0.05s meaning the end of your world champs is brutal

This might be a stupid question, but why is a reaction time of <0.1 (as opposed to <0.0) count as a false start?

It looks like he's been bulking up for football and it's made him less agile.

Did anyone else notice Dina Asher Smith had red liquid pooled at bottom of her uniform ?? Is she bleeding?

Strange they’d have the camera in Shericka’s face even as she was changing her top in the tent.

But boy, she looked built like a tank in that sports bra.

Probably to account for margin of error in the equipment.

Jackson definitely looked easier than ETH.

I think it is because they have to respond to the sound of the gun before starting, and they have decided the fastest someone can physiologically respond to the bang of a gun is 0.1 seconds (and less than that is them anticipating it and going early)?

The cameraman has been wilding today - got kicked out of the call room earlier lol!

Because humans are unable to have reactions that quick. They don't want runners trying to anticipate the gun and get a lucky start (0.0).

Good sportsmanship. If she would have pulled a Jon Drummond we would still be waiting for heat #2.

Because humans have been scientifically proven to not be able to react to a gun faster than .10 seconds.

So any reaction time faster than that means they didn't react to the gun, they started moving before they heard the gun.

The current false start criterion used by the IAAF is based on an assumed minimum auditory reaction time. If an athlete moves sooner than 100ms after the start signal, he/she is deemed to have false-started.

SAFP looks like an absolute darling. So stylish.

It’s kind of weird that there’s no running under protest and figuring it out later. Seems very quick to just have to leave the track

Based on these 2 DQs and Allen's 0.101 someone above noted, it does seem there could be a case for reducing the limit (knowing almost nothing about it)

Allred's was pretty clearly a false start. She was out quicker than anybody else and seemed to guess the gun timing. Gaither's was not a false start other than that she reacted quickly.
