After clicking the practice button in the movements panel, you get a screen that can be used to try out the current settings. By performing simple tasks, you can get an impression of the speed and accuracy of your cursor movements.

Start by clicking the red dot. Then move the cursor, as fast as you can, around the green figure until you reach the dot again, keeping the cursor in the green.

A black line shows the trajectory of the cursor. As soon as you reach the red dot again, the time (in seconds) it took to complete the task appears in the middle. Also shown is the percentage of time spent in the green.

By clicking one of the three buttons in the lower right corner, you can choose a different figure.
