What is the average human reaction time?
A scientific study investigated reaction time in 1469 persons ranging in age from 18-65 found. They found that the average reaction time was 231 ms (adjusted to 213 ms when corrected for hardware delays). They also found that reaction times slow down with age (0,55 ms/year)
The human benchmark test might have some inaccuracy due to unfocused attempts and low-performing computers which cause the high average.
