Does everyone else picture a watch or clock hand ticking in their head, counting 1 by 1? I got 5.45ish pretty consistently. Reading other scores here, it's pretty amazing we're as good at this as humans.
I use a vocal click like a metronome, three clicks to a second. Can do it with my mouth closed, of course. Got 5.3 seconds.
I pulled up a metronome web app in another tab and set it around 23 bpm. And it still took me about an hour to hit 5.5.
That’s clever, never thought to use anything faster than a second for mental counting.
The bulb flickers at about 1/3 of a second in my browser.
As a child I was taught to count out 1 one thousand, 2 one thousand, 3 one thousand... I used a clock to set my cadence the same day that I received this instruction, and I've recalibrated a couple of times since. 5.25 first try. 5.44 second try.
