I haven't been able to find reaction speeds among Star Trek races anywhere and reaction speed is something that is almost never seen highlighted on screen in Trek.
In real life, Reaction Speed is the time to initiate a physical response to an auditory or visual stimulus. Audio reaction times tend to be 10% faster.
Exceptional: <150ms (Fastest possible human reaction 100ms)
Good: 150-250ms
Average: 250-270ms
Slow: 270-350ms
Extremely slow: 350-500ms
What might be the possible reaction speeds among the alien species of Star Trek, given the evidence from on-screen or novels and how does it compare to humans?
