A scientific instrument that is unreliably accurate is useless. Imagine a kitchen scale that always gave +/- 50% every 3rd time you use it. Or maybe 5th time. Or 2nd.

So we're trying to use tools like this currently to help solve deeper problems and they aren't up to the task. This is still the point we need to start over and get better tools. Sharpening a bronze knife will never be as sharp or have the continuity as a steel knife. Same basic elements, very different material.
