Internal Timing Test
Keep counting after you see 1, 2, 3, 4, 5, 6, 7, 8 with the metronome click. You continue with 9, 10, 11 ….
You can stop the counter by pausing the video, so put your mouse cursor above the pause button to make it easy to press. Or be ready to press it if you’re using a touchscreen.
