In the sample below is a small zoomed in clip of one of the many types of Spatial joins we process. In this case the green area is a rough representation of an service area submitted for processing and due to the size and scope of the geography, snapping the polygons to match the road base is time prohibited. By increasing the offset of the address points to say offset 35 ft, in this case, allows for a higher percentage of correct analysis being obtained. Depending on the quality of the service area, offset adjustments have been made to the geocoders offsets, and the appropriate coded addresses are run against the particular national service areas. Tight for tight, loose for loose.
Its a little extreme but a 2 ft offset, which we rarely would use, would both add and eliminate address depending on the quality of the service area and we found that certain offset settings work best with certain service areas.
In relation to spelling, historically we run it pretty tight, however we haven't run a recent analysis to see how the newer ArcGIS Pro 2.6 Locator likes or dislikes misspellings.
Not being able to adjust offsets is a game changer, in the wrong direction us at TR
