So in looking at a design with lots of holes for mounting ziptie clips to hold wires in place I got to wondering...

How many other people still locate holes that do not require precision based on fractions?

Having grown up using a tape measure to quantify distances I find myself drawn to fractions by default. 

Why locate a hole at 5.25 instead of 5.2?  Because .2 just looks weird compared to .25

And I know this is an American thing because most of my European counterparts are not used to using fractions.

Am I alone in this neurosis or is it common even though everything is now machined on equipment that allows any decimal you desire?
