Can't get below ~250ms ... -.-
But I did a different test once ... It was a car interior with normal throttle and brake and a few lamps in front of the windshield at some distance. You had to press the throttle to keep "the car" at minimum 50 km/h ... and then one of the lights turned on and you had to do an emergency braking, it measured the time from the light going on to you touching the brake pedal and then measured the force you were able to apply resulting in a total stopping distance...
I got 330ms on average with 102kg or ~1kN of force (i just weigh 65kg and the result was better than for most that were def. heavier than me ...the ladies had the lowest results of the group ofc) ... distance got calculated at ~16m ...
So i really wonder why the result with clicking a mouse button is only 50ms faster than actually moving my foot off throttle and onto the brake
OR i really just have very fast feet
