3 second rule

[Paul Klaver]

The count does not start with 1. It should actually start with 0.
And it is better NOT to count like 1,2,3.
It is MUCH better to count like this:
seventy one, seventy two, seventy three.
That way it is closer to the actual seconds on a clock.
And if people speak too fast in general it is even better to count like this: onehunderdandone, onehundredandtwo, onehundredandthree.
You can check your own count with a stopwatch. Reading the last line is almost perfectly aligned with a real stopwatch!!
