Quick questions

Why does the timer disappear?
It hides after two seconds so the rest depends on your sense of time.
What happens if I switch tabs?
The round is cancelled when the page is hidden. It does not count as an attempt.
How is my best score measured?
The smallest absolute difference from 10 seconds wins. Early and late stops are treated equally.
