There may be no little orange dots, but there are not black ones either. You pick out spots on a deer just like you do on a target (not a round spot but a place of reference). A hair out of place, wet spot, etc, Or, you put an imaginaryplace through the vitals that you see your arrow going. A big paper plate does not give you that reference point until you at least put a hole in it. I'll even shoot at a burred up place on the target instead of a dot.

In the winter I shoot out to 120 yds outside and never at a dot on a target.
