What it measures
Each target's time runs from the frame it appears to your click or tap on it, so it combines spotting the target, moving to it and pressing. A miss is a click inside the arena that does not land on the target, and accuracy is hits divided by all clicks. The next target always appears a fair distance from the last one, so every hit needs a real movement. Your personal best is the lowest average for each target size.
Size, distance and Fitts's law
Small, distant targets take longer to hit. Psychologist Paul Fitts described this in 1954: the time needed to point at something grows with its distance and shrinks as it gets wider. That is why the small setting is slower and better for training precision, while large targets make a good warm-up and suit touchscreens.
For steady progress, stick to one size and target count and compare averages rather than single runs. Mouse sensitivity, pointer acceleration and display lag all change the result, so keep them the same between sessions.

Questions
Can I use it without a mouse?
Yes. Touchscreens and trackpads work, and each target is a button: with a keyboard, the target keeps focus as it moves, so press Enter to hit it. That makes it a test of a different skill, so compare keyboard runs only with each other.
Why do my times vary so much?
Some targets appear close to your pointer and others across the arena, so single times spread out. The average and median over a whole run are the numbers to compare.
Will it improve my aim in games?
It trains the same quick point-and-click movement, but games add tracking, recoil and their own sensitivity settings. Use it as a warm-up with your usual mouse settings.
