I have a point layer that has two fields representing the distance (in feet) of a point feature to coastline (old distance vs. new distance). I want to crosscheck both fields to see the accuracy of my new distance calculations compared to the previous. Is there a way to select/export all point features have distance value calculations with a less than 5% change in value from the old distance calculation field compared to the new distance calculation?

("old distance" * 0.95) <= "new distance" AND "new distance" <= ("old distance" * 1.05)

Enter this into the select by attribute dialogue and save all selected features to a new shapefile.
