What's a good reaction time?

Average human visual reaction time is 200–250ms. Top esports athletes reach 150ms. Under 120ms on a click test usually means you jumped early.

Why did I get 'Too early'?

You clicked before the screen turned green — that's a false start, not a reaction. The real timer begins only when the color changes.
