5 Seconds Rule

I was reading a online magazine and came across an article which seems interest.
The 5 seconds rule.

It seems to best time to capture movement is between 4-6secs. Thus, the 5 second rule.
Fast moving subjects will be almost invisible in the frame which the other subjects will give the picture the element of movement.

Method suggested.
1) Tv priority 5 seconds
2) Tripod or on a stable footing
3) Low ISO to reduce noise
4) Remote shooting or Mirror Lockdown

And there you go, picture perfect, or so it seems =)
Will try once I have time and chance
