A system assigns a value with many decimal digits and the user interprets it as very accurate. I propose to ask what you measure, with what data and what uncertainty.

In the example, the figure describes a useful estimate only under specific conditions. The number of decimal places shows no quality.

A professional decision must consider relevance and limitations, especially when small differences are used to distinguish people or priorities. The representation of the result should not suggest more certainty than is available.
