    started a topic What was Bolt at 100 yards?

    What was Bolt at 100 yards?

    Back in the day when the WR for the 100 (yards) was 9.3...and it had been 9.3 for so long (Mel Patton the first?) I never thought anyone would ever break 9 flat. But Bolt undoubtedly did today enroute to his 9.58...I 'm guessing his time at 100 yards was 8.87. Which means Gay was also just under 9.00. What is the appropriate conversion?
Working...
