I have been around carpentry most of my life and I don't remember anyone ever using 32nds., most people these days that we hire have trouble with 1/4" measurements, most of the time when they call out a measurement it sounds like 2" and 3 ticks.....
I should have added. I use a 2mm mechanical pencil when doing general stuff and switch to a .07mm for trim. If I am doing stain grade trim I use a razor blade to make my marks.
