These probably make as much sense as a lot of other things we do. Not many of us have the equipment to measure "exactly" - and "close enough" is what we have learned to live with.
Those engineering types that measure things in terms of "One inch plus or minus 1/1000 inch" taught me that "exact" is difficult to achieve.
