Some more details about the Devon Allen saga.

1) It had been quite the breakout year for Allen leading up to Worlds. He had been seen as one of the top US guys in the 110 hurdles, but not challenging the best. Best time of around 13.00. Meanwhile, Grant Holloway ran 12.81 a couple years back, nearly breaking the World Record (12.80). Then out of nowhere earlier this year, Allen ran 12.84, the third fastest time in history.

2) Despite this, Allen nearly missed the US Worlds team. His dad died shortly before the race, and it's not clear whether he knew about this, and it could have impacted him. Either way, that's a lot to deal with emotionally leading up to the biggest meet of his life.

3) Allen's reaction time at Worlds was 0.099 seconds, and the threshold for disqualification is 0.1 seconds (not 0.99 and 1). Reaction time is the amount of time between the gun and the moment where the athlete triggers the pressure sensor on the blocks. The idea is that athletes should not be allowed to "time" the start, as this can potentially give up to 0.1 advantage over the rest of the field, a massive benefit. The rule is coming from a reasonable place; you want sprinting to be about who runs fastest, not about who guesses best.

4) As is often true in sport, the "science" surrounding the 0.1 second cutoff is very shoddy, barely science at all. There's some suggestion that ultra-fast starters (of which Allen is known to be one) can sometimes react faster than this, but again, the science is not nearly robust enough to support any conclusions with much certainty.

5) There was clearly a problem with these sensors throughout the meet. There were several DQ's, and across-the-board, reaction times were around 0.02 seconds faster than in a typical "regular season" (Diamond League) meet. Allen was DQ'd in finals for being 0.001 seconds under the cut-off, but his reaction time in semifinals was just a couple thousandths slower. So however correct the 0.1 second threshold may be under certain circumstances, the circumstances at Worlds were clearly different.

6) After Allen was tossed, Holloway won the final. A bit anticlimactic, since we missed the face-off we were hoping for, but Holloway is a special runner, definitely #1 in this event for now. Hope to see Allen come back after football and give Holloway a real run for it!

Great essay. I'll add that exhibit #69420 of how replay and computer and video have taken us away from the fun and soul of sports and games: the stupid, stupid, STUPID thing where if a baserunner loses contact for a fraction of a microsecond with the base they're attempting to take on a close play, they can be called out. The human eye wouldn't be able to see it, but stopped digital hi-def video can. It has to be my least favorite thing in baseball right now, and that's saying something because I'm a Brewers, Twins, and Mets fan.

GREAT essay. And now I know more about the world of chess, and track and field, and I'm irritated at both of them.
