We combined overlapping topics and removed repetitive pages. These guides cover the questions that are most useful for understanding your score, improving performance and comparing hardware.
Understand common score ranges, what a millisecond result means and why one fast attempt is not the whole story.
ResearchSee how reaction speed changes across adulthood and why individual variation matters.
PerformanceSleep, fatigue, caffeine, exercise, attention, practice and day-to-day variation in one guide.
TrainingPractical ways to train consistently without confusing practice effects with permanent improvement.
TestingBrowser timing, repeated trials, home testing methods and how to build a more reliable baseline.
Test typesUnderstand why different reaction tasks produce different scores and what each one measures.
GamingWhat matters in FPS and action games, and what research actually says about gaming and response speed.
Hardware60–240 Hz displays, frame time, mouse polling, touchscreen differences, FPS and ping in one hardware guide.
AimAccuracy, target acquisition, target size, movement distance and Fitts’ law without unnecessary overlap.
ScienceA careful, fun comparison of human browser results with very different biological response tasks.
