You could probably rig up some way to measure a single link with a digital something or other, but using 12 links or12" magnifies the wear by 12 (or more than twice as much as five links / inches), and makes it much easier to see wear. Other than using your new digital caliper, I'm not sure why you prefer that to a tape measure or ruler.
Agreed. Digital calipers give the illusion of precision. In reality you cannot line up the calipers perfectly square or orthogonal to whatever you are trying to measure. Try to measure the seat tube hole for example- you'll get totally wrong numbers. So all that precision is misleading.
