Secondly you have to know that that minimum shutter speed is as true at 10mm as at 22 mm, the long end of the focal length of a zoom determines minimum shutter speed on all zooms, many don't know that.

Probably not well known because it is complete rubbish.

I agree, this makes no sense. The minimum shutter speed recommended should be calculated from the actual focal length used for a particular shot, regardless if the lens is a zoom or prime.
