Correct prompts and mistakes are counted separately. Response time begins when a prompt is shown and ends when the correct physical key-down event is received.
A correct combination needs the displayed modifiers as well as the target key. Speed is useful only when mistake counts remain comparable.
Browser and system shortcuts may intercept combinations. Avoid shortcuts that close tabs or leave the page when selecting practice keys.
Browser or operating-system shortcuts can intercept combinations. WASD mode uses individual direction keys; hotkey mode requires the displayed modifiers.
Some shortcuts are reserved before page scripts receive them. That is an input-routing limitation, and does not by itself show a broken keyboard.
Start practice and focus the test surface. Press each prompted key or modifier combination.

Power settings, background tasks, browser scheduling, operating-system input processing and device settings affect measurements. Compare repeated attempts with identical settings rather than the single highest score.
