My woodworking mentor rarely made these kinds of mistakes. He was able to focus very clearly on this kind of spatial object thinking. Me, sometimes I measure twice on a completely different number. 60-13/16 becomes 61-13/16. I get so focused on getting the 16ths accurate that I completely overlook the fact I’m an inch off. That actually happens so often that I remeasure 3 times to make sure I’m in the right location and I still mess up sometimes. The worst is when I’m rushing things, of course.
