The range of sensory discrimination of a given sense also varies considerably both within and across sensory modality. For example, Kiesow (1903) found in a reaction time task of taste that human subjects are more sensitive to the presence of salt on the tongue than of sugar, reflected in a faster RT by more than 100 ms to salt than to sugar.

The reaction times of the best fast draw shooters is 0.145 seconds, which means that the gun is cocked, drawn, aimed (from the hip), and fired in just over 0.06 seconds. To establish a World Fast Draw Association record, a second shot must be fired in the same competition that is no more than 0.30 seconds slower than the first; this is intended ...
Performances are also hand-timed and calculated to 1/100 of a second, although studies have shown human beings simply cannot react consistently or accurately enough for this to be a valid method, and even those using light beams are timed by the motion of the athlete, removing the normal factor of reaction time; further, football 40-yard dashes ...
The average speed of this race, including the brief reaction time immediately after the commencement of the race, was 10.44 m/s (37.6 km/h; 23.4 mph). [ 109 ] At distances greater than 400 metres , the human body requires oxygen to sustain such paces, and speed significantly tapers at this point.
Scott Flansburg (born December 28, 1963) is an American dubbed "The Human Calculator" and listed in the Guinness Book of World Records for speed of mental calculation.He is the annual host and ambassador for The National Counting Bee, a math educator, and media personality.
In terms of judging a person's speed, the best method of timing is through lasers which start and stop the times when passed through. A laser start (from a stationary position) is more accurate for measuring pure speed as it does not register a runner's reaction time, however, this method of timing a 40-yard dash can affect the accuracy by as much as 0.5 seconds with the manual stopwatch method.
In second place was Leroy Burrell who also broke the former world record, which had been his at 9.90 seconds. In third place, 0.01 seconds slower than the former world record, was Dennis Mitchell with a time of 9.91 seconds. In fourth place, breaking his own European record of 9.97 seconds, was Linford Christie with a time of 9.92 seconds.
[4] [39] As the probe passes around the Sun, it will achieve a velocity of up to 200 km/s (120 mi/s), which will temporarily make it the fastest human-made object, almost three times as fast as the previous record holder, Helios-2. [40] [41] [42] Launch injection was very close to the modelled one, but nevertheless required path correction.
