Just to pick a nit - remember the lookouts in the original message are using best estimation by strictly visual clues and experience - like the point system. When you use the Nearest Visual button it is presumed that the WO is now using the UZO (or something similar) to get a more precise reading of the initial contact report. That is for bearing - range is still an estimate as I believe only a periscope view has the markings to get any accuracy - the UZO didn't have any such, nor the binoculars used by the bridge crew.
