I enjoy making things.I like tools that speed up accuracy and marking out. Last week I made some T-nuts to enable me to add a pair of 1" thick sliding sub fences, to my Incra fence (I am not buying a Wonder fence. I had to use a vertical milling machine to shape the metal bar(I made 5 T-nuts) then drill and tap. I needed my magnetic base and dial gauge to set up the vice. I last used the dial gauge to set up my planer blades after I resharpened them. I will make/covert my spare LCD gauge to a vertical height version. So when I change bits, or require that bit of accuracy, even though it may only be to the nearest 0.5mm, I know it will be there, not there-abouts, for certain things.I have a Jessem router raiser. Measure thrice, check twice and cut once. My school technician and even my cleaner (an ex-machinist) talk and measure tolerance in cigarette paper thicknesses.I am quite happy in 1/32", especially with the Incra system, so why not be accurate. As my eyesight deteriorates and if I do not put on my reading glasses, the LCD readout is a quick check/indication of me being in the ballpark.
