I suspect that when storing coordinates the precision is applied to the value and values are changed acc. to the given precision. Changing the precision will again do some conversion on the coordinates and store new values. Original values get lost. I take the coordinates from GIS services, that offer decimal notation and degree/minutes/seconds notation as well. I have no idea, which of those values is the primary value and which is a simple conversion (not lossless!). So taking the wrong one is the first step where precision might get lost. The second is storing to WP where values might be converted to and fro. When coordinates are imported to wikidata, again a loss of precision occurs. Proposal: Store coordinates in wikidata as they are given (if syntactically correct), allow user chances of that coordinates in case they are considered unprecise. BUT: Apply any precision only for the presentation, not for the stored values.
