This is probably too literal an interpretation, but it’s similar to some of the best advice I’ve received for woodworking: sneak up on the cut. When I need to cut a piece of wood to an exact precision, I end up making 5-10 cuts to shave off a tiny piece of the end, check if it’s right, and shave again if needed.
Same with lathe/mill work. You repeatedly remove about 90% of the remaining material that needs to be removed, until you're within tolerance. Trying to aim for removing 100% will mean you'll definitely overshoot.
