Five goes, an average in milliseconds, and a number that is almost certainly worse than you expect.
Tap the panel, or use space. Five goes, then an average.
A healthy adult reacting to something they can see lands somewhere around 250 milliseconds. Under 200 is genuinely fast. Anything under 100 means you guessed, which is why jumping early is counted as a false start rather than a brilliant score.
About 80 of those milliseconds are not you at all. They are the signal getting from your retina to your visual cortex and back out to your hand, and no amount of practice makes that part quicker.
A single attempt tells you almost nothing. Reaction times are noisy, and one lucky go can be 60 milliseconds better than your real average for no reason worth reporting.
Five is enough to be worth quoting and few enough that nobody gets bored. The spread between your fastest and slowest is often more interesting than the average, because consistency is the thing that actually varies when you are tired.
The panel turns red and waits somewhere between one and four seconds.
Anywhere on the panel, or the space bar. Jumping early is a false start and does not count.
You get your average, your best, and the spread between them.
